Ao Po, TH


‘ASMARA ALIDA’, formerly ‘AOSANGO’, was built under the close supervision of her first owner and holds CE certification of conformity.  Now in her second ownership, the boat has benefitted from two successive dedicated owners, she has within the last year had a complete re vamp of her electrical set up… all new lithium-ion batteries with excellent battery management, a new 1500 watt solar array with new MPPT control units. The FISCHER PANDA PMS11-13 Kw generator gives additional self-sufficiency to the boat. She has an excellent fuel capacity and an intelligent tank system. There are many other aspects aboard that the present owner has upgraded to ensure hassle free cruising.

The extra comfortable living aboard is afforded by full air conditioning, generous bathrooms with electric heads, a large modern galley and large sheltered cockpit.  Add to this the fine sailing characteristics and fine construction methods ‘ASMARA ALIDA’ will have wide appeal.

A four double cabin boat, with additional sleeping capacity in each forward deck locker/cabin, ‘ASMARA ALIDA’ is a spacious home afloat and perfectly self-sufficient.

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

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.
