Catamaran Tour Key West

A catamaran is the most common kind of boat on Key West tours, and I compared three that are sold as catamaran trips: a shark and wildlife viewing tour, a dolphin sail and a snorkel with a seafood boil. They cost $50 to $99, and all list free cancellation up to 24 hours ahead. Prices are in US dollars, checked in October 2026, and the booking links are affiliate links, as I explain on my about page. For the rest of the water, see my overview of boat tours in Key West.

My pick is the shark and wildlife catamaran tour: $99, 2 hours, rated 4.8 from 276 reviews.

Catamaran Key West Tours

A catamaran in Key West has two hulls, which makes it stable and shallow, and that matters around Key West, where much of the water near the island is shallow. It also means wide decks with room to move. Most of the best-known trips in my data use one, including the Fury reef trip on a 65-foot catamaran and the Fury eco cruise on a 45-foot power catamaran, which I cover on my snorkeling tour page.

The three Key West catamaran tours below are the ones sold under the catamaran label. Each offers a different reason to board: sharks, dolphins or food. For the Key West National Wildlife Refuge and the backcountry waters they visit, the Florida Keys tourism board is the official visitor source, and the marine sanctuary office covers the protected waters.

Sharks and Wildlife on a Key West Catamaran

The shark tour is run by Key West Extreme Adventures on the Tiger Cat, a 34-foot catamaran with shade. It is $99 for 2 hours, rated 4.8 from 276 reviews. The listing says the captains, all with over 30 years of experience in the Florida Keys, deploy a specially formulated scent to draw sharks close to the boat so you can watch them safely. You may also see sea turtles, stingrays, birds and dolphins in the backcountry waters.

Of the catamaran tours in Key West, this is the one with the most evidence behind it. Reviewers say the captain and his brother were wonderful and informative and that everyone got to see the sharks and take photos. It includes shaded seating, the captains and drinks, but not food, hotel pickup or tips. The meeting point is pier B behind the Opal Key Resort. It is a wildlife encounter, so I would not choose it for a quiet romantic evening, and I would tell small children what to expect.

Sail Key West by Catamaran

If you want to sail in Key West without paying for a schooner, the Sebago afternoon catamaran sail is the budget route. It is $50 for 2.5 hours, rated 4.4 from 149 reviews. The catamaran carries a round trip with unlimited beer, wine, sangria, soft drinks and water, and two marine heads. The crew heads for prime dolphin areas, and reviewers describe following a pod for a long time.

A sailing catamaran in Key West like this one is the easiest to book on short notice. It meets at the Sebago office on Lazy Way Lane, the small side street along the water between the end of William Street and Elizabeth Street. There is no snorkeling and no meal, which is why it is the cheapest. I would book it for a relaxed afternoon when the goal is to be outside with a drink. For the full set of dolphin trips, my dolphin watching page compares them.

Catamaran Snorkel with a Seafood Boil

The most generous catamaran tour is the other Sebago trip: $70 for 4 hours, rated 4.7 from 21 reviews. You get an all-you-can-eat seafood boil, a premium open bar, premium snorkel gear and guides for all levels, with snorkeling at two prime locations such as Sand Key or another reef nearby, according to the listing. The catamaran has spacious decks, plenty of seating and shaded areas.

Treat the rating as early. Only 21 reviewers have rated it, and one says the boil is not the best seafood they have had, although they enjoyed the crew and plan to book again. Another says they will book directly with the company next time, which is the sort of detail I would read before I booked. It meets on the Harborwalk at the Historic Key West Seaport, down Lazy Way Lane, at the next-to-last shop on the right.

The three differ most in how they treat the guests. The shark tour is a small-boat, one-purpose outing, the dolphin sail is a social ride and the boil is a party with a snorkel in the middle. None of them is a sunset trip by name, although the afternoon sail can run into the evening depending on your slot, so confirm the return time on the booking page. The Tiger Cat is a 34-foot boat, much smaller than the 65-foot Fury catamaran on my snorkeling page, and boat size is a reason to ask about capacity before you book.

Boat Key West: How to Choose Between Them

Pick the Key West catamaran by the day you want. A short wildlife outing suits the shark tour, a lazy afternoon suits the dolphin sail and a long social day suits the boil. The per-hour price is close: about $50 an hour for the shark tour, $20 an hour for the dolphin sail and $17.50 an hour for the boil. That is a simple calculation from the listed price and duration, not a measure of quality.

Check what is not included. The shark tour has no food and no hotel pickup, and the Sebago listings do not mention pickup at all. None lists a fixed departure time in the text I have, so the booking page is where you choose a slot. If sunset matters, my sunset cruise page covers the evening trips, and for paddling instead of a motor, see the kayak tour page.

What to Bring on a Key West Catamaran

A Key West catamaran has little shelter from the sun on the open deck, even with shade. Bring sunscreen, a hat, sunglasses and a light layer, because the wind on a catamaran deck feels stronger than on land. If you are snorkeling, add a towel; towels are not part of the Fury trips, and I would assume the same for others unless the listing says otherwise. Bring cash or a card for gratuity, which is customary and not included, and eat a proper breakfast if you are booking the shark tour, since it serves drinks only.

For anyone prone to seasickness, a catamaran in Key West is steadier than a monohull, but it is not immune to chop. If the forecast looks rough, use the free cancellation window up to 24 hours before the start.

Which Catamaran Tour I’d Book

When I pick a Key West catamaran, I’d book the $99 shark tour for something memorable, the $50 Sebago sail for an easy afternoon and the $70 seafood boil for a group, once more reviews are in.
