Shipyard photo – model image, not a specific boat.

What distinguishes the model

  • The wide hulls create an exceptionally large living volume with the galley up and plenty of space for long stays on board.
  • All lines lead back to the protected helm station, which makes sailing double-handed and even single-handed pleasantly simple.
