Marinas price slips by the foot, so the honest answer to "how much does it cost to keep a boat at a marina" is a formula: your boat's length overall times the local per-foot rate, plus electricity and extras. In the US that per-foot rate commonly runs from around $10 to $50 per foot per month, with premium big-city and resort harbors well beyond $100. Here is how the pricing works, what is and is not included, and where the real savings hide.
- Slips are billed per foot of length overall (LOA), per month or per year; your 32-footer pays for 32 feet.
- Typical US wet slips run about $10-50 per foot per month; hot markets (Miami, the Northeast in season, resort harbors) go far higher.
- Transient (nightly) dockage commonly runs $2-7 per foot per night.
- Electricity, liveaboard fees, and winter storage are usually extra; water and parking are usually included.
- Annual contracts, mooring fields, and dry stack are the three big levers for cutting the bill.
#How marinas price slips
Nearly every marina bills by LOA: length overall, including pulpits and swim platforms, not the number on your registration. Rates are quoted per foot per month (or per year, often with a discount), and slip size classes matter: a 36-foot boat in a 40-foot slip usually pays for the slip. Location inside the marina moves the price too, with T-heads and easy-access slips at a premium. The billing behind this, per-foot rates, metered electric, seasonal contracts, is exactly what marina management software administers, which is how we know the pricing patterns.
#What the ranges look like in 2026
- Inland lakes and quiet coastal areas: roughly $8-20 per foot per month.
- Typical coastal cruising areas: roughly $15-35 per foot per month.
- Major metro and high-demand coasts (South Florida, the Chesapeake in season, California): roughly $30-60 and climbing.
- Trophy harbors and resort marinas: $100+ per foot per month is real.
- Transient dockage: commonly $2-7 per foot per night, higher at destination docks in season.
So a 30-foot boat might cost around $450 a month at a mid-range coastal marina, $250 on a quiet lake, and four figures in a marquee harbor. These are planning ranges, not quotes: rates vary block by block, so call two or three nearby marinas, ask for the per-foot rate and the fee schedule, and compare like for like.
#What is included, and what is extra
Usually included: the slip, fresh water at the dock, parking, restrooms and showers, and basic security. Usually extra: electricity (metered per kWh or a flat monthly amp-based fee), liveaboard fees if you live aboard, pump-out at some facilities, winter haul-out and storage in cold climates, and dinghy or trailer storage. Two questions that separate marinas: whether electric is metered fairly, and whether the contract auto-renews with rate escalations. Proof of insurance is almost universally required.
#How to pay less for the same water
- 1Commit annual instead of monthly: discounts of one to two months' equivalent are common.
- 2Take a mooring ball instead of a slip: mooring fields often run a third to half the cost, at the price of dinghying ashore.
- 3Consider dry stack for trailerable powerboats: launch-on-demand service that often beats wet slip pricing.
- 4Go one harbor over: rates drop fast outside marquee zip codes, and the boat does not care about the address.
- 5Book transient stops ahead in season: marinas with online transient reservations post real availability and rates, no phone tag.
A $2 lower per-foot rate can vanish behind flat electric fees, mandatory service charges, or a stingy definition of LOA. Ask each marina for the full fee schedule and compute your boat's true monthly number before choosing.
Marine OS is marina management software: it runs the per-foot billing, metered electricity, and transient reservations described above for marina operators.
