Renovated in 2018, the property blends modern finishes with the relaxed Florida Keys boating lifestyle. A true boater's dream, each side offers its own 30' concrete dock and seawall (60' total) complete with 30-amp shore power. Enjoy quick ocean access and easy Gulf access via Vaca Cut, making this an exceptional setup for anglers and boating enthusiasts alike. The waterside outdoor spaces are designed for entertaining and enjoying the Keys lifestyle, featuring string lighting, solar-lit dock pilings, under-dock fish lights that attract snapper and tarpon, and frequent manatee visits along the canal. Located directly adjacent to Oceanfront Park & Dog Park, owners and guests enjoy immediate access to one of Marathon's premier waterfront parks offering a dog park, kayak launch, open green space, waterfront walking areas, playgrounds, and frequent community events.
