Gunboat 66 Buyer's Guide
Shopping the brokerage market for a Gunboat 66 means entering the world of the all-carbon cruising catamaran that Gunboat International launched in 2007 — a 66-foot Morrelli & Melvin design with twin 55hp Volvo Penta diesels, a 1,200 amp-hour lithium system, and a fully enclosed bridge-deck saloon. These are performance cruisers built to sail 300 miles or more in a day, and the used fleet reflects both private and former-charter histories. Knowing the standard structure and the few documented caveats helps a buyer focus a survey.
Layouts on the Used Market
Charter four-cabin layouts are the more common on the used market, but both are available; ex-charter examples are common. The standard accommodation plan provides four queen-sized cabins each with an ensuite head and shower, plus dedicated crew quarters with their own ensuite, and the saloon carries a large settee, folding dinette, forward-looking nav and helm station, and spacious galley. The accommodation plan is fully customizable, so private boats may show owner-directed deviations, but Gunboat does not like to move structural bulkheads. Headroom is 6 feet 5 inches and berths run 6 feet 7 inches by 5 feet in the forward and aft cabins.
Equipment and Common Upgrades
On the used fleet, a watermaker, solar, and lithium batteries are commonly fitted. The boat’s standard equipment already incorporates AC/heater units, gen sets, watermakers, and entertainment systems, and the nets and lifelines are Spectra. Some 66s are fitted with a second, stern-facing wheel in the working cockpit, an item to verify rather than assume. The standard 1,200 amp-hour lithium ion electrical system aligns with the commonly fitted lithium tier, but solar and watermaker presence should be confirmed per boat.
What to Inspect
The documented known issue on the Gunboat 66 is narrowly scoped: reviewers noted she is expensive, which frames but does not describe a defect. No structural or systems defects beyond that single observation appear in the survey record, so a buyer’s survey should instead confirm the integrity of the carbon composite specifics the builder documents — the monocoque laminated deck joint with no evident flange, the vacuum-bagged and post-cured bulkheads, and the independent watertight bilge areas with collision bulkheads. Given the builder’s stance that structural bulkheads are not moved, any refit altering them warrants expert review.
Availability and Buyer's Takeaway
Typical markets for the Gunboat 66 are Spain and Puerto Rico. For a shopper, the takeaway is a short checklist: confirm whether the example is ex-charter and which layout it carries; verify commonly fitted gear — watermaker, solar, lithium — is present and functional; check for the optional stern-facing working-cockpit wheel; and have a carbon-composite specialist assess the deck joint, bulkhead tabs, and watertight subdivisions. The 66 rewards the prepared buyer with a uniquely capable enclosed-salon cruiser.
