Do you like Exquisite Wiring? Do you like Quiet Propulsion? Do you dislike Boat Yoga? Don't hang upside down in the bilge. The diesel auxiliary on this fantastic schooner rises to meet you in the pilothouse! Down in the former engine room, a pair of 90 hp equivalent electric saildrives provide quiet efficient de-coupled propulsion. For more than two hours you can run at cruising speeds on stored electricity alone - utilizing the 50 Kwh lithium propulsion bank. Hybrid auxiliary energy generation provides up to 800 nautical miles of additional motoring range. Extensive solar charges household and hotel loads and shorepower charging systems provide economical and fast range generation. And, the single-handable and adaptable schooner rig harnesses the wind providing for fast comfortable passages with 200 mile averages easily attained. This is an Eco-cruiser in every sense.

Do you like Warmth & Comfort? Do you like Safety & Security? Are you looking for a Home on the Sea that can take you anywhere in the world? Singawing was custom designed for world cruising. She was custom built and built tough to encapsulate her crew in safety and comfort. Her hull, deck, and house layups are intentionally over-engineered to take what the sea might bring. Thick foam coring, extensive hull & house Aerogel insulation, insulated & tinted windows, heating and air conditioning, excellent ventilation and pilothouse design make her comfortable below at any latitude. Skippers will take comfort behind her heated interior and exterior heated helms as well as in her intelligently designed, accessible, and maintainable systems, running rigging led via conduit to the helm's electric winch, easily furled sails, renewed standing rigging, welded stainless safety railing,and oversized ground tackle. Crew will enjoy glowing staterooms, expansive decks, a secure central cockpit, the warmth of hydronic heaters (& towel warmers), warm interior woodworking and paneling, and the output of a very sensible working galley.

Do you like Adventure? Do you like easy-to-maintain reliable systems? Do you dislike Extensive Refit? Buy a boat that is completely and thoughtfully set-up! I have known Singawing and her Seller for three decades. He grew up on a sailboat and has become one of the top minds in electric propulsion. He chose this hull wisely and transformed Singawing from a world cruiser into an Eco-Cruising Global Adventure Vessel with few equals. Singawing was extensively refit 2014-2016 - not just to refresh her - but to advance her. In addition to a state-of-the-art hybrid propulsion system, she received new lithium batteries (both propulsion & house), complete re-wiring, additional solar capacity, a tough 2-part Awlgrip paint job, new decks, new hatches, new deck hardware, welded safety railings, complete re-plumbing, new tanks, standing rigging , new buried running rigging, new furling systems for main and headsails, an electric helm winch, over-sized ground tackle, RADAR, 12" touch screen chartplotter, digital wind instruments, VHF radios, GPS, dual depth-sounders, autopilot, cell & wifi boosters, gas-filled double-pane windows, LED lighting, cedar-lined closets, tongue & groove cabin overheads, new cushions, copious refrigeration, an ice-maker, and washer & dryer. Singawing is also replete with toys & tenders for exploring our watery world. She includes a nesting sailing/rowing dinghy, ttwo single kayaks, and a double kayak for exploring distant anchorages.

The next owner will benefit from the top quality thought, carefully selected components, extensive equipment, and painstaking execution that Singawing has received. She is a smart boat. She is a wise choice. She can be yours at a very fair price. Contact Matthew to schedule a viewing and get started on your next adventure!

Your team delivered on every mark. You’ve got an amazing broker in Mark Wattrus and I’m confident you will have continued success moving forward together. He was available 24/7 whenever I had questions. We had a great initial visit on the boat and his marketing plan and photos were superb

— Jimmy

I bought a yacht that I had never seen. I did this because I trusted my broker Andrew Holland. It was not an easy job for Andrew, as I am an experienced boat builder and owner of previous yachts, but work in West Africa. Imagine how hard it was to communicate what I was looking for. Andrew came up with exactly what I wanted. He dealt with time delays, all my questions at odd hours, and was there for the survey. He reported honestly and professionally. After buying the yacht, I arrived at the boat on a Sunday night, after dark, after travelling from West Africa to the Caribbean, and found it was better than expected. He never pulled punches and made me aware of shortfalls. I expected to spend my one month leave working on the boat, but actually spent less than one week, and was able to spend 3 weeks sailing – wonderful bonus.

Thank you Andrew for putting up with all my questions, all my worries and all my crazy out of the time zone concerns – you were totally professional, but also I know that if and when we meet up, it will be like a friend finally meeting. You are always welcome on Aseka.


— Beverly Cory

Outstanding company with professional subject matter experts. If I were to buy or sell cruising sailboat, particularly a catamaran, Andrew would be my go to broker.

— JT

I have been sailing since I was a child and attended Massachusetts Maritime Academy. But when my wife and I began the process of purchasing an ocean cruising/racing catamaran, I realized that this is a world unto itself. Obviously, we needed to find someone knowledgeable to help us make an informed decision. More importantly, we needed someone honest and willing to put our interests before his or her own. I was lucky to work with Phil Berman at The Multihull Company. He repeatedly shunned the fast buck, choosing instead to work the long road to connect us with the “perfect boat”. I would be glad to recommend Phil and his company to anyone planning to purchase or sell a performance sailing machine.

— Eric Boutiette

Andrew Hodgdon was our broker when we bought our 2018 Lagoon 450F in Antigua in April 2922. He provided great service and was very attentive to our needs. We would highly recommend Andrew and the Multihull Company.
