Extended Fleet · By Arrangement
When the day needs a different boat.
Same captains, more horsepower. Same standard, more range. For Dry Tortugas runs, overnights, sailing days, and groups bigger than our Jeanneau will hold — we’ve got friends with the right boat.
The boats below aren’t ours. They belong to trusted partners — captains and owners we’ve worked alongside for years on Stock Island and around the Keys. Each boat is partner-owned and partner-operated, with the partner’s own captain running the day.
We bring these into the Six Fins family for the trips our Jeanneau can’t do: overnights, Dry Tortugas runs, sailing days, and groups of 8–12 guests.
Why book your partner excursion through Six Fins? Booking through Six Fins combines the resources of our experienced hospitality team with those of our excursion partner to help assure you and your party have the best ocean experience possible. We help match the vessel and experience to your group, coordinate the details, and remain involved in making the experience come together. You may also request a preferred captain. Many captains who work with Six Fins also work with our excursion partners, and we will coordinate your request whenever possible, subject to availability and the partner’s final staffing decision.
When to ask about a partner boat
Four reasons to upsize.
Our Jeanneau handles 90% of charter days beautifully. These are the days it doesn’t.
Dry Tortugas & Marquesas
70 miles offshore. Need a fast offshore hull and the range to make it a comfortable day-trip, not an endurance event.
Overnights aboard
Sleep on the boat. Wake up at a remote anchorage. Our Jeanneau is a day-boat; these are weekenders built for it.
Sailing days
If you want wind in the rigging instead of outboards on the transom, we have catamarans and sailing yachts in the network.
Groups of 8–12
Bachelorettes, family reunions, corporate days. When the Jeanneau’s 6-guest cap doesn’t fit, these do.
The Extended Fleet
Five boats. Five jobs.
Each of these does something our Jeanneau can’t. Click through for specs, captain, and inquiry.
2026 Freeman 37
The Dry Tortugas day-trip machine. Fast, dry, and built for running out and coming back the same day without beating anyone up.
SeaJazz 42 Catamaran
Wind power, stable deck, plenty of shade. The smart pick for guests who want a sailing experience without giving up the catamaran’s living space.
2017 Saba 50
Real berths, real galley, real range. Use her as a day-charter for big groups, or take her overnight to a Lower Keys anchorage.
Axopar 37
Scandinavian build, walk-around helm, real cabin below. The pick for guests who want shelter, range, and a bit of speed in one package.
Bali 4.1
Open-cockpit modern catamaran. Bali’s signature drop-down forward door turns the bow into a beach. Good for open-air entertaining.
Add-ons · Aboard any yacht
Of course there’s plenty of room for all your favorite toys.
eFoils. Underwater scooters. A 108-square-foot floating lily pad. Paddleboards. A WaveRunner tagalong. You name it — we’ve quoted it, towed it, and rigged it on board. Tap any for the full briefing.
eFOIL
Electric hydrofoil. The cool toy of the year.
Waydoo Subnado
Underwater scooter. Reef tours without the kick.
Lily Pad 18′ × 6′
Floating swim platform. Group naps, basically.
Stand-Up Paddleboard
O’Brien SUP. Glassy mornings, sandbar laps.
Yamaha WaveRunner VX Series
Jet ski tagalong. Yes, we’ll tow it.
Ask about availability when you inquire — most are on board most days.
