Caledonia yawl project: figuring out the centerboard issue

Not everything works straight out of the box so to speak. Especially if you built the box… Since launching the centerboard has been getting harder and harder to move. Last year after launch I removed it and sanded off the paint on the sides to make it a bit thinner in the hope that it would be sufficient. But on our latest trip last weekend I found it would not go down and we tipped the boat over and although with the leverage of the tip of the centreboard I could slide it down, it was clear that there wasn’t enough space at the opening.

So I decided that I will remove the centerboard and tip the boat over to find a way of filing the centerboard slot a little wider.

Sliding off trailer onto rollers

I tried to see if I could do it all on my own. So I figured it was possible with the beach rollers that are really effective.

I then tipped it over ont a foam mat to protect the rail and used blocks to hold it up by the bilge stringer. This allowed me to work at eye level at the keel slot and will be a good system for the time I need to repaint the underside of the hull.

What I found, was that the centreboard well was fine, but it was at the keel wood that things got narrower and one side for some reason was toed in so it was not parallel with the centerboard well.

I then used a Japanese shinto rasp to file down the section that toed in so that it was parallel with the centerboard well and provided ample room for the centerboard to slide down.

I then sanded it and applied a layer of epoxy with a little graphite powder to seal it back up. It is a hard spot to get to so hopefully this repair will last a long time.

An Aod Oolichan: Year two setting sail

With a wet cool spring we have not yet done much sailing yet apart from a January sail when my mom came to visit.

We got up at 5am to be sure to have a spot to park the car and trailer at Porteau Cove on Canada Day and start our first camp cruising trip of 2022 in the newly named UNESCO Átl’ka7tsem/Howe Sound biosphere region.

First trip with the car and boat on the trailer

Fortunately we arrived and a spot opened up just as we arrived and we were able to launch and park the car for the weekend.

It took us about an hour to load the boats and set up all the rigging. We were off at about 10:15am. Boy was it a good feeling to be on the water and know that everything worked. The car towed nicely, the boat tie-down held the boat well to the trailer, the oars worked and all the other little modification I did over the winter made the launching easier.

And we are off across Howe Sound to a marine trail camp site

The glassy morning conditions meant that we were able to put the ePropulsion 1.0 to the test. Quiet and efficient we glided towards our destination until half way when the early signs of the southerly inflow started a light breeze that pushed us to our Howe Sound Marine trail site.

Solar charging finally works

I was finally able to set up the four 50W solar panels rigged in parallel to the MPPT charge controller providing an output of 170W at 48V to the battery. It was really exciting to see the system creating new autonomy allowing us to plan longer trips without needing to go into town to recharge. The trick is just finding good spots that will stay in the sun for several hours. The next step is to set up the panels on the paddle board and towing it behind us.

The LED refresh rate makes it hard to photograph the output. This little device is amazing.

Our site had several tent pads and a clever composting toilet with a urine separating system that used a conveyor belt to move the solids back while the fluids drained forward. I wonder if this kind of system will become standard practice to replace pit outhouses that more easily contaminate soil and water tables in many camping areas.

The Howe Sound Marine Trail

Day 2 we did a day trip to another Howe Sound Marine Trail site to the south. We set off at noon and got the full force of the southerly inflow on a sunny day. In January I found that the centreboard had a hard time sliding down… which I chalked up to winter humidity levels, But this time again we found that it was still sticky. So I tipped the boat over and did a full check of the centreboard well. What I found is that the keel slot is a few millimetres narrower than the centreboard well. This means that we were not able to point upwind well and I was forced to use the electric motor for the upwind leg. next week I’ll have to take the centreboard out and tilt the boat over again to file down the keel slot a few mm and epoxy seal and repaint it.

On Sunday we found the forecast of rain had moved forward by a few hours and the taking down of camp and sail home was done in the rain with a beautiful veil of clouds clinging to the mountains around Howe Sound.

Some of the things on my to do list coming out of this trip

  • Test using shorter oars maybe 9.5′ long. The 11.5′ long oars worked but might be a little long if there are any waves by providing little clearance. They also take up a lot of space onboard.
  • Open up the centreboard slot 2-3mm so that it does not get stuck even with some sand and grit that is very likely to find itself there after a beaching.
  • Look at finding a rubber, neoprene or vinyl material to create a centreboard gasket.
  • Make a hold down cross beam with eyelets for the tie-downs to attach to and hold the boat from bouncing on the trailer.
  • Paint the name on the boat
  • Make a boom strop to tie the boom vang to.

Overall a very successful trip start building the habit of regular outings.

Calendonia Yawl Project: making oars

This is one part of the project for which there is surprisingly little guidance from Ian Oughtred in the plans or in his book on Clinker Plywood Boat Building. It would be great to have specific guidance on the length of oar and some design options with the plans that are tailored to the boat. Apparently some of his other designs might have that.

I started looking around at different plans out there. Pete Culler, Francois Vivier, John C. Harris (WB #240), Peter Helland Hansen and Wesley Reddick all of which have different sized and shaped blades in particular. I also used the Shaw and Tenney oar length fromula (Divide the span by 2, and then add 2 to this number, Multiply the loom length by 25, and then divide that number by 7. The result is the proper oar length in inches. Round up or down to the closest 6″ increment) and John C. Harris’s calculation ((Beam + Freeboard)+9)x1.34 and have come to the conclusion that I need 11.5′ long oars… whoa that is long.

I also consulted the Wooden Boat forum and found that Caledonia Yawl owners seem to have oars between 9.5′ and 11′ long and there is little consensus on what is the sweet spot. I’ve also really liked the solution offered by Harry Bryan to create a scarf that allows you to disassemble the oars into tow pieces (WB #229).

So my choice is to make 11.5′ oars out of sitka spruce that will have a scarf to disassemble. I can always shorten them if I find it to be too long. If I have the energy I may also make a second set of 9.5′ long oars that would fit on the floor boards on either side of the centreboard between the bulkheads. I figure it is always good to have a backup and 9.5′ might still be quite usable.

I’ve also been inspired by the Small Boats Monthly post on making oar risers for stand-up rowing.

Caledonia yawl project: Playing around with solar power

As part of the camp cruising brief for this project a negotiation with my wife introduced the necessity of having an auxiliary propulsion. Oars alone just were not accepted.

So to that end I purchased an ePropultion electric outboard with a 1275 W 45V lithium ion battery. On our maiden voyage through Howe Sound last year we quickly saw that 2-3 hours was pretty useful but recharging takes 4-5 hours and it was not easily found in marine camp sites. So in the interest of creating more sustainable autonomy I started looking into solar panels. With help of my friend Justin at Grin Technologies, I’m I was able to come up with a 200W panel being a good fit. The battery could be fully charged in six hours and if charging at the same time as running would effectively double the range.

20220129_113338

The idea is to create a solar platform on my inflatable paddle board and tow it behind the boat when running in calm weather. It will guarantee shade free space which is hard to do on the boat with the sails up. Another option is to create a boom canopy that can hold them which is more suited to when the boat is at anchor.

20220129_113144

On a cloudy day with two pairs of 50W panels wired in parallel and then in series, it registered 46V and 0.1 Amps. I’ll try again with some real sunshine to charge the battery from the MPPT. The proof of concept is exciting.

20220129_110317

The nice thing is choosing the smaller semi-flexible 50W panels means I can store them aboard relatively easily and they will fit either lengthwise or width-wise on the paddleboard. All the MC4 connectors are waterproof and the panels are sealed so they should survive mild splashing if I regularly rince them off after a trip.

An Aod Oolichan: the first cruise

Five days after the launch of An Aod Oolichan my Caledonia Yawl designed by Ian Oughtred, I was ready to take the family out on a multi-day camp cruising adventure. We packed most of our camping gear into waterproof bags and I went and found a flexible soft cooler that will fit nicely in the boat and not scratch up the paint.

Set up on the first cruise took a little longer than expected and we headed off at 4pm on Friday from the Jericho Sailing Centre with a nice 8-10 knot westerly. In overcast skies and forecast for rain mid-day on Saturday.

20210903_161524

We got to the shipping lane with a falling breeze and still 10 miles to Halkett Bay. So in the interest of safety we started up the new electric outboard to motor-sail (ePropulsion Spirit 1.0) which is about the equivalent of a 2-3hp petrol motor.

We arrived after sunset into a dark Halkett bay and tied up to the dinghy dock. (An Aod Oolichan is technically a dinghy). The camp sites are in a fairly wooded area of the park up behind the dock. We set up the tent quickly in the dark and made quick work of dinner with one-pot dehydrated Bim Bim Bap meal. To call it bim bim bap was a stretch but after a long day we were happy to have warm food.

The next morning we tried to set off early to beat the rain and get across to Plumper cove and set up camp there before the big rain.

It was a lot of fun to have a nice building SE breeze pushing us ahead of the rainwall.

Unfortunately the rain beat us to Plumper Cove

But the powers of a bag of chips to keep the spirits up should not be underestimated.

The wind did not abate with the rain. We found that as we were turning the corner of Keats island to Plumper Cove. By the time we got to the turn to the cove we were doing 6.5 knots and the breeze was up to 15-16 knots. I had all the canvas up and knew that when on a run the apparent does not feel as much. I did not want to gybe in these freshening conditions. So as we came up to Plumper cove we rounded up into the wind and simply dropped the main sail. Then tacked and came in calmly into the cove under jib and mizzen. Although it might have been a little early to introduce a high wind manoeuvre to my crew, their two weeks of summer sailing camp came in handy and they were able to assist without any problems.

We got a nice spot at the dock and unloaded all the camping equipment in a bit of a deluge.

My Hennessy hammock hexagonal rain fly tarps are a dream in these situations. They come with light high-strength cord tucked into little pockets at each corner making setting up the tarp in the rain a fair bit faster and easier. We quickly had one set up for the picnic table and another to cover the tent. We also set up another smaller rectangular syltarp over a hammock I picked up on Ecuador made of an old fishing net which we used to hang all our wet weather gear.

Plumper cove is a well maintained marine park with it’s own little library.

On Sunday the clouds parted and we set off for a day trip to Gibsons. It was an opportunity to connect with friends who had recently moved there and recharge the battery for the electric outboard that we had depleted on the first let to Halkett bay.

Upon our return to Plumper cove we were rewarded with a beautiful sunset.

And a chance for a summer family photo

… and the end of the fire ban. So an unexpected campfire.

Monday was a return to full sun. We set out early at 10:30am with a 20 NM return trip to Vancouver ahead of us around the south end of Bowen Island.

We had a beautiful breeze through the Pasley island group. But as we reached cape Roger Curtis the wind started to get very light.

For the next few hours my crew dozed as we motor-sailed along the coast of Bowen Island and watched Point Grey and the buildings downtown slowly emerge in the horizon.

It seems like the gunnels are like a favourite place to hang out.

After eight hours we arrived at the Jericho Sailing Centre with a strong flood pushing us.

20210906_155006

Overall I was super pleased that all that time building and thinking about each aspect of the boat meant that the transition to sailing was relatively natural. There are still many little things to tweak in the rigging (make lazyjacks) and the way we stow gear onboard. I was also pleased that we did encounter some challenging conditions that pushed us to adapt and work together as a family. It was a very successful first voyage aboard An Aod Oolichan and I look forward to returning to sailing around Atl’Ka7tsem / Howe Sound which on September 15th was designated a UNESCO Biosphere reserve. How fortunate I feel to have such a unique geography and biosphere right in my back-ocean.

Caledonia Yawl Project: Shakedown

After the launch on Sunday I spent a couple days working through the final rigging for the mainsail and getting a few more small daysails in to test the setup properly.

It was a real pleasure to have all the blocks I made fitted and feel like the proportions I chose were appropriate.

Everything went quite well except that the centreboard was quite tight in the centreboard well when I tried to lower it. It would appear that the extra layers of paint on top of the graphite epoxy finish might have been a little superfluous and causing me grief.

So I removed the thwart to get the centreboard out the next day and saw exactly where it was a touch too wide.

knowing that these parts are well hidden and have lots of epoxy coats. I sanded down the paint and re-installed it in the centreboard well.

Caledonia Yawl Project: Naming and Splashing the boat

What a race to the finish line it was yesterday. I knew things would not be perfect and that my list of to dos was too long to have everything done. But I needed to set a day to splash the boat. I was madly leathering the spars and splicing the eyes for the stays.

20210829_145508
20210829_151531
20210829_151537

And bit by bit people started to stop by and I am grateful for the support and the help I received yesterday. The builder is always really sitting on so much support that allows them to do what they love.

20210829_161954

I put a coin at the base of the mast that happen to be a 2021 pressed Canadian dime of the Bluenose. Which I think is an appropriate choice.

20210829_163033

I ran out of time to rig the main and mizzen sails. But it was really amazing to see the masts up and the jib rigged.

I then took the boat down to the main ramp of the Jericho Sailing Centre and did a little naming ceremony. The boat is called “An aod oolichan” which is a mix of Breton and Chinook languages meaning “The coast oolichan” which to me connects two places and cultures that are important to me. The main fishery in my village in Brittany is the sardine which is a small oily fish that the oolichan kind of evokes for me as an important part of the sea. My boat is not big and so naming it with the name of a diminutive fish seemed appropriate. I also think it will be a coastal boat and so adding the Breton An aod connects it to the coast. It was also the name of my grandmother’s house in Brittany.

Then it was time to splash down and do a little sail under jib alone.

20210829_165940

It all went really well and my first passengers were pleased. In 8 knots of wind the boat got up to 2.8 knots under jib alone which bodes well. The centreboard cap plate leaked a tiny bit at the base and the centreboard was a little stiff. So I have little work to figure out how to make that smooth. But overall she floated on her lines and the launch was a success.

More photos from friends to come shortly.

Caledonia yawl project: Spars and rigging

20210825_141922

I made the remaining thumb cleats, jam cleats and fairleads needed just in time to be varnished along with the spars.

I also rounded out the base of all of them that would be attached to a spar, so that they are seated well.

20210825_163749
20210826_175349

I also made a copper 6 gauge wire lock for the boomkin brace.

20210826_181138

It rained for a couple days so I moved all the varnishing inside and kept the fan running to help the drying process.

20210827_122509

I’ve also been holding on to pre-1996 pennies that have a high copper content for precisely this use. It is kind of fun to put in some centennial pennies somewhere were they will continue to be admired.

20210827_151926
20210827_151941

Then onto making rope strops for the blocs while I wait for the varnish to dry.

20210827_163736
20210827_170941

This was a super satisfying moment to see this come together into fully functional blocks. This fiddle block with two eyes was the most complex of them all.

20210827_162418

The dyneema is easy to work with and is so stiff that getting everything snug and tight was relatively easy.

20210827_185301

I have home made, blocks for the main, jib and mizzen as well as the jib halyard.

Today is the eve of my self imposed launch deadline. So I also started doing all the leathering on the spars.

20210828_204014

Tomorrow will be a full day preparing for the launch at the Jericho Sailing Centre. My hope is to be ready by 4pm. I still have to splice the eyes for the halyards, the gaff span and leather the mizzen and boomkin. Then I think the last job will be lashing the sails on and running all the halyards and sheets.

20210828_192817
still a little work to do, but almost ready.

caledonia yawl project: spar building part VII

Progress, progress, progress… it still feels too slow but at the same time it is nice to see things I thought about in advance come into play.

20210824_142125

I had the 6 gauge copper wire for several months and it is quite satisfying to see it work nicely with the home made roves.

20210824_142143

I also did the final shaping of the inside of the jaws with a half round file. In hindsight it would have been better to cut out a semi circle from the but of the spar before gluing and advancing the wedges a little too. But although it took a little more work I think it looks fine.

I finally applied the first coat of Epifanes clear varnish mixed with 50% brushing thinner so that it penetrates into the wood as much as possible.

20210824_172945

It is such a satisfying feeling to finally stop sanding and apply the finish to the wood. I did realize that I had not completed all the little thumb cleats that need to be added to the spars and will need to be varnished. So I started on that this afternoon. I’ll keep at it tomorrow morning so that the next coats also cover the cleats as well.

Caledonia Yawl Project: Spar Building part VI

The boom and the yard come second only to the birds-mouth mast in complexity. The jaws required some attention to detail.

20210818_135729
shaping the yard

The process of going from a square piece of glued up wood to a tapered cylinder is now becoming familiar. But there are still individual particularities to each piece as you have to read the wood and each facet might require planing in a different direction to avoid grain pull out.

20210818_150236

I started to decorate the place with the draw-knife cuttings which are so much fun when they are the full length of the spar.

20210819_105628

Careful mapping of the facets when you get from 16 sided to 32 sided is worthwhile. I found that marking the 32 edges then helped me keep track of where I was when I cut it down to 64 sides. On the yard that ends up being just one or two passes with the planer set very fine. It is in my mind the trickiest part of the process.

20210820_154227

After sanding the yard with 36, 60, 80, 100 and 120 grit sandpaper I was onto the boom. The time spent making this spar gauge based on Harry Bryan’s design in Wooden Boat magazine 277 was worth it but it was kind of bittersweet to think this was one of the last times I’d use it for awhile. (note: I still might use it to make the oars)

20210821_183027

The jaws require a transition from round to square which is an extra challenge when shaping the spar. In the end once marked it is relatively easy to do.

20210820_103950

I still have some of the reclaimed Honduran mahogany that was pulled out of home demolitions by a renovation contractor who was retiring and selling off their stockpile of old window and door frames. I now wish I’d bought more for future projects. But for this project I have enough.

20210820_114026

As per Ian Oughtred’s plans he specifies the jaws should be 22mm thick and made of two pieces. I added a 5mm marine ply to the mahogany to get to 25mm and it will do well to reduce the chances of splitting along the grain on this curved piece.

20210821_170043

I’m also attempting to make some copper rivets according to the September 2015 Small Boats Monthly article by Christopher Cunningham for the yard and boom jaws. I was able to order #6 gauge copper wire and I’m using some leftover 1/2″ copper pipe for the roves.

20210823_135331

Then shaping the pieces into something that looks relatively nice. I used the Japanese rasp, the block plane, the spoke shave, the belt sander and the random orbital sander to get it into it’s desired shape.

20210823_163711

The boom and yard jaws dry fitted.

20210823_182801

… and then all glued up. Tomorrow I’ll do the final shaping on the yard and boom and some sanding of the epoxy. All the spars will get sanded down to 150 grit tomorrow and all set up for varnishing. I’ve also got a bunch of little fittings to make that will need to be screwed onto the spars. Most are just little thumb blocks, but I also have to make the jib fairleads. I’m getting close to being able to rig it all up.
