Premium production
Australian family-owned builder of long-range flybridge and sedan motor yachts — the M-Series (M50 to M75), S-Series (S50 to S75) and Offshore M600/S600 — built at Coomera on the Gold Coast, founded in 2003 by Bill Barry-Cotter.
Maritimo is designed and built by hand in Australia, and makes long-range motor yachts. Its founder, Bill Barry-Cotter, has spent more than sixty years seeing that each one does what the yard promises of it -- experience becoming knowledge, and knowledge what lets a builder develop, improve and solve. The company came up through competition and still races, and it counts its owners and the people who build the boats as the same foundation.
