2010 Week 6 in Review

This week I had to give up and put a slow bell on the reversing mechanism until I find a piston shaft and hub. Just as a precaution, I visited the Dominion to see if they have a Westinghouse reversing mechanism. Maybe they can help engineer the one for the Maris Pearl1.

A Thanks for Shilshoal Marina

Also this week, we took the Maris Pearl to the Shilshoal fuel dock where we used their bilge pump-out service – a very economical way to get rid of oily bilge waste. Thanks, folks – we hope to keep using this service for years to come.

A visit to Brady’s Atlas-Imperials

I visited Brady on Whidbey Island to take a look at his two Atlas-Imperial diesels. He has a three-cylinder model we estimate as from about 1923 – making it one of the three oldest Atlas Imperial diesels that I know of. Even better, it will run again: very little stands in the way of Brady reassembling the engine and running it.

His four-cylinder needs a bit more work, but can be parted out if it’s found to be beyond rehabilitation:

This first meeting was a great chance to take inventory and document progress on the engines, especially the three-cylinder that Brady’s working on. OTM Inc will be cheering on, encouraging and bothering him throughout the project, it’s that great.

For the rest of you with never-ending projects, consider employing OTM Inc to be the monkey on your back in case your wife is not enough: we have reasonable hourly, weekly, or long-term rates!

Olympic Display

While coming back from Whidbey Island, I noticed that the ferry had a display set up of the ferry Olympic‘s steering gear:

Neat!

More Diving with Sterling

Sterling Marine Services Llc and I dove at the Center for Wooden Boats again to put more barrels under their docks.

2010 Week 5 in Review

Of course everyone heard how committed our president is to saving the antique diesels engines in his State of the Union address, right? Okay, I guess I didn’t, either – but keep sending those notes to him reminding him that good maintenance programs employ more people and for a longer period of time than issuing free engines to replace the heavy duties.

Needed: piston shaft and hub!

This week at OTM Inc, we pulled our hair out trying to find the piston shaft and hub for the Enterprise DMQ reversing mechanism. We’ve been calling everyone desperately, searching and going through miles of microfilm for drawings, but keep coming up empty.

Anyone reading have any information on a Westinghouse reversing mechanism? Please let us know!

Another research trip to Ederer

We went back to Ederer Crane Company (first time was back in Week 52) to look through their records from the Washington Iron Works, and spent a long afternoon looking at even more microfilm of technical drawings and blueprints.

We had a mission, thought: the Catalyst wants to fine-tune their fuel-valve motion and some of the inconsistencies are due to the cam nose so OTM Inc hit the books – or at least the research databases – to find the original specifications.

Washington Iron Works has a simple but hard-to-decipher way of keeping track of their records. Each engine has hundreds of components, each of which has a separate technical drawing or drawings to illustrate its specifications. In order to find the drawings of the cam nose, we looked at the Catalyst‘s original manufacturer card, which gave us a Key List number: 21649-AF. All the key lists are recorded in the microfilm now kept by Ederer, so we looked through the rolls of microfilm to find Key List 21649-AF, which is for 8-1/2″ x 10″ diesels. Each Key List is a list of all the technical drawing numbers for the parts used in that kind of engine, so among all the other drawings it listed, it had Fuel Pump valve motion Drawing #22525-AO, so I pulled that up and took a look. Drawing #22525-AO then said to look at Fuel Cam Nose part number DV-759 on Drawing #8892-AE. Unfortunately, we had to call it a day before I found Drawing #8892-AE.

Incidentally, owner Bill said that the part number on the fuel cam nose on the boat is #DV-2974. Huh. Another head-scratcher is that Drawing #22525-AO is dated June 7, 1933 – but the Catalyst‘s engine was delivered in May 1932. Well, part of research is finding more questions than you answer, so we’ll just keep working on it.

While searching, though, I found a fuel cam nose part #DV-3948 on Drawing number 19754-AH, dated 1930. This drawing also states that the cam nose is for a 10″ stroke diesel, sooo this might be close enough to work from. Also, let the record show I said the cam nose had two angles and the drawing clearly shows two angles.

The Pennsy Barge Collective

A friend in New York is planning on fixing up an antique barge out in New York. He and some friends have started the Pennsy Barge Collective to salvage and restore the old Pennsylvania Railroad barge #399. The group has managed to purchase this last and lovely specimen at its present location in the New York State Canal system dry dock on the Erie Canal, and according to them it’s the last wood-and-steel railroad barge.

If you dare contribute, send your monies to:

The Ever

I talk about the Ready all the time here, but this week I was introduced to her sister ship Ever over the phone this week.

I was looking through the Boats and Harbors and saw a tugboat for sale that look just like the Ready, so I called. The tugs were built in 1941 for Gulf Marine, then both tugs were sold to a Bollenger company called Ever-Ready Towing, who did not like how tippy they were, so they got wing tanks welded on.

Ever-Ready Towing used the Ever and the Ready until the seventies, when the current owner bought the Ever. He gutted the whole boat to make a cruiser out of it, and the original Atlas-Imperial went to the Smithsonian in the early 80s.

Sounds like the Ever is a nice tugboat-turned-cruiser like the Ready, but sadly without the heavy duty. If you’re interested, call Fred at (252) 338-1001.

A visit from Ms. Jack Tar

Kim from Jack Tar Magazine stopped by this week. She’s cooking on the Lady Washington during their winter engine refit and was in town for a bit. It was great to see Kim and catch up on some of the waterfront gossip that doesn’t make it to the various blogs.

Valve-grinding: a team effort

This week, I finished cleaning all the valves for the Thea Foss. Engineer Ron ground the valves and observed that “the first one is fun and the rest of the 24 are boring,” which I definitely agree with. Then Vince came out of retirement and over the mountains to grind the seats, and we had a nice team to get the job done efficiently.

A visit to the Cape Cross

Later this week, I visited the crew of the Enterprise-powered fish tender Cape Cross. The engine’s running well and best of all, the boat is gainfully employed.

Dry-suit repairs

After last week‘s brush with carotid sinus reflux, diver Duane helped me replace the neck seal in my dry suit. Apparently adding a latex neck seal to a neoprene suit is pretty common, and it’s an easy process. First, I coated the sealing area with AquaSeal and let it cure, then I put another coat on to adhere the latex. Then I trimmed it and put one more bead of AquaSeal on edges, and the suit was ready to go.

Giving the CWB a lift

On Saturday, I worked with Sterling Marine Services Llc to level out some of the floating docks at the Center for Wooden Boats by installing some new barrels. Once we got we got a system down, it went really fast. Sterling Marine Services Llc has posted more about it in their brand-new blog here.

Repairs and updates on the Island Champion

I visited the Island Champion this week to isolate the overboard through-hull fixture from the engine. This is an area of excessive stray voltage, which induces electrolysis in the surrounding planks and makes them rot out a lot faster – according to our resources, it’s like nail sickness from increased alkalinity.

I installed piece of hose to separate the engine from the through-hull fitting, which disrupts (in theory) the electrical current running between them:

This should hopefully stop the electrolysis and save the hull timber a little longer.

Also, boat buyers take note: the Island Champion is not for sale anymore.

To bond or not to bond

This brings up the age old-argument: “to bond or not to bond.”

To bond, or not to bond: that is the question:
Whether less noble metals should suffer
The slings and arrows of outrageous corrosion,
Or to take arms against a sea of troubles,
And insulate them. To dielectric: to isolate;
No more; and by isolate to say we end
The corrosion and the thousand natural shocks
That hulls are heir to, ’tis a consummation
Devoutly to be wish’d. To dielectric, to isolate;

On the subject of galvanic corrosion: the way I read it, impressed current is best but anodes are easier and more common. If using anodes, quantity and placement are very important to get right and bonding or isolating is addressed on a case-by-case basis.

Some fittings below the waterline, if isolated, can take a long time to degrade, while others will need to be wired to the anode using a resistance-free electrical circuit with heavy-gauge wire, good connections, and keeping it out of the bilge water. When working with mili-volts, a loose connection is no connection: the mili-volt will not jump a gap. I think it is this sloppy wiring that causes bias in our maritime tradesmen.

More important than the bonding and anoding, boats and equipment should be inspected and repaired regularly – and repairs should be made before small problems are catastrophic. It pains me to hear folks argue about bonding while the boat is sinking. While limiting galvanic activity is important – keep it in perspective!

Update on the Maris Pearl

Meanwhile on the Maris Pearl, we’re down to just looking for the shaft that attaches to the piston in the reversing mechanism and the camshaft gear.

Who’s got one? Any drawings? Anything? Help?

Work begins on the Arthur Foss

The Northwest Seaport started their “Stop the Leaks” project on the Arthur Foss; it sounds like the first step was to take off the big rubber fender on the bow. They took a lot of pictures of it – and better yet, wrote a blog about it! Check it out here!

More work on the Maris Pearl

I’m still working on the Maris Pearl‘s reversing mechanism, trying to track down parts for it. I’ve been working with suppliers and calling collectors and engine owners I know who have spares. The Westinghouse controls rarely need attention, so there’s not a lot of information available on these units. It’s taken some extra time to search it out.

Winter Work on the Thea Foss

The Thea Foss‘s twin Atlas-Imperials are getting some attention this winter. The boat’s engineer worked with Dan to remove all the valves, start valves, and injectors out of both engines, then I spent a lot of time this week disassembling and cleaning everything.

As you remember, this process involves disassembling them each, putting them in a solvent bath, flushing the water jackets, sand blasting and another solvent bath, flapper the guide, and wire-wheel the stems.

2010 M4 Party

The big annual art and music event that OTM helps sponsor now has a not-for-profit fiscal sponsor, so make your donations out to Shunpike, with M4 mentioned as the program.

This year’s show will be the 10th annual, on May 1st. The steering committee is planning furiously, and it’ll be even bigger and better than last year (always our goal).

Working on the bow thruster

We got the new parts and tools to fix my good customer’s bow thruster, but still got caught inadequately prepared. I had to run out in the middle of the job to get more parts.

I also had a problem with my dry suit: the neck seal was too tight. Apparently, this can cause Carotid Sinus Reflex, when your neck seal presses against the carotid artery and makes your brain think your blood pressure is too high and lower your pulse rate to compensate.

The symptoms can include nervousness and a shortness of breath, which at the time I attributed to being out of practice from not diving enough. While it is true I am a little out of practice, the nervousness and shortness of breath were actually due to the neck seal. I’ll replace this before next week, in time to dive next Saturday at the CWB.

Despite all this, we still got the bow thruster fixed right up.

Boats for sale

The Pacific Sunrise is for sale. It’s a sweet boat with an Atlas-Imperial 6HM1125 diesel, and is going for $75,000.

The Island Champion is also for sale. She’s a great boat with a Fairbanks-Morse 35F14 diesel.

New corporate vehicle

OTM Inc got a new truck this week after the old Ford Courier exploded. The new OTM-mobile, a Chevy S-10, has more power and big wheels to fix your heavy-duty faster. It also has working lights, windshield wipers, a heater, and tire tread, all unlike the Courier.

More work on the Maris Pearl

Spent more time cleaning and painting cleaning and painting on the Maris Pearl.

Engineer on the Thea for a night

Every year the Thea Foss‘s crew gets a night out on the lake as guests on their own boat. They put together a relief crew for this night, which provides the dual benefit of ensuring that the Thea has a relief crew that’s “Always Ready.”

It was a great night out on the lake and I can never get enough of the twin Atlas-Imperials – even with their 200 oil points each.

Jensen Motor Boat Party

Jensen Motor Boat Company is an institution of great carpentry and ridiculous sea stories. Once again, I’m very pleased to be invited to the holiday party where there is no end to the wine or food.

I got there a little late but made it in plenty of time for a great party. Thanks, guys!

Museums are not a public service

I know they look like libraries, but most museums are private institutions. They receive tax benefits because they provide community benefits, but this does not mean that they must provide specific services or that individuals are entitled to make demands of a museum. This seems to be a frequent cause of misunderstanding, especially in the old boat community, and I believe it’s important to make some distinctions and clear up those misunderstandings.

Museums benefit communities in many specific ways, one example being by providing educational opportunities, and this grants them tax benefits to support the services they provide. Individuals supposedly benefit the community by getting married and having kids and so they receive tax benefits to support that service. Now, while both institutions are exempt from taxes, this money is essentially being taken from those of us who are not entitled to tax breaks and use the community services. It’s therefore just as unreasonable to demand that a museum “save” your crappy old boat as it is for me to demand that your kid mow my lawn.

2009 Week 38 in Review

Last weekend was the Wooden Boat Show in Port Townsend. Old Tacoma Marine representatives spent some time listening to the pop pop pop of the Elmore‘s exhaust – keep that Atlas running!

A visit to the train museum

On Saturday, I took a trip out to Mineral, Washington to see if they still had an old Atlas-Imperial on display. No joy – they scrapped it last year. Another great old Atlas bites the dust.  They did have a bare engine block from an Atlas 668, though:

On a positive note, it looked like the train museum is doing well. They had an amazing geared locomotive – the Rayonier #2 – in the shop, and there were a few old locomotives with steam up out in the yard.

Check out the list of remaining steam locomotives in Washington State they linked to, and the one for the Mount Rainier Scenic Railroad, too.

Business as Usual

This week, we are back in the shop cleaning, reading the Local Agency Guidelines Manual for the Lightship #83 project, and working on the website some more.

We’re working hard to get pages about all the known remaining Washington Iron Works and Atlas-Imperial diesel engines up on the web. Don’t worry diesel fans – we’ll get to the Fairbanks-Morse and Enterprise sections next.

I didn’t make it to the Tugboat Races in Olympia this year, but I heard the Maris Pearl did very well – it looked like first to me, but we’ll have to review the photo. The Donald R was there in style – we love that Washington.

New tugboat book released

I also got news that Jessica DuLong (owner of the Gowanus Bay) has finished her book and it’s being released this week. She’s been writing it for years and I went out and ordered a copy of it from Elliott Bay Books as soon as I heard. It should be here in a few days – I’ll report back after I read it.

Heavy-duties for sale

To all you Tugboat Dreamers: don’t forget that the J S Polhemus, Oswell Foss and Quail are still for sale.

Keep up with what’s for sale and what’s been sold at OTM Inc’s For Sale Listings.

Heavy-duty sounds through the ages

Engine collector Jim Walsh sent us a nice quote about heavy-duties: “I don’t really work on the engine, I just start it up and listen to it like a phonograph.” We at OTM Inc agree: the heavy-duties sure do sound nice – though we may not be getting the authentic symphony.

Dan told me that Dave Updike, his boss in the 1970s and the Godfather of heavy-duties, said the diesels don’t sound like they did way back when. Modern diesel fuel has a higher cetane than the old stuff, and you can’t even get number two diesel anymore. According to Dave, the thicker fuel makes a deeper thump and a lower “chuf chuf chuf” from the stack.

If Dave said it then it must be true, but we think that the heavy-duties sound just great regardless of the fuel.

20Work continues on the Arthur Foss

This week, I continued to work on the Arthur Foss‘s Washington, working with OTM’s mechanic Crystal. We started the week with two big challenges to work on 1) make a tool to drive out the very stuck air-start valve, and 2) put the very heavy cylinder head back onto the engine.

I had to make a tool to get the air-start valve out. Back in 2005, during the very first session of Diesel Engine Theory, we pulled all the intake and exhaust valve cages out of the Arthur‘s engine. I wanted to pull all the air start valves in the head at that time, too, but they were really, really stuck. I decided that it would be best to take them out when we had the heads off, but I’ve been really antsy to start getting them out.

The day to get them out came on Thursday of this week, when I got to South Lake Union with the tool I’d made. It’s basically a cylindrical steel punch that I put up against the air start valve on the underside of the cylinder, and then wailed on with a ten-pound sledge hammer. It didn’t budge for a while – long enough that I thought “crap, I’m going to have to cut this [censored] out in pieces,” which I had to do with one of the exhaust valves back in 2005. But then I hit it some more and it finally came loose and popped out of the head, and I brought it back to the shop to clean it up. Whew.

hole for the air start valve in the Arthur Foss's number four cylinder head

Later in the week, we used a borrowed three-ton come-along to winch the piston back up into the cylinder, then set the head back on the cylinder. The come-along was a really great tool – I want one. I’ll have to put it on the Arthur Foss‘s wish-list, too.

I picked up a bunch more supplies, including water grommet material in two thicknesses. Then, I had to make a lot of calls and fuss over the head gasket because the manufacturer didn’t have the right material, but I finally got it.

There was also a lot of cleaning and painting all the individual parts. We painted the rockers and valve parts the usual Arthur white and painted the exhaust manifold with high-temperature paint. The TAP guys helped out a bunch this week with the painting – thanks, guys!

With all that accomplished, we were all ready for the next class on Saturday! But first…

South Lake Union party

The Friday Lake Union Park Working Group is still doing great things. On Thursday, they had a big party to “roll out” a new planning document that they all worked on. Lots of people showed up to see representatives from every group (like 20!) speak and everyone was really excited. I’m excited too – ten years ago, none of the different boat factions would even have been in the same room together, and now applauding for each other and finding ways to work together. Way to go, everyone!

Atlas-Imperials are not dead

The Puget Sound Maritime Historical Society just published an article in their quarterly rag the Sea Chest titled “The Atlas Imperial Diesel Engine, an Innovative Engine Built in the 1920s”. While this article gives the Atlas-Imperial diesels credit for being innovating and durable machines, the overarching theme suggests that the engines are gone for good.

I disagree.

Old Tacoma Marine Inc is here to show the next generation that heavy-duty diesels like the Atlas-Imperials are alive and well and still working as they were designed to do almost a century ago. The 500 or so heavy-duties from the four manufactures that I like the most are near-evenly grouped into four active categories by use: commercial, pleasure with a purpose, museums, and collectors. In all categories, the engines must function to fulfill specific duties, and these keep a small but diligent group of mechanics, engineers, operators, parts suppliers, curators, grant writers, museum program managers, and grey-haired guys who know everything all gainfully employed year-round. We’re a tight bunch who meet often and share stories and get their own tables at the tugboat parties or tractor shows.

This network of support and the great need for the engines to run is the reason this article is premature in writing of the death of these innovative engines, built to last from the 1920s and far into the future.

Underwater Surveys surveys the Lightship #83

A diver from Underwater Surveys did an underwater video survey of the Lightship #83 this week. He found that the hull is in about the condition we expected, with lots of aquatic growth – so much that it looks like a coral reef. I can’t wait to haul it out and clean all that off.

If anyone needs an underwater survey of their boat, let us through and we’ll patch you through to Underwater Surveys.

Indian Grave #3 running!

This week, I also got word that the Indian Grave Drainage District’s engine #3 successfully ran for about five minutes. I can’t wait to see them all working!

Diesel Engine Theory Session Four

Saturday morning, we all met on the Arthur for part four of the Diesel Engine Theory class. The first task was to move all the parts from my truck back onto the boat. We brought them all to the back deck to sort them out:

parts from the Arthur Foss's Washington Iron Works diesel engine

We did some more painting and cleaning and sanding, and cut grommets for the exhaust manifold:

cutting gaskets for the exhaust manifold

We also did some old Diesel Engine Theory standbys, such as the Washington Valve Dance (putting spring retainers on the valve stem), the Kerplunk Test (fitting the valve cages into the cylinder head; a “kerplunk!” sound is good, a “squish…” sound means more sanding), and annealing copper gaskets with heat and then cold water:

annealing a head gasket for the Arthur foss's Washington Iron Works diesel engine.

Then we had another amazing lunch cooked in the Arthur‘s frying hot galley with the fabulous Chef Kim, who made cheese sandwiches, tomato soup, and cayenne brownies. She also baked lots more of the amazing bread she made last week, and we all had tons of it.

Fresh-baked bread on the Arthur Foss!

After lunch, we did some more cleaning, then got the rod bearing back in. This was an excruciating job because the rod bearing is two big heavy pieces of metal that fit around the crankshaft. It’s tricky because you have to suspend the lower half while you get the upper half in place and the bolts through. I rigged up some braces to keep the pieces in place, then got into the crankpit while all the students maneuvered the pieces into place.

re-installing the rod bearing on the Arthur Foss's Washington Iron Works diesel engine.

It was hard work (especially since the boat was hot and the crankpit full of solvent), but we got it done just a little after five. Next week is the last week of Diesel Engine Theory 2009; let’s hope we get it all back together in time!

Seattle Power Tool Races

The power-tool races were Saturday evening. I wish I could have attended. Hopefully next year.

Still scraping bearings

OTM Inc spent most of this week scraping and fitting rod bearings for the Indian Grave Drainage Pumphouse‘s Fairbanks-Morse diesels, and making some fine adjustments to the main bearings. I did this with much relief, after getting satisfactory results when testing the main bearings.

Report on the MV Tuhoe

Old Tacoma Marine Inc’s intrepid investigative reporter Jacoba took a field trip to see the Atlas boat MV Tuhoe in Kaiapoi, New Zealand. This neat old boat (the only Atlas boat we know of in the Southern Hemisphere) is an old cargo auxiliary schooner, powered by twin 6EM327 Atlas-Imperial diesel engines.

Atlas-Imperial diesel engine on the MV Tuhoe

Interestingly, the association that owns her (the MV Tuhoe Preservation Society) has a third identical engine that they use for parts. It sounds like they’ve put a lot of love into the boat and they have a lot of community support. Jacoba wrote up a great article about the boat that talks more about that:

The twin Atlas-Imperial engines of the M.V. Tuhoe rattle in well-tuned percussion as John Thompson, one of the ship’s chief engineers, eases on the throttle. The engine room is tidy, and the fixtures are color-coded with bright, glossy layers of paint to help newly-trained volunteers.

Arthur Foss Cylinder Four Overhaul begins!

I flew back to Seattle on Thursday night, just in time for the Diesel Engine Theory workshop on the Arthur Foss. OTM Inc runs this in partnership with Northwest Seaport and the Center for Wooden Boats at South Lake Union. We’ve been planning this session – overhauling cylinder four – for years, and getting ready for the class was stressful since I was in Illinois most of the month. I really wanted everything to go well despite only preparing over the phone, but I shouldn’t have worried too much.

The first session went very well. We had eight participants (a full boat!), including four guys from The Anchor Program (known as TAP) who’ve been doing a bunch of work on the Arthur. After coffee and introductions, we took a tour of the boat, oiled and greased everything, and ran the engine and both generators for a while. I got a lot of good questions and everyone was really interested in the boat and the engine and diesel engines in general.

Exercising the Arthur Foss's AC generator

Part of any workshop we do with Northwest Seaport is the Galley Program, where we use the boat’s galley and especially the diesel stove to make lunches for everyone. Chef Lia prepared the best and possibly the most tacos ever cooked in the Arthur‘s muy caliantá galley:

After lunch, Dan gave his Diesel Engine Theory lecture, which was even better than last time. He brought along a lot of parts to illustrate his points, along with dire warnings to not damage the injector tips!

Crystal examines an injector tip

After the lecture, it was time for the big moment: taking the engine apart and fixing it. I’d gone and gotten a lot of tools while preparing for the class, so I divided the students into two groups. I set one group to taking all the jewelry off the head, and the other group to taking the access panels off the bottom of the engine and getting ready to take the rod off the crankshaft.

George takes apart the cooling system

Now, I bet a bunch of you reading this are thinking “holy cow, he just let a bunch of students start taking stuff apart and he wasn’t watching them like a vulture watches a dying horse?” Well, heavy-duties like the Arthur‘s Washington come all apart pretty easily with socket wrenches and screwdrivers, but there’s a lot of hardware that has to be taken off. All the students were really doing was turning wrenches, but if you’ve never taken apart an engine before, you learn tons from just turning the wrench and seeing how it’s all put together.

By the end of the day, we had cylinder four nearly all stripped down. We got stuck on one head nut just as five o’ clock rolled around, so we left it like that for the night. I’ll have a lot more to report about the class next week, so stay tuned!

The M.V. Tuhoe, icon of Kaiapoi

By Jacoba Charles, OTM Inc Investigative Reporter

The twin Atlas-Imperial engines of the M.V. Tuhoe rattle in well-tuned percussion as John Thompson, one of the ship’s chief engineers, eases on the throttle. The engine room is tidy, and the fixtures are color-coded with bright, glossy layers of paint to help newly trained volunteers.

The MV Tuhoe in Kaiapoi, New Zealand

Emerging to the deck of the 108-foot-long, two-masted wooden schooner one sees the placid green expanse of the Kaiapoi River. Just upstream is the small southern New Zealand town of Kaiapoi, the Tuhoe‘s home port for over 40 years. Before arriving here, the ship – built in 1919 – spent several decades working as a trading vessel. During World War II, she spent three years providing supplies to troops in Papua New Guinea.

Today, the ship’s rich history has made her something of a local treasure.

“This is an icon for Kaiapoi and the surrounding district,” says Thompson of the boat that is now a non-profit, held in public trust for the town. “Everybody just loves it.”

Early years

The Tuhoe (pronounced “two-hoi”) was built to hold 100 tons of cargo in a triple hull made from Kauri. The native timber was once widely used for ship building; the trees grow tall and straight, and the densely grained wood doesn’t shrink, twist, or bow.

For two decades the Tuhoe‘s life was fairly peaceful, running up and down the west coast of the country delivering cargo to all the small ports between Gisborne and Whangarei. She was perhaps a little accident-prone: records show she struck a bridge at Whangarei twice, and in 1929 she collided twice with the ship Coronation. In 1934 she ran aground two times, and in 1937 she got stuck in the Waihou River.

“Most mariners would say it’s more likely to be a reflection of the competence – or lack of – of her master and crew at the time,” Thompson says. “Ships don’t have accidents on their own.”

Everything changed in 1942, when the Tuhoe was called to duty in the Second World War. First taken over by the New Zealand Army, she was then sold to the small ships division of the U.S. Army. For three years, she was known only as Z8 as she ran supplies up and down the small rivers of Papua New Guinea. Captain Couldrey and his crew of New Zealand citizens faced constant risk, yet also suffered weeks of idleness and boredom. Armed only with two 50-caliber machine guns, they would hide from enemy planes under mangrove trees. Once little Z8 towed damaged vessels to safety – something Thompson described as “almost unheard-of” for a vessel of her size, and for which the crew received a commendation.

After the war, the Tuhoe reclaimed her name and was returned to her previous owner, but she didn’t work much for the next 50 years. In 1962 the Kaiapoi Shipping Company bought her, but the following year modernization killed local trade. She was then equipped as a fishing boat, but wasn’t really suited for it. For the next several decades, the ship was just tied up most of the time, Thompson says, describing her condition as “run-down and derelict.”

Life as a non-profit

In 1980, a group of eight locals – including Thompson – decided to salvage the ship and turn it into a resource for the community. She was bought by the Cure Boating Club, under which the MV Tuhoe Preservation Society was formed and operated.

“Both main engines were seized solid,” Thompson says. “It took engineers Jim Wingham and Gary Hullen about two months to free them up. Fortunately, being diesel engines, the cylinders were not rusted, just gummed up with dried out diesel residue. The cam shafts, cam followers, push rods, valve stems, and overhead rocker gear were a different story however; they were rusted and took a long time to free up using CRC and kerosene. Then of course the ancillary equipment including the old Ruston engine and compressor, air valves, safety relief valves, plus onboard engine compressors, all of which provided the compressed air to the air start tanks had to be freed up as did the bilge pumps, bilge valves, and alternator.”

Atlas-Imperial diesel engine on the MV Tuhoe

The all-volunteer crew worked for months to get the Tuhoe mobile again; but when she finally moved under her own power in July of 1982, two thousand people showed up to watch her go.

A year later, the group took passengers out for the first time – taking the cruise from Kaiapoi to the mouth of the Waimakariri River and back that she still does today. Throughout that time, both repair work and fundraising were still intensive. In 1984, she spent nine weeks in dry dock, where the volunteers worked “every available hour,” restoring the aged hull under the guidance of professional wooden hull ship builders.

A few months after she was granted full survey certification and licensed to carry 150 passengers, a major crack was discovered in the port engine’s block. “This was apparently known by the original owners who used to seal it up with Defcon (a plastic metal) to stop it from leaking,” says Thompson. For a time, repairing the engine seemed like an impossible task.

“One day a passenger came into the Engine Room after a sailing and said, ‘I know where there is an engine just like that, a farmer has one in his cow shed on the Coromandel,’” Thompson recalls.

He was able to find the farmer, who agreed to give up the engine. The Tuhoe‘s two original engines were serial numbers 21600 and 21610; the new one fit in perfectly as number 21605. “They must all have come to New Zealand in the same shipment,” Thompson says. “How is that for a coincidence?”

Recent years

In 2004, the Tuhoe was bought from the Cure Boating Club and became a separate non-profit. The river tours had shut down a few years previously due to a dispute between the boating club and the preservation society, and the ship had begun to fall again into disrepair. When it was put up for sale, the locals were worried about where it might end up.

“We bought it back again, and put the ship in trust to all citizens of Kaiapoi,” says Thompson. “It can’t belong to anyone else now.”

Every Saturday these days, a dozen or so of the ships 50 volunteers show up to paint, clean, oil and otherwise keep the ship in shape. They also can get special training in the area of their interest, such as being a captain or engineer. As a result – and to ease the responsibility for the twice-monthly cruises – the Tuhoe now has roughly three complete crews. For example, Thompson says, in addition to the three chief engineers there are six “ordinary” engineers trained to help run the engines.

One 84-year-old volunteer, Captain Anderson, has been with the ship since she was an active trading vessel out of Kaiapoi in the early 1960s and he was paid to drive her. His advice about steering the temperamental Tuhoe was so popular it’s now on a brass plate in the cabin: “Find out what she wants to do and help her.”
