  • Anchor chain lock and samson post adjacent to the anchor winch.
  • A moderate-size sail locker to stow ‘off-the-wind sails,’ warps, sheets, and other equipment.
  • Integral gunwales, specifically designed to allow isolated stanchion attachment.
Hull Design:

The Samoa 56 features a single-chine hull with fair and rounded underwater lines, ensuring smooth sailing and optimized hydrodynamics. With a near-plumb bow and integral bow sprit, the design maximizes waterline length for increased performance.

The moderate-to-wide beam enhances cockpit space, internal volume, and downwind efficiency.

A retractable bow thruster improves maneuverability, while a variable-draft system offers versatility in different sailing conditions.
