Seakeeper 5 – Gyrostabilizer For 35–50 ft Boats — For Sale

The Seakeeper 5 enters Seakeeper’s mid-range gyrostabilizer category — delivering up to 95% roll reduction for vessels in the 35 to 50-foot range where the combination of significant offshore capability, substantial beam, and frequent extended cruising makes roll elimination a high-priority investment. This Seakeeper 5 gyrostabilizer for sale at 335 lbs provides the gyroscopic mass required to counteract the rolling forces generated by the heavier displacement and wider beam of the 35 to 50-foot boat class — motoryachts, large offshore sportfishers, and twin or triple-engine express cruisers where passengers spend extended time at sea and where the difference between a comfortable passage and an exhausting one is measured entirely by how much the boat rolls.

At 35 to 50 feet, vessels are typically crossing longer stretches of open water on a regular basis — offshore anglers running to the Gulf Stream, cruisers transiting between major East Coast ports, and recreational boaters exploring the Bahamas, Caribbean, and other offshore destinations where beam seas are the norm and rolling is constant. In these conditions, the Seakeeper 5’s 95% roll reduction is not merely a comfort upgrade — it is a safety upgrade that reduces fatigue, prevents seasickness, keeps crew and passengers safe on deck, and enables the crew to perform tasks that would be dangerous or impossible on a rolling boat. The no-external-appendage design means the Seakeeper 5 adds zero drag to a hull category where fuel efficiency over long offshore passages is a significant operational concern.

The Seakeeper 5 is in stock at Boat Engine LLC — New York’s authorized Seakeeper dealer — and ships to all fifty states and to international destinations worldwide.
