About the GUNBOAT 66

Sailpages Buyer's Take

The Gunboat 66 is a high-performance offshore cruiser designed by Morelli & Melvin and built by Gunboat, with production records indicating a start year of 2007 and an unspecified total hull count. This vessel combines a fractional sloop rig with a variable keel configuration, offering a displacement of 34000.0 lb and a beam of 28.16 ft, positioning it as a serious tool for long-range cruising.

Best for:
This boat is best suited for experienced bluewater cruisers and offshore racers who prioritize speed and self-sufficiency, as evidenced by the high prevalence of watermakers, solar panels, and bow thrusters in owner reports.
Bluewater capability:
With a capsize ratio of 3.48 and a comfort ratio of 9.77, the Gunboat 66 demonstrates strong offshore stability and seakeeping characteristics, supported by owner reports of extensive bluewater equipment installations.
Comparables:
Comparable vessels include other high-performance offshore cruisers from the late 2000s such as the Swan 651 or O'Day 40, though the Gunboat 66 distinguishes itself with its wider beam and heavier displacement for enhanced stability and storage.
