The first boat bits

Finally, we started laying down the foam core planks.  Here you can see the first three pieces in the form frame for the float hulls.  We were just trying out the process, so nothing too dramatic, but it it is momentous occasion in any case.  I can already hear the waves lapping against the hulls, the wind racing past the jib and main, ...  Well, at least it's boat construction!

In any case, these pieces were heated for 7 minutes in the giant toaster oven, bent to fit the frame, and held in place with screws and 2" x 2" x 3/16" ply squares.  The general idea is to construct the hulls in halves with the split through the vertical axis.  The halves are joined later (much, much later at this rate).  The planking is done in the vertical direction, rather than the usual fore and aft planking.  This type of planking is typical for Farrier designs, and saves lots of glue joints.  I am planning to use 8" wide planks mostly, with some narrower planks at the ends.

Here you can see how the planks hold their form after they cool.  It only takes a few minutes for these 9 mm planks to cool.  They do retain some spring, but once they are joined, glassed, and have bulkheads installed, they should hold the designed form.
