A U.S.-built power catamaran engineered for 1,500-mile range, shoal-draft cruising, and genuinely off-grid living.
Few production power cats manage to blend efficiency, range, and shoal-draft versatility quite like the Maine Cat P-47. Willow, a 2011 example presented by Chuck d’Hemecourt of The Multihull Company, makes a compelling case for cruisers who want to travel far, quietly, and on their own schedule.
Range That Rewrites the Itinerary
Powered by twin Volvo D3 220-hp diesels, Willow cruises comfortably at 8 knots burning just 2.7 gallons per hour, or lifts to 18 knots when you want to log 150-plus miles in a day. With 400 gallons of fuel aboard, her theoretical range stretches to 1,500 nautical miles at best efficiency — enough that overnight passages become a preference rather than a necessity.
Salon and Helm
The salon feels bright and open, thanks to unusually large windows that wrap the pilothouse. There’s a fully equipped galley, generous seating, and the kind of counter and storage space that makes extended cruising livable. At the helm, Stidd fully adjustable chairs and 360-degree sightlines are backed by a full Garmin electronics suite, Volvo Penta electronic throttles, and Side-Power bow thruster controls — a setup that eases both blue-water passages and tight marina work.
Built for Off-Grid Cruising
Systems tell the story of a boat set up for real independence: a Northern Lights 6 kW generator, 640 watts of solar, a newly installed 24-volt 690 Ah lithium house bank, and Balmar 110-amp 24-volt alternators. Marvair AC with reverse-cycle heat keeps things comfortable in any latitude, and a Spectra 14 gph watermaker — rebuilt in 2025 — handles fresh water on demand.
The Multihull Advantage
Her 18-foot beam delivers stability and interior volume, while a 3-foot draft opens up anchorages most cruising boats can’t reach. Protected running gear, fresh bottom paint, and Prop Speed round out a package that’s clearly been maintained with distance cruising in mind.
