Locally owned. Captained by Dean.
Marine13 is the One Stop Charter Shop for Treasure Island — a small, personal operation focused on getting you on the water quickly and safely.
Marine13 is run by Captain Dean out of Treasure Island, Florida. After years of running trips informally for friends and family, Dean built Marine13 to open the same experience up to visitors and locals — real Gulf charters with a captain who knows every pass, sandbar, and island in the area.
Every trip is small-group, hands-on, and shaped around what you want. Sunset for two, birthday party of six, a family shelling trip to Shell Key, or a private memorial service — we design the day and put you on the water.
Safety first
USCG-licensed captain, life jackets in every size, weather-first policy.
Local knowledge
We know the passes, the sandbars, the dolphin spots, and the best shelling tides.
Every trip is custom
Standard trips are just a starting point — tell us your day and we'll plan it.
Guest-first
Small groups only. You're not on a bus tour — you're on our boat.
Design your day on the water.
Whether it's a sunset for two or a private group day around Shell Key, we'll plan it with you and put you on the water with a captain who knows the coast.
