CALEDONIA yAWL pROJECT: sUMMER DETAILING

I’ve been moving along motivated to complete the boat in 2020. As things are with projects like this the desire to call things “good enough” is tempered with the awareness is that a “an ounce of prevention is worth a pound of cure”. For example spending the time to drill the screw holes oversized and then fill them with thickened epoxy and then re-drill them to the appropriate size again.

We’ve tested the Norwegian tiller and report that it appears satisfactory

I also finished shaping the chocks out of reclaimed local cherry wood I’d been seasoning.

The next step was doing things I’ve been putting off as they are simply put dramatic. Cutting the hole in the motor well was one of those things I considered not doing until I actually bought a motor. But it would have then become a space that collects water and it would be harder to do well once out of the shop. So I made the call modelling my hole on the space needed for a Torqueedo 1003CL which is the motor I’d like to be able to use. The electric motor takes up much more room than the gas motors so I figure it will be plenty large if for some reason I decide to use a four-stroke engine instead of electric. I used a small drill bit to get started and then finished with a small keyhole pull saw which worked very well.

I was then ready to star pulling out the protective coverings. Starting with all the surfaces that will get the Deks Olje. The idea being that if I go over with paint later, It will be easier to wipe clean rather than when it seeps into the pores of fresh wood.

I also created the plug for the motor well that fits onto a backing plate and will keep the hull flush and fast when sailing.

20200613_153538

I then tackled the interior of the hull. Removing all the floor boards, thwarts and benches.

20200626_203319
Priming felt amazing, I really felt I was reaching a milestone.

Before painting the foils and the hatch covers, I did a final fitting of the centreboard in the boat. I had been satisfied the last time I tested it. But today I found that mostly due to the way I had finished the tip with a generous extra roundover of expoxy, it was a little too long. So I cut off the tip and removed a 7mm strip.

20200726_121659
Small strip of centreboard removed. Shows good shape and construction method.
20200726_120656

I then reglued the tip to the centreboard. This shortens it by just shy of a cm and also provides a protective water break in the centreboard. That way if by chance I nick the tip on a submerged object, it won’t wick up the cedar grain that is at the core of the centreboard and rot.

I had chosen the teal colour I used below the waterline to be used in the interior as well because I really like the contrast with the colour of varnished wood. Thought while applying the alkyd enamel up close I started to wonder if it is too punchy. I’ll finish applying the first coat to the whole boat and remind myself that the benches, thwarts and floorboards will obscure a lot of what is currently visible.

Caledonia Yawl Project: fitting out the interior

The fitting out of the interior to get it ready for painting continues. I’ve been adding all the fittings to make it possible to have removable floors.

20200418_112929
Adding a cleat to the bulkhead to hold the bow floors down
20200425_133248
all glued up.

Adding little wedges to finish the bow inner and outer stem pieces.

20200418_112946

Cutting out the reclaimed cherry to make the boomkin brace

20200426_120012

And then deciding whether to place it at the bulkhead or further back? to interfere less with the motor well.

20200502_183613
20200502_183630

Then I tackled the bow chocks out of pieces of cheery from the neighbourhood that I had been seasoning for a while.

20200502_232923

This was a very satisfying sculpting of wood. The cherry is hard but quite nice to work with.

20200502_232952

I’ve also built a backing plate for the motor well to have something to glue the piece of hull I will cut out to so that when sailing we can still have a nice smooth hull.

20200426_132421

The next step that has been slow going but necessary work is creating the hold-down tabs for the floors.

20200509_132653

I’m using leftover brass keel strip 1/2 rounds and small pieces of reclaimed mahogany as risers.

20200511_215845
20200518_142944
20200518_150053

I had to glue a couple extra pieces to the floors to allow for the adequate spacing of the hold-down cleats.

20200517_143343
20200517_143350

I’ve also been spending extra time drilling oversized holes for the screws and then filling them with epoxy into which I will then set the screws. This will help prevent moisture entering the wood through the screw holes. I think this is especially important on all the horizontal surfaces where rain water might trickle down.

20200524_144346
20200517_143356

I’ve also shaped the tiller arm

20200522_174642

And cut the mortise in the rudder head

20200522_185827

It took a while but eventually it all fit nice and snugly.

20200522_194314

I even did the little wedge out of a small piece of mahogany

20200522_205159

The eye for the eventual reaching sail is now attached to the bow.

20200524_152917

I’ve also started on a pair of chocks for the stern. They will allow for stern tying to the beach or a shoreline and to tie the boat to a dock.

20200524_150353

Now i’m all caught up. with the last month and a half of work on the boat. I’m motivated to get done before summer gets underway. Once the floor cleat risers are glued. I’ll be ready to start prepping the hull for painting. I’ll start with doing all the parts that will have Decks Olje. The gunwhales, the mahogany trim and the cherry chocks. The rest will all be painted teal or white.

Caledonia yawl project: the floors, odds & ends

The cross country ski season has come to an abrupt stop with the closure of the local mountain trails due to the Covid-19 pandemic. It is unfortunate as March has seen considerable new snow and what I imagine is great conditions. That said it is imperative to self isolate and maintain physical distancing to control the spread of the virus.

My adaptation in Vancouver to stay active is to make a small investment in roller skis to keep the technique sharp and to do much more running. Now that we are working from home, I’ve replaced my bike commute time with morning runs. It helps to create a sense of separation from the home and the work even though they are take place in the same place now. In reality it is a struggle to discern what time is for what. Is it homeschooling hour? work hour? personal development and reading or the general tending to domestic needs?

With all that I’m endeavouring to find moments to return to the boat which is providing as always a place and time of quiet meditation, applied problem solving and creative output.

Here is a rundown of the discrete projects I’ve tackled on the boat.

Building the mizzen mast collar on the aft deck.

20200215_190255
Collar cut out of two pieces of 9mm okoume plywood
20200316_085118
Glued down with a groove between the two pieces to enable a mast boot to be connected.

The next item was the boomkin brace or hole that goes though the sheer strake. This is one of the scary items where positioning and aligning is important to that the boomkin end is aligned with the centerline to sheed the mizzen sail. The other consideration is the rudder head and making sure there is no impeding the rudder swing (a good reason to do the rudder earlier in the build process)

20200229_151132
I got a 1′ long drill bit for the hole saw to help with alignment and cutting on an angle.

and away we go.

20200229_151237

The angle is sharp enough that I had to cut from both sides.

20200229_151531

I then cut the remaining tabs with a needle width pull saw. Then I reproduced the angle of the cut on a piece of 1″ thick mahogany board.

20200229_154334

which I then cut out as a frame for the brace and cut that in half (delicate operation with a pull saw) to be able to have the frame on each side of the hole.

20200229_170805

This was a challenging glue up shape the clamps just did not work. So in the end I used small 3/4″ copper ring nails to hold it down during the glue up. I like the look of it so they will remain in place.

20200319_172108

I also took a leap and cut the shape of the bow and stern stems. I’d been holding off as I’d waffled on having a more flat profile or the curved profile Ian Oughtred also puts in the plans.

20200314_164728_001

I’ve decided on the curved profile and I’ll add this bronze bow eye that will be used for as a secondary forestay location or to attached an eventual jennecker. The normal pad eye for the foresday will be just behind the the bow brace on the deck.

20200314_180342

And the stern stem cut to rough shape

20200229_182107

That is the first part of this COVID-19 boatshop isolation chronicle.

Caledonia yawl project: deck hatches

The winter has been full of distractions, but I’m trying to keep the momentum going. Since getting the Sitka spruce I’ve been focused on finishing the hatches on the bow and stern. It is one of the few things left before I can paint the inside of the hull.

20190923_173637

I decided to give the deck a frame that is proud by just 1.5cm

20190930_221527

I built up the hatch covers in three parts. An inner frame, a cover and an outer frame.

Caledonia yawl project: shopping for Sitka spruce

Sitka spruce is the preferred wood for spars, due to its excellent strength to weight ratio. Unfortunately there are fewer and fewer people and industries seeking out the wood. This means that even a place like Vancouver in close proximity to the forests that are home to the wood with legendary properties, it is hard to come by.

I’d almost resigned myself to the second choice of using good vertical grain Douglas fir for the spars. It is a bit heavier but just as strong.

Until this weekend when I found a small lot of 20′ beams for sale in Maple ridge.

20190923_113334

These are very nice quarter sawn pieces from good sized trees.

20190923_113340

But they are 6″x12″ so I’ll have them mill it into smaller pieces that I can handle on the table saw and prepare for the birsamouth construction for the main mast. The other spars will be made of two pieces laminated together to reduce the chance of warping.

CALEDONIA YAWL PROJECT: SUMMER PROGRESS

This summer was spent with 3 weeks away in France visiting family and friends. I was lucky enough to be able to get my fix of beautiful wooden boats in the port of Douarnenez.

20190601_183459
Gluing the rowlock riser out of small pieces of reclaimed mahogany

I’ve been lucky enough to have a few weeks where I was able to devote several weekends and evenings to the boat building. Although my progress has not been as quick as I’d hoped. My desire was to be finished for the labour day long weekend. But there is still so many things to do and I quickly realized that I was not in any position to keep to that desired deadline.

20190602_154532
Shaping the knees for the forward bulkhead

I shaped the forward and aft deck plywood to shape. It was tricky to scribe and cut just right. I was also pleased to see that the deck beams aligned nicely with fair curves.

20190727_170042

I then epoxied the underside as preparation for gluing them down.

20190728_140800

These are parts that will be hard to get to in the future. So I coated them in epoxy and painted them.

20190804_165511
Taped the deckbeam and kingplank for painting so that later I can glue the plywood to that unpainted surface.

Gluing down the decks and clamping with a mix of screws and clamps where possible
20190917_180526
My assistant made sure they still fit inside.

I did a nice fillet around the edge of the deck. The next step is to make the hatch covers. I will have a frame that protrudes so that water can’t seep through and into the bulkhead compartment. But Ideally it will be as low profile as possible. I’m thinking a 1cm fence on which the cover will rest. I think this will be preferable to a flush deck hatch which relies on a gasket to keep the water out.

20190917_180545
Looking forward to painting the rest of the interior soon

Caledonia Yawl Project: fitting out the hatches

The progress is now something that is not prescribed in the plans drawn up by Ian Oughtred. It is true that a flush and clean decking with a minimum amount of fittings would be more water tight. But already I can see that the bulkhead access ports won’t really be sufficient to get full use of the bow and stern compartments. So I’ve decided to add hatches to the deck in the bow and the stern. To make this as water tights as possible I’ve created frames before I start laying down the deck.

20190406_204105
Adjusting the rise of the kingplank on the bow to match the sheer strake lap with strake 6.

I also started fitting the decking make sure the kingplank and the deckbeams are flowing right. I found that the straight kingplank at the bow did not match the upward flow of the sheer strake. At first this scared me as it introduces a compound curve for the plywood decking. But in trying it out because the plywood is in two pieces and gets quite narrow at the bow it won’t be too hard to torture it to follow the curve.

20190406_205511

Then I got to the framing of the hatch framing. You will notice that they are intentionally trapezoids. It just looked too weird when I mocked it up as square.

20190413_194130

I then turned to the fitting of hardware. With the arrival of 4″ 5/16″ bronze bolts for the chainplates I got to work drilling the holes in the beautiful bronze castings from Classic Marine. (I bought them a while ago and feel like it was as we say in french “un petit caprice” especially now that I see the price of bronze has gone up further)

20190511_174344
Drilling the chainplates

Once complete they are now ready to have the hull and frame drilled too.

20190511_181250
Chainplate all ready to be fastened

The stern hatch frame was completed and a few other beams added to support the plywood decking for good measure as I know I will have children running up onto all surfaces of the boat.

20190511_200645

The next steps involve fastening all the benches, thwarts and knees and then removing them before priming and painting the whole interior.

I will also go get some 1×4 of 1×6 cedar planks to use for the floor. My plan is to leave it unfinished as a sacrificial surface that I plan to leave raw.

Caledonia yawl project: winter progress

The winter has been productive but still requires working around cold days where it gets tricky to create conditions to be able to get the epoxy to cure.  This winter was also an active year with every sunday dedicated to coaching nordic skiing with the Hollyburn cross country club with my children.

Here is a summary of the activity this winter :

20181214_121743

I bought sunbrella fabric at Dressew for the boat cover.

20181228_163250

And over the Christmas break, with my friend Patrice we did a lot of sewing on his Sailrite sewing machine.

20181226_124602

20181223_141809

I finished carving the first set of eight cleats made of the reclaimed backyard cherry tree from a couple blocks away. I also used Deks Olje D1 and D2. They came out looking great and I look forward to installing them.

20190101_220114

More Deks Olje on the centreboard well capping. This wood is reclaimed mahogany from door and window framing in Vancouver. It must be quite old, but looks fantastic.

20190113_180758

I installed the aft deck beams and king plank. After struggling a little with the geometry of the bow, I had an easier time in the back… except that this time the deck beams land between the laps and so tracing the fair line for the edge of the aft deck was still a little challenging.

20190119_162714

More Deks Olje on the centre thart. Also made of reclaimed mahogany.

20190127_163256

Adding the extra bracing to the king plank to allow for a hole to be drilled for the mizzen mast. It is glued to the aft stem and to the aft deck  beam.

20190205_192035

I had the foresight of ordering the sails over the winter when the sail lofts are maybe a little less busy than in the spring. I ended having them made from the local loft of Evolution Sails in East Vancouver. The bonus is their loft is right above Andina Brewing.  So far I’m really pleased with the way that they turned out. The real test will come when the get laced up to the spars for the first time.

20190209_211029

Then to complete the aft compartment I installed the motor well.

20190216_211610

This was a somewhat tricky to glue up and in the end looks pretty solid.  The only thing I’ve not done yet is cut out the hole out the bottom. That is going to be the weirdest part. I might have to put the boat on its side to do that because I can’t fit the jig-saw in from above.

20190218_134858

My trusty assistant came in on one weekend to help with the surface preparations and testing out all the dimensions.

20190218_142502

20190317_162213

Then I had fun with cardboard templates trying to get the shape and geometry of the bench braces just right. It is tricky because you need the benches in place to know where the edges of the bench as well as the height of the bench.

20190325_092753

I then returned to a half finished project that I had started earlier and carved out the rowlock risers from more off cuts of reclaimed mahogany. These will look really nice with the Deks Olje soon.

20190324_193241

20190325_093018

I struggled with the drain plug installation. Since the garboard planks are just 9mm (1/2″) there is not much wood for the screws to bite into. I thought of through bolting the bronze drain plugs but that is also problematic. So I finally took a few ends of 9mm marine plywood and made these risers that I then glued onto the garboard on the inside of the hull. The drain plugs will then be bedded and screwed on with #6 bronze 1/2 or 5/8 screws.

20190401_185838

Finally a good Craigslist find, a new set of bronze oarlocks and the not yet installed leather ready for my as of yet not yet made oars.

My plan is to make them 11′ long with a scarfed coupling as described in Wooden Boat 229 by Harry Bryan for a sculling oar. I think that if it works it will allow me to have oars long enough for a boat with this wide a beam. By being able to separate the oars into a 5′ and a 6′ section, they will me much easier to stow and lash down below the benches. I’ve got some pieced of 1/2″ and 3/8″ half round brass keel rub strip that I think I can use for this.

The Caledonia Yawl Project: mast steps and cleats

Before I start the aft bulkhead, I realized that I need to complete all the fittings that will be enclosed in there. That means that the mast step for the mizzen mast as well as the through bolts for the gudgeons that will hold the rudder pintles. 

20181023_192943
cutting the mortise for the mast step


I used the same process I used for the bow brace for the forestay padeye.
A wedge that is shaped the match the curve of the inner stem with two cheeks make of marine ply scraps that will be epoxied to the inner stem.

20181023_214925
Completed mizzen mast-step ready to be installed

I also threaded two bronze rods on either side of the step to prevent the wood from splitting. And screwed two weeping holes on either side should water make it down the mast. I think this little construction is pretty bomber.

20181024_191341
All ready for final positioning

I then turned my attention to the main mast step. For this I took a piece of cherry that I had chainsawed into slabs from a local tree that was cut up and put out for free. It seasoned for two years under the boat.

20181103_192032
Main mast step mortise

More to come on the main mast step as I am working on a solution for the drainage from the forward compartment.

20181111_124433
Tracing the cleat outline with my helper

Since I had started to mill the cherry slabs for the mast step, I decided to keep on going and cut it up into appropriate sizes for cleats , chocks and other small rigging parts. We cut it on a table saw into slabs that were 1 1/8″ thick and started to trace the templates I got from the Curly Shavings blog who had created a PDF file with a nice sensible outline. By playing with the size of the printing I could create a template for a smaller and a larger cleat. 

20181111_124509
20181111_133712
Ready to be cut

I had access to a drill press so I did that part. I’ll borrow a band saw soon.

20181111_144212
20181111_154834
First cut, with a jigsaw to complete the proof of concept

Lots more shaping to do. The cherry is proving to be solid, easy to shape and fun to work with. Hopefully it will hold up well over time. My plan is to shape them all down and then have them well oiled. That should be easy to maintain if I keep on top of it.

Caledonia Yawl Project: Installing the knees to the thwart

My next step for the forward compartment was to glue in the perimeter batten to hold the edges of the deck. I used small ribbed copper nails to hold down the battens in place while the epoxy set.

20181007_183828

I will leave the copper nails in as they won’t rust and won’t do any harm.

Then on to the knees that I had laminated a while ago, while I was in a laminating mode with the stems. I had enough off cuts of fir laminating stock to do the knees at that time. But since I’d just run the through the thickness planer when I had rented one for another task.

20181013_184935

The knees were first smoothed with the 1/4 round over bit of the router. That all worked mostly well except on one outer corner of the curve where the wood likely under tension ripped out with the router. I had to then glue the ripped section back down and sand it smooth.  To fit the knees instead of doing a template, I first cut the base angle and then scribed the right angles cuts to fit it to the inner gunwhale. When I made that cut I was a little conservative and I had the plane it down a few times to get it to fit snugly. I then used one side as the template for the other side and it went much faster.

20181013_192835

I’m now just going to do a touch more sanding before I get on to coating it all with Decks Olje. A two part oil finish that creates an fairly easy to refinish gloss coating. I like the rich clear finish it gives. Since I’m not planning on having too much material with a clear finish (Gunwhale, knees, thwart, Centreboard caps and bulkhead trim) I’m not too fussed about the cost. (nearly one third more than the cost of Cetol Natural Teak finish or most varnishes).  I have hesitated with my final choice for a while but ultimately decided to give Decks Olje a shot because of the penetrating oil of part 1 and the ease of touching up. In theory if you keep on top of it you could just touch up abrasions indefinitely without having to strip it all down as you would with varnish. Time will tell if I’m happy with it.
