Hey MIke:
Your comment about the NE canyons got me thinking - part of our fishery is the 10 hour night drift in Sept in sometimes less than pleasant sea conditions.
What sort of thought have you given to roll and pitch control during those long and sloppy nights.
I use this

and a drift sock on a 28' on sloppy evenings and it does a tolerable job of dampening pitch and roll.
If you haven't already given it thought you might want to think about how to design in a solution as part of the final fit out.
