Thanks Brian and Bill,

This is what I have now for frame 4:

I haven't cut the frame interiors yet so I can play around with the shaping a little there. I like the idea of making a masik
for the upper span. I have some nice clear spruce 1 inch thick that I could use for that. Perhaps if I epoxied that to the front
of the frame and shaped/beveled it? It would be nice to perhaps cut the upper span off from the ply form and just use a
real masik as Bill suggests. I wonder if it would be prone to splitting along the grain with that much curvature and the grain
running across the cockpit? I could glue two pieces of 1 inch spruce together to get a two inch thick masik. Bill are you using a
solid masik, or laminating, or something else?

I could flatten the interior of the upper span a little too as Brian suggests. That would reduce the legroom. Perhaps the
outline I have now might be Ok? I've not tried to sit in a boat this tight before so I'm tending to think I'll leave it a little
more open and pad it out with a little minicel foam if I decide it is too loose?

Shearwater 16 is the closest thing to this that I paddle. And that is downright roomy inside by comparison:)
