Location & Overview Queen's Harbour Marina is a distinctive, gated marina in Jacksonville, Florida, just off the Intracoastal Waterway, built around a private, spring-fed lagoon accessed through a 110-foot lock. This lock-and-lagoon design shields boats from tides, current, and wake once inside, giving owners a controlled, non-tidal basin to keep their vessels rather than an open, tidal marina setting. From the lagoon, boaters have quick access to the ICW and are just a short run from the St. Johns River, the Atlantic Ocean, and the Mayport Inlet Sea Buoy about 8 miles away.

Lock, Lagoon & Slips The marina's 65 fixed concrete dock slips sit in water 8 feet deep or more, accommodating vessels up to 100 feet with metered 30 and 50 amp electrical service. Fishermen heading offshore before sunrise, or boaters returning after the lock closes for the night, can use the 120-foot floating dock just outside the lock, complete with its own fish cleaning station, shore power, and water. An on-site harbormaster and staff help boaters navigate the lock, and provide weather updates, ice, and general boating assistance along the way. Transiting a lock adds a layer of precision to every trip in and out, and the occasional bump or scrape against a lock wall happens even to experienced boaters — DS Diving's underwater damage evaluations give owners a clear, filmed look at any resulting hull or running gear damage before deciding on next steps.

A Private Residential Marina & Lagoon Community Queen's Harbour is part of a private yacht and country club community, with gated access limited to residents and guests, backed by 24-hour video surveillance and roving vehicular and foot patrols. Beyond the main marina, many homeowners along the lagoon maintain their own private docks right at their backdoor, built to community standards meant to preserve the lagoon's appearance and value. DS Diving supports both the marina and individual homeowners with piling inspections, cleaning, and preventative pile wrapping, helping protect the lagoon's dock infrastructure from barnacles, algae, and wood-boring marine organisms over time.

Boat Care in a Controlled Environment The lagoon's controlled, non-tidal water level is a genuine advantage for long-term storage, but a calmer environment doesn't mean a boat's hull stays clean on its own. DS Diving's underwater hull cleaning removes marine growth from the hull, running gear, and through-hull points, keeping vessels docked at Queen's Harbour efficient and ready to run, whether they're tied up in the main marina or at a private backyard dock along the lagoon.

Nearby Destinations Queen's Harbour puts boaters within reach of some of Northeast Florida's best-known destinations, including St. Augustine and Fernandina Beach, both about 30 miles away, and the Jacksonville stadium and Metro Park area roughly 25 miles distant. With the Mayport Inlet Sea Buoy just 8 miles out, offshore access is close at hand for boaters heading out to fish or cruise the Atlantic.
