The singlehander can tuck a tiller between his legs, freeing up both hands for raising the sails and tacking and jibing maneuvers. This interior layout has no tricks or angles, just good common sense application of space. The head can be enclosed and is quite large. The only hanging locker I see is outboard of the w.c., and I think this design would benefit from a dedicated wet locker to starboard instead of a second sink. Stowing wet gear on a small cruiser is a tough problem.
Wet gear needs to have air circulation if it is to have any chance of drying.
In Seattle this is important. Two sinks on a boat this size is too luxurious a use of space. This interior will have a good feel to it. It will feel like a boat. There is also a 20-gallon fuel tank.
