The company
Small-island diving in Key West
Robert Trosset III started Finz in 2011 because Key West diving meant big boats and fixed schedules, and he wanted the small-boat, personal experience of diving on a small island. Rives Millwater, a captain with 25 years of diving out of the Outer Banks, is co-owner. The boats are six-packs, every trip carries a divemaster who gets in the water, and the team page names every captain and instructor.
Two boats: Finz Freeman and Park Shark, a 35-foot Razorhead with a Dometic gyro stabilizer, an air-conditioned cabin, a full head and a bow ramp for landing on Loggerhead Key in the Tortugas. Finz is a NOAA Blue Star operator and a Tripadvisor Travelers' Choice 2026 pick, ranked #18 of 397 in Key West.
“Our most comfortable vessel, with a gyro stabilizer.”
