Basic Hull pieces / The sheer strake

 Here's my computer drawing.  Many of the pieces are not drawn exactly, but it lets me view it in three dimensions to see what changes might look like.

 Here's the basic hull pieces.  The frames, sides, and first bottom panel.  These are the pieces that will be 'stitched' together when the hull first gets assembled.

 This is a simplified drawing of the basic hull pieces.  The frames in brown.  The two bottom panel layers in blue, and the sides in yellow.  There is also the 'sheer strake' in green.

The sheer strake goes along the top of the sides and visually is what gives the boat's profile view its graceful look.  In this construction it also makes the top 6 inches of the side panels a double thickness.
