John, congrats on a beautiful kayak (I almost wrote boat ;-) and I am glad you like the way it behaves.

But a comment – you write:"Cockpit- Bjorn Thomasson specs a small cockpit, and the seat is located 'right back' in the cockpit. (My back is about 2-3" from the cockpit rim, vs 4-5" in my other boats. I can feel the difference in the neoprene sprayskirt.)"
The suggested seat on the plans is an integrated bulkhead/seat structure (which has become my absolute favorite configuration, used in all my recent kayaks), where the aft edge of the seat part is indicated to be 8 cm (a little more than 3") from the rim. With the low aft deck/rim it means that the geometry when leaning back on the aft deck is approx the same as in the usual brit boat with their higher deck and 4-5" distance. But moving the seat an inch or so forward to match brit style spraydecks would have very little effect on the longitudinal balance and behavior (given a rather high Cp).
