Good to know

What is the difference between transient and seasonal slips?

Transient slips are rented on a short-term basis, usually by the night or week, for boaters traveling through an area. Seasonal slips are leased for several months or a full year, giving local boaters a dedicated home port. Availability for transient docking often depends on peak holiday demand and advance reservations.

What services are typically included in dockage fees?

Basic slip rentals usually include water access and secure tie-ups, while electricity may be billed separately or metered based on consumption. Full-service marinas often include Wi-Fi, pump-out access, and shower facilities, whereas basic boat docks may only provide a place to tie off.

How much does it cost to keep a boat at a marina?

Pricing is typically calculated per foot of the vessel, measured by length overall. Transient rates often range from $2 to $5 per foot per night, while seasonal leases can cost anywhere from several hundred to several thousand dollars depending on the region and included amenities.
