Explore Marathon's Sandbars and Reefs Aboard a 20' Mako DC | Boat Tour | Fishing

Off the sun-scraped shore of Marathon, Florida, the 20' Mako DC carves across turquoise shallows with a Yamaha 150 humming under a compact bimini top. This family-friendly center-console is based at Grassy Key Marina (59073 Overseas Hwy, Marathon, FL 33050, USA), and it's configured for sandbar days, reef snorkeling, and light offshore fishing for up to seven people. The boat's 20-foot hull and dependable outboard make short runs to the nearshore reef fast and stable, while the open deck gives plenty of room to set up a cooler, masks, and fishing tackle. A typical outing here blends easy cruising with hands-on exploration of the Florida Keys reef tract — a living limestone and coral structure that supports schools of tropical fish, occasional rays, and beds of turtle grass that cradle juvenile fish. Skipping anchors at a favored sandbar turns the boat into a floating picnic table; dropping the anchor near the reef reveals channels of brain coral, fire coral, and pockets of spiny lobster habitat. On calm mornings you can watch the surface mirror the sky as frigatebirds and terns sweep overhead. Practicalities matter: the rental requires arriving 15 minutes early with valid ID, and operators enforce the US boating-safety certificate requirement for anyone born after January 1, 1988. That small administrative guardrail keeps outings safe without stripping the adventure — many groups use the Mako's nimble handling to hop between shallow snorkeling spots and deeper casts for mangrove snapper or permit. Why book this boat rather than a larger charter? The scale is part of its appeal. With room for seven, it's intimate enough for family conversation and flexible enough for a day of variable plans: reef swim, cast for dinner, or anchor at an offshore sandbar to relax. The Mako's simple layout encourages active participation — someone reels while another spots fish or sets a mask and fins for the next snorkel. Local context enriches the trip. The boat launches from Marathon, a Keys town that sits midway along the Overseas Highway and provides easy access to both nearshore patch reefs and the deeper channels that border the reef tract. Whether you're chasing a calm morning swim or a late-afternoon light show on the sandbar, the 20' Mako DC is a practical, memorable way to experience the Keys' marine landscape, fishing options, and leisurely sandbar culture. Expect changing seas and plan for sunscreen, shade, and reef-safe practices; coral and seagrass beds are fragile, so use mooring where available and avoid standing on reefs. Renters born after 1988 must carry a boating safety card. If you want guidance, local captains and shops in Marathon can offer tips on tides, best snorkeling holes, and the seasonal fish to chase too.
