Gemini Freestyle 399 Power Power Catamarans For Sale

The Gemini Freestyle 399 Power is a power catamaran derived from Gemini’s Freestyle 37 sailing-design lineage and built in the United States. Listings describe a center‑console layout that reconfigures the Freestyle 37 concept into a powered dayboat, retaining the catamaran characteristics of wide beam and shallow draft while adding outboard propulsion and redesigned bows.

Accommodation on the Freestyle 399 Power is compact and purpose‑driven: a one‑bed, one‑bath arrangement is cited, with a deliberately spacious forward deck intended for sight‑seeing and increased usable cockpit room resulting from the forward, center‑mounted helm. The helm placement up front and center is presented as a design choice to open the cockpit and improve sight lines for helming and social use.

Propulsion and reported performance figures vary by source and configuration. Several listings indicate a typical cruising speed in the 14–15 knot range. Reported top speeds span a range—listings reference bursts up to 18 knots, a documented high of 21 knots, and a separate report of 22.5 knots at wide‑open throttle with seven persons aboard. One listing identifies the test powerplant as twin Suzuki DF90A outboards; other listings reference upgraded outboards generally. These figures should be interpreted as reported values dependent on engine fit, load and sea state.

Hull and appendage details highlighted in the listings include aft‑mounted stability keels and bow extensions intended to lift the hulls as the boat accelerates. The shallow draft is quoted as approximately 18 inches, a characteristic consistent with catamaran designs that operate in shoal water and anchorages where draft is a limiting factor.

Across listings the Freestyle 399 Power is positioned for day‑boat use, cruising and day charter operations. Broker and manufacturer descriptions emphasize the combination of catamaran stability and increased speed capability compared with its sailing antecedent, noting a steady, balanced ride as a frequently mentioned attribute of the design.
