Seller says millions of dollars have been invested in this catamaran over the years. The vessel was custom designed and built for long range traveling and she's ready to travel the world if the buyer so desires. She could be a great opportunity for someone that wants to take her out and explore today, or could also be a great opportunity for someone that wants to remodel and use as more of a luxury yacht with the ability go where your heart desires!

I recently met with the seller... he said he had the vessel custom built and has done ground breaking ocean research for the past 20 years with her. He's now ready to move on to the next chapter of his life and he's realistic in considering all reasonable offers. He would like to see the vessel go to someone that will truly enjoy her and use her to her full potential. 

The Vessel that Made History in the North Pacific Subtropical Gyre
Serving as a platform for underfunded scientists and graduate students, the Alguita enables them to access areas of the ocean that are prohibitively expensive to study on other vessels.

Alguita's 25-foot beam gives her the work area and stability of a much longer mono-hull. Her A-Frame gantry, coupled with 600 meters of 8mm steel cable, can accommodate surface, mid water and bottom trawls, as well as benthic grabs and CTD rosettes. She is capable of deploying a wide array of marine-oriented scientific instruments. There is ample storage space for specialized research equipment, a small wet lab and a secure area for dive gear and tanks that can be filled on board. Each hull has reverse transom with steps for ease of access to the water or to inflatables. The interior is thermostatically heated and air conditioned. She can comfortably accommodate up to five researchers, together with Alguita?s two experienced crew, in individual bunks for long voyages. She has bunk spaces for 4 charter researchers whom can join for overnight or day cruises. A 500-gallon per day desalination unit supplies high-quality hot and cold water to the fully equipped galley, as well to the sinks and large shower.

SLIP AVAILABLE TO APPROVED BUYER. The seller owns the slip and is willing to rent the slip to an approved buyer.

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.
