Cui Bono | 2015 Gunboat 60

Newport, RI, US


Cui Bono offers the ultimate multihull package, seamlessly combining luxury living with a high performance, easy-to-handle yacht.


New downwind sails, water maker, batteries and large hatches in 2023

Full 5-year rig service with standing rigging sent to Europe for inspection Fall 2023

6-month yard period with meticulous servicing of hydraulics, systems and rigging

She has proven herself an outstanding live aboard for extended periods whilst cruising throughout New England, Caribbean, The Bahamas and New Zealand. A minimum draft of 3.5 ft renders navigating and anchoring in shallow waters hassle-free.

Entertaining friends & family is effortless with Cui Bono's large aft deck lounge area, open floorplan dining space, and four spacious guest cabins. Those who have sailed her affectionately recall stories of brunch and cocktails at 20 knots!

The boat can be quickly switched into delivery or regatta mode where 260-mile days are easily achievable. In the absence of wind, the twin 55HP Yanmar engines will motor comfortably at 8.5 kts in flat water. Overnight deliveries have been done with just two people, but four is preferred with longer offshore passages. Another unique feature is the simplicity of shutting the boat down and only having one person look after and maintain her whilst dormant. When active, two crew are required.

Her constant upgrades and maintenance have not only enhanced performance, but more importantly ensured the yacht is completely safe and offshore-ready.

The boat is currently undergoing a maintenance period including its rig service and other items in Newport, RI. It may move to Savannah, GA for the remainder of the Winter season.

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.

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.
