Seakeeper 16 – Gyrostabilizer For 55–70 ft Boats – For Sale

The Seakeeper 16 enters the large vessel gyrostabilizer category — delivering up to 95% roll reduction for the 55 to 70-foot class of large motoryachts, serious offshore sportfishing vessels, and high-end custom cruising platforms where stabilization is a standard feature expectation among buyers and owners. This Seakeeper 16 gyrostabilizer for sale weighs 880 lbs and provides the flywheel mass and angular momentum required to counteract the rolling forces generated by the large displacements, wide beams, and high freeboard typical of 55 to 70-foot vessels — boats where beam sea rolling in moderate offshore conditions can generate 15 to 25 degrees of roll amplitude that makes normal on-deck activity and interior function genuinely difficult.

At the 55 to 70-foot vessel size, the Seakeeper 16 is not a luxury upgrade — it is the standard of the market. Buyers and charterers of vessels in this category routinely specify Seakeeper as a condition of purchase or charter booking, and professional captains consistently cite roll elimination as the single upgrade that most improves crew efficiency, guest experience, and the operational envelope of the vessel. The Seakeeper 16’s no-external-appendage design means zero drag, zero maintenance for external stabilizer hardware, and no risk of appendage damage in shallow anchorages or during dock approaches — advantages that are particularly valuable on large vessels where any off-season haul-out for appendage repair represents significant cost and schedule disruption.
