Next came the test fitting of the second strake, and the beveling of the outer edge of the garboard. I ended up using a borrowed power planer. On this beveled edge I nailed and glued the second strake (third photo). The fit at the stem was not great, due to the problems with the height of the stem I mentioned earlier: it seems that the top of the stem moved back up about a centimeter as I was building the skeleton. I think that there is enough strake overlap to correct the problem as I put the other two strakes on. I will need to plane the upper edges of each strake (they are not perfect) and fill the lap angle with epoxy compound for strength.
This is the account of an amateur's hand-building a 15-foot open sail- and row-boat, from original design to crafting the traditional rigging and sewing the sails. Always a glutton for punishment, I am building a similar one in Greece. (Για πληροφοριίες στα Ελληνικά, επισκεφτείτε http://tarsanas.blogspot.com)

Garboard and second strake
The next step was to lay on the garboards (bottom pieces). After cutting off 6mm from the inner edge in the middle to accommodate the extra thickness of the centerboard trunk, and a little trimming, I test fitted them. Considering that my cuts were not particularly precise, the fit was decent. Since I am planning to fillet the seam between garboard and keel, the small gaps will be filled with epoxy compound anyway and the final product will be stronger for it. It's already starting to look like a boat, sort of.

Garboard
This being a long weekend and my wife being away to take care of her sick mother, I thought I'd try to make a lot of progress. So I am happy to report some. I put on the keelson and then beveled it to take the bottom pieces. I call them garboards, which is the common term for the first pieces (next to the keel) that go on when building a lapstrake boat upside down, but I wonder if that applies to a design with only four strakes per side. Beveling a 13 foot 1X4 board to an 8 degree angle takes a lot of planing and sanding, and as you can see the garage looks like a nest of pet rabbits from the shavings. Another look of the keelson and the centrerboard case on the right.Then I took the plunge and cut the garboards (aka Strake 1). I did not trust the design program and/or my own measuring and cutting skills, so I decided not to join two 4X8 plywood sheets, then cut the pieces (not enough room anyway). So I cut the two halves separately, fit them (they were fine), then scarfed them. I have to say that sanding is very far from my favorite activity, so I did not enjoy the scarfing, nor was it a particularly good job, but it will do (see on left).
So today was the time to commit to glue and nails. First I had to cut a slot for the centerboard, which turned out surprisingly easy (even though I had to set the blade of the circular saw at 8 degrees). Then I coated surfaces with epoxy, mixed more epoxy with wood flour, slathered the goo on all the joints, and nailed on the garboards, using bronze ringshank nails. I will have to set the nails and putty the indentations, but for now let's admire the putative boat, which is looking more like a boat every day. See also the close-up of the bottom, with the off-center centerboard slot.By the way, if I hadn't forgotten what a pain it is working with epoxy (sticky, messy, ruins brushes, coats tools, needs a respirator which is hot, sweaty and awkward, leaves black rings around fingernails, etc.) maybe I wouldn't have started. But now I am committed, so keep reading 176inches.
