MarineMax Marathon

MarineMax Marathon Marina is the Florida Keys' premier full-service boating facility located at 77 Coco Plum Drive in Marathon, originally established in 1994 as Shelter Bay Marine and now operated as part of the MarineMax national marina network — the largest recreational boat and yacht dealer in the United States. The marina's protected location on a non-flow-through canal, shielded from wind on three sides, provides an ideal and secure environment for both wet slip dockage and high-and-dry outdoor rack storage for boats of varying sizes, with indoor storage options also available for seasonal boaters. MarineMax Marathon offers a comprehensive suite of professional onsite marine services including mechanical systems repair, electrical systems, fiberglass and composites repair, boat paintwork and finishing, carpentry and joinery, hydraulic systems, engine repair, and full repowering, supported by a knowledgeable service team dedicated to keeping vessels running at peak performance year-round. The marina's on-site fuel dock, ship store stocking Mercury and Yamaha parts, and new and brokerage boat inventory — including Boston Whaler, Sea Ray, Aquila, Cruisers Yachts, and Aviara — make MarineMax Marathon a one-stop destination for Florida Keys boat owners and visiting boaters alike.
