Zvonimir heard that my vessel was back on the market and reached out to see what was going on. Nothing wrong with the boat! He put me in touch with Charles and we got her sold. Thanks for all the support and making it happen TMC!
Chuck was amazing throughout the entire process. Not sure how we could have navigated this without him and the Multihull team!
It gets no better than The Multihull Company. I’ve watched their great videos for years. When it was time to sell my catamaran, there were no other brokerages in consideration. THEY ARE THE CATAMARAN MARKET LEADERS!! Captain Will Miller has taken the company to the top level. They had an interested buyer prior to my listing going live. I was under contract the first week. The Multihull Company is an impressive organization.
Was a pleasure working with Andrew Hodgdon as buyers agent for our recent multihull purchase. Very knowledgeable of this space and for sure my first call buying or selling a yacht.
