In a protected cove in Spanish Water Bay, just outside Seru Boca Estate's northern boundary, is Seru Boca Marina. Seru Boca Marina offers floating slips for 128 vessels up to 150 feet in length. There are two piers at the end of the two main docks that can accommodate vessels of varying lengths. The main dock has its own finger pier for easy access onto a vessel docked in the slip. The slips have power and water availability. Seru Boca Marina provides its slipholders with 24-hour security. The dockage fee is based on the size of the vessel. A Dockmaster or staff member are on duty each day and may be called on VHF radio.
