About Marinas

What is the cost of docking at a Marina?

Dockage rates may be based on a daily, monthly, seasonal, or annual fee. They also vary based on the length of the boat or slip. Public Marinas often charge lower fees and their rates may be subsidized by public funding.

What is the difference between a Marina and a Port?

Marinas are facilities designed to serve small recreational boats and yachts. Ports are designed to accommodate large commercial vessels, including cargo ships and large passenger ships. A port is also likely to include a customs station and customs officials.

What documentation is required to lease or rent a slip?

Marinas typically require a written lease. In addition, boaters are usually required to provide proof of boat registration or a USCG certificate of documentation, a copy of a driver's license, and a copy of current boat insurance. Long-term leases may require additional documentation.
