About

Meet SeaQuinn — Exceptionally clean 3 cabin Owner’s Version | ICW-Capable | US Documented and Duty Paid

SeaQuinn represents an opportunity to acquire a thoughtfully upgraded, meticulously maintained cruising catamaran owned by an experienced captain.

Having cruised extensively between New York, Florida, the Abacos, and the Exumas, SeaQuinn has proven herself as a reliable and comfortable passagemaker equally suited to seasonal migration, extended Bahamas cruising, or liveaboard exploration.

We take pride in our happy customers

I chose Zee (Zvonimir Kalinic) after posting an ad for a broker on Yacht Sales from about 15 other brokers because he showed professionalism and care right away compared to the others. Most of the brokers never intended to show people my boat but yet somehow expected to collect commission. Zee met me in Novigrad and spent 3 hours taking photos and drone footage and throughout the listing period was communicating continuously and advising me about any offers that came through. His service was at a high standard that I was extremely happy with and felt comfortable at all times especially since I’m in Sydney and my boat is in Montenegro. I can’t recommend Zee highly enough to anyone looking to sell their boat with peace of mind.

— Mark Eymes

The brokerage team has been amazing. They helped me find the right catamaran for our family of four, with enough space for extended family and friends to stay with us anytime. The broker really helped me narrow down what I needed. I started with a long list and eventually narrowed it down to something that was the right fit and price for me.

— Adam Munder

Our broker Mike Rybas was excellent – great experience!

— Chris Hannant

I cannot speak too highly of Andrew Hodgdon and his colleagues at the Multihull Company.

The process of selling my boat was very smooth and well managed and with excellent communication – especially important as I was unable to be nearby during the sale process. Andrew’s deep knowledge of the market and my boat was very reassuring. We spoke regularly and he kept me closely advised all the way through to a happy sale. I found him a good guy, very helpful, willing to share and bounce ideas around, and I enjoyed working with him. Highly recommended!

— Allan Morrison

Andrew Hodgdon and The Multihull Company are really professional! I just closed a deal with them, and everything was pretty smooth. Andrew was punctual, showed a lot of expertise, and he was honest about all the problems with the boat. He is also giving me the support I need to run all the projects on this boat. This whole process was much better than I was expecting, and I recommend this team! Thank you, Andrew.
