And progress continues, albeit slow. The hull was turned last weekend, and I began filleting the interior joints for the buoyancy compartments using West 105 and colloidal silica for the fillets. I wear a good mask for mixing, the powder scares me.  

I'm going to have to decrease the width of the oar loom, to fit the design slot.:)
I've also added the seat battens. I found that at the specified size of 20 mm x 30 mm battens, the macrocarpa timber I am using is too stiff to bend to the curve, and was distorting the shape of the hull, as well as failing to form a tight match to the hull planks. So I have cut 10 mm x 30 mm strips, and laminated these into place, clamping them in place with home made long reach clamps.

I also noted that the batten top surfaces were not aligned with the seat plane, because the main face is clamped to the plank, which is at an angle to the seat. So I set the battens proud then planed down to match the angle, using a tell tale batten and an antique shoulder plane I found in an antique shop several years ago in Sydney (its the little black thing in the  photograph). Now the seat support battens are ready to receive the ply seats.
