Summerland Key sits squarely in the stretch of the Lower Keys where the nearest full-service marine shop is a haul and a wait away. We close that distance by bringing the shop to you — a fully equipped truck, a certified technician, and no trailer required.
A mixed fleet, one mobile shop
Summerland's docks run everything from center consoles to small cruisers to the odd flats skiff staged for a backcountry run. Whatever's tied up at your seawall, the same principle applies: proper diagnostics before parts get replaced, ABYC-standard work on anything electrical, and Mercury factory diagnostics for Mercury outboards.
