St. Georges, GD


S/V Mirounga is a Grenada Islands based 1997 Prout 45 Catamaran for sale by owner. Mirounga is the ultimate liveaboard cruising machine. She is solid fiberglass under the waterline, cored above the waterline, with Kevlar reinforcement. The original Prout Catamarans are renowned for their safety, load-carrying capabilities, reliability, ease of handling and comfort, and were designed for long-term live-aboard cruising and ocean passages.

Mirounga was owned by her original owner until 2021. Shed been well taken care of and was ready to go the second owners (2021-2022) made a few improvements along the way to make her even better. They lived aboard very comfortably for a little over a year before returning back to land-life.

General Descriptions

Strength, essential in a catamaran design, is achieved by the one-piece hull and deck moldings bonded together with the bulkhead locations at strategic positions forming deep box sections, thus producing a monocoque shell system

  • The hull is molded using the latest molding techniques to minimize the risk of osmosis.
  • Gelcoat is of the isophthalic type. The first layers of glass are powder bound hand-laid with isophthalic resins using the Scott Bader System which is guaranteed for five years against osmosis. Incorporated in the lay-up are biaxial fibers.
  • High-stress areas are reinforced. The hull is of sandwich construction using end grain balsa above the waterline.
  • The deck molding uses top-quality Lloyds approved materials and incorporates end grain balsa sandwich to give strength where required and is also reinforced at high-stress areas and where through-deck fittings are sited.
  • Shroud plate areas are extensively reinforced. Incorporated in the deck lay-up are the latest biaxial materials for strength and weight saving.
  • Forward deck areas use trampoline nets.
  • All main bulkheads are substantially bonded to the hull and the deck with woven rovings. The bulkheads are located at strategic points to give compressional and torsional strength where required. Some are of composite construction, vacuum-bagged for effective weight saving.
  • Mast Support System – Mast loads are transmitted via an advanced HE30 aluminum space frame support system integrated with the rigging.
  • Interior – All interior furniture units are designed to complete a honeycomb type structure. All pieces are bonded into the hull and deck assembly in order to serve the dual purpose of function and strength.
  • Buoyancy – There are built-in buoyancy compartments both forward and aft in each hull and the water tanks form a double bottom system in the vessel ensuring buoyancy should she be holed.

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.
