This is an offshore charter with open-water conditions and 60–75 minutes of travel time each way. The primary booking party must be 21+; children under 18 must be with a parent or legal guardian. Guests should be comfortable swimming for water activities and able to board and move safely on the vessel.
This booking is for the whole experience, which fits up to 6 guests.
Reservations made within 7 calendar days of departure are non-refundable. Cancel more than 7 calendar days before departure for a full refund. Full refund if Six Fins Charter cancels due to unsafe weather conditions or other circumstances initiated by the owner/operator.
Complete the required forms prior to arrival. For groups up to 6 passengers, complete the insurance waiver. For groups with a 7th or 8th passenger, the primary renter (age 21+) and the captain complete a Bareboat Agreement together at the dock.
Plan for about 60–75 minutes of travel time each way in open water.
This is an offshore charter. If you are prone to seasickness, take preventative medication.
Key West, Fl.
Six Fins delivers consistently excellent experiences across both their boat charters and jet ski tours, with guests raving about the personal attention from their captains and guides. Names like Captain Dustin, Brian, Chris, and Jack come up repeatedly for their knowledge, hospitality, and ability to make everyone feel comfortable regardless of experience level. The sandbar tours are particularly popular, taking guests to stunning, secluded spots that showcase the real beauty of the Keys beyond the typical tourist areas. What really sets this operation apart is how their guides go above and beyond when guests need extra help. First-timers struggling with jet skis get patient instruction and additional support rather than being sent back early. The boats themselves get high marks for cleanliness and amenities (the lily pad is apparently a crowd favorite), and families especially appreciate how welcoming the crews are with kids. From prep calls before your trip to thoughtful touches like rescheduling lunch reservations when weather shifts plans, the team clearly prioritizes making sure every detail of your day works out perfectly.
We booked a 6-hour snorkeling and sandbar trip. Captain Mike was fantastic, and Commodore Tiny was the bomb. Perfect weather, great locations and just a lot of fun all around. Would definitely recommend to any group or family who wants a fun day on the water on the keys.
