About This Home

Discover a rare opportunity to own an oversized boat slip with live-aboard approval in the desirable Cocoplum neighborhood of Marathon. Offering an impressive 22' width, 80' length, and 6' draft, this slip easily accommodates larger vessels, and a recently removed piling maximizes your available space. Nestled on the ocean side, you'll enjoy direct, fast, no-bridge access to the open water, perfect for avid boaters and anglers. Positioned at the end of the marina in a secure, gated section, the slip offers added privacy and quicker navigation straight to the ocean. A spacious Tiki hut extends your living area onto land, creating an inviting space for relaxing, entertaining, and embracing the island lifestyle. Stylish faux-wall panels on each side provide privacy while still capturing refreshing tropical breezes. It's a versatile, blank canvas ready for your personal touch. The marina features a community pavilion, bath house, and laundry facility, and this slip includes multiple storage units for all your gear and equipment. With a strong monthly rental potential and an unbeatable location, large slips with dedicated land-living amenities like this are truly hard to find. Don't miss the chance to experience this exceptional boat slip in paradise. Your ideal Keys retreat awaits!
