Blackline Marine Rentals
Shell Key Preserve is a natural-shoreline destination that can inspire swimming, sightseeing, and a slower day on the water. A Shell Key boat rental plan begins with current marine conditions, the active Boatsetter reservation, and the operating boundaries for your rental.
Why it works
The undeveloped coastal setting offers a different view from the area’s busier waterfronts.
Shell Key can suit groups interested in unhurried sightseeing, swimming, and time together outside.
Surrounding waters and shoreline may offer opportunities to observe birds and marine life respectfully.
The boat
Every Blackline rental features our 2025 Bentley 243 Swingback Tritoon, picked up at Mariner’s Cove Marina in Gulfport.
Explore the boatPlan your day
Treat Shell Key as a route idea rather than a guaranteed destination. Conditions and rental boundaries determine whether a visit is appropriate.
Thunderstorms, lightning, wind, visibility, and water conditions can change the plan.
Follow posted guidance, local regulations, and any instructions that apply to protected shoreline and wildlife.
The active Boatsetter listing and confirmed rental agreement control where and how the boat may be operated.
