Deck Layout

Hatseflats will have

  • bow and transom tanks for buoyancy, storage, structural support.
  • the transom tank provides a seat for the helmsman
  • the daggerboard case combines with a rowing thwart

I will not have side tanks like the Mirror dinghy because when capsized, the hull will be too high in the water and blow away downwind. Also the side tanks are a bit narrow to sit comfortably for long hours.

I may have removable side seats, like the 15' Drascombe Peterboat (note that the similar Drascombe Scaffie has side tanks, but is 25cm wider). Ross Lillistone, designer of the 15' Phoenix III argues that in small open boats the best place is on the floorboards with your back against the sides. That way you are protected from the wind and spray. And your weight is in a better position than when sitting on a deck leaning against a coaming. He proposes to have movable side-seats which make a sleeping platform for one. See blog article by Ross Lillistone.

For now I will have removable side seats like the original Peterboat. Either 2x10mm ply (easy) or 10mm with wooden rails for light weight and stiffness.
