More range, more stability, and more usable space mean more days in Tampa Bay spent running where you want instead of planning around limitations.

Many experienced owners reach a point where their current boat feels tight offshore, underpowered for long runs, or too complicated to keep dialed in. The Sportsman Open 352 replaces those compromises with a layout and systems package designed to keep time on the water simple and predictable. A wide 11' 2" beam creates room to move without crowding the cockpit, while a 355-gallon fuel tank supports longer runs offshore or extended days running between St. Pete, Clearwater, and Sarasota without constant fuel planning.

Triple Mercury 400XL outboards provide up to 1,200 horsepower, giving the boat the power reserve needed to maintain cruise efficiency even when fully loaded with family, gear, and fuel. The 23° transom deadrise helps soften the ride in afternoon Gulf chop, increasing confidence when weather and water conditions change.

At the helm, the boat is built to reduce workload and keep navigation clear. Dual Garmin 22" displays, integrated through the SportLink system and paired with a Garmin radar, provide a wide and organized command center. Systems like Seakeeper Ride automatically adjust running attitude, helping the boat stay level and efficient without constant trim adjustments.

Fishing capability stays serious without turning the boat into a pure tournament platform. Twin 30-gallon pressurized aquarium livewells, dual macerated fish boxes, and an integrated sea chest keep bait and catch management efficient while preserving deck space for family and social use.

Inside the console, the lockable compartment includes a porcelain head, berth, sink, and shower, making longer island runs or full-day outings around Tampa Bay more comfortable without requiring a larger cabin boat.

This configuration is finished in Harbor Haze Blue hull sides, a white hull bottom, and triple white Mercury 400XL outboards, paired with premium Serenity Sileather Icecap White upholstery for durability in Florida sun and salt.
