Cool. I always wanted a Samson Post. I wonder if it would tend to snag the jib sheet when tacking?
The two additional cleats up forward may be over-kill. They would also be going through cored deck. Might want to beef up the deck from underneath if they're going to get hard use. You'll see how Pearson glassed in a piece of wood on centerline for the cleat.
Chocks. Some of them are real line-cutters. The ones they sell all seem to have fairly sharp edges. I'd like to see them more rounded on the inside.
Seems to me that boats rarely get loose because the deck hardware fails, or the rope is to weak. Its always chafe cutting the line.
