Description

Large 4 bedroom home boasts one of the LARGEST PRIVATE BOAT SLIPS AT ANY RESIDENTIAL SF HOME IN MIDDLE KEYS at 24' WIDE x 50' LONG with plenty of room for up to 4 boats! New $120k dock was completed in 2017 with an upgraded concrete/reinforced coral boulder slip & additional 50' dock along the back of the property. Plus, the amazing location offers both ultimate hurricane protection -the owners 40' catamaran survived Irma tied in the slip without a scratch- & quick ocean/gulf access! At idle speed, you are only 15 min from the ocean & just 4 nautical miles away from a 65' clearance under the 7 mile bridge to cross into the gulf with access to 3 gas docks & 4 restaurants right around the corner. Yacht, sailboat, sport fisher, or catamaran-this property will accommodate all of boating needs!
