A marina is a dock or basin with moorings and supplies for yachts and small boats and differs from a port in that it does not handle large passenger ships or freighters.
A marina may have refueling, washing and repair facilities, marine and boat chandlers, stores and restaurants. A marina may include ground facilities such as parking lots for vehicles and boat trailers. Slipways or boat ramps transfer a trailered boat into the water. A marina may have a boat hoist well operated by service personnel. A marina may provide in- or out-of-water boat storage.
Fee-based services such as parking, use of picnic areas, pubs, and clubhouses for showers are usually included in long-term rental agreements. Visiting yachtsmen usually have the option of buying each amenity from a fixed schedule of fees; arrangements can be as wide as a single use, such as a shower, or several weeks of temporary berthing. The right to use the facilities is frequently extended at overnight or period rates to visiting yachtsmen. Since marinas are often limited by available space, it may take years on a waiting list to get a permanent berth.
