50′ Alwoplast Overview
50′ Alwoplast Description
Catalyst is a well-maintained, Crowther designed custom power catamaran built by Alwoplast in 2004. She offers a 2-1/2 stateroom, 2 head layout (with the master stateroom on the pilothouse deck), Caterpillar 3126b main engines, water-maker, and a recent bottom job. Catalyst offers incredible flexibility in her range, beam, and draft. A lightweight hull with optimally designed hydrodynamics, she brings a 3,000 nm range at trawler speed or a 17 knot faster cruise. Seller reports a 6gph fuel burn at 8kts and 28gph fuel burn at 17kts. Another part of that unique design is her relatively narrow 20ft beam – allowing her to fit into many monohull slips, minimizing the need to find a double slip, compared to typical catamarans. Her shallow draft makes her ideal for the Bahamas, Keys or Great Loop cruising. Catalyst offer a vessel with an air draft less than 19.5ft making it possible to cruise the Great Loop. This bluewater or coastal cruising flexibility make her a great all-around cruising option.
Crowther power cat design experience + Alwoplast build quality is a proven combination for a smart, efficient, and dynamic power catamaran.

50′ Alwoplast Comments
With international acclaim in catamaran building from decades in production, starting in 1987, Alwoplast built superior custom catamarans, both power and sail. Their image depicts their commitment to engineering excellence and quality interior detail.
Catalyst has appeared in past issues of PassageMaker Magazine and MultiHulls Magazine and appeared in a trawler forum blog: “I think Alwoplast had a 50′ or so power cat at the Miami Show once…very impressive. I think Crowther also designed the Barbara Mae, a beefy 50-60′ or so power cat that struck me as one of the nicest designs yet. If I had the money to throw at a new Cat build, Alwoplast would be in the running.”

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.
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.
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.
Successful relationships cannot exist without it. At The Multihull Company we base every relationship on a firm commitment to earning and retaining our client’s trust.
Advice of any kind is valuable only when grounded in hard-won expertise. It too, must be trustworthy. Trust and expertise define the heart and soul of The Multihull Company. We are a team of skilled professionals who thrive on providing expert, trustworthy advice and service to catamaran and trimaran sailors around the globe.
