How Much Does a Boat Slip Cost? Prices Explained
A boat slip costs by the foot, billed nightly, monthly or yearly. See real medians from marina rate sheets, what changes the price and extra fees to ask about.
A boat slip costs anywhere from about $200 a month for a small boat at a modest marina to well over $1,000 a month for a 40-footer in a busy boating area, and marinas price it by the foot of boat length. In Marinalo data from October 2026, the median nightly rate for a 40-foot boat is $120 in Florida (31 marinas) and $60 in Texas (2 marinas), while the median monthly rate is $976 in Florida (26 marinas) and $660 in Texas (5 marinas).
Those numbers come from published rate sheets, not estimates. Below you will find how marinas build a price, what separates a transient slip from a seasonal or annual lease, the extra fees that catch new boat owners out, and a short checklist of questions to ask before you sign.
How marinas price a boat slip
Most marinas charge a rate per foot of boat length, then multiply by the length of your boat or the length of the slip, depending on the marina's rule. A 30-foot boat in a 40-foot slip may be billed as a 40-footer. Always ask which length counts: the boat's length overall (including the swim platform, bow pulpit and anchor) or the slip size.
The same slip can be sold in three ways:
- Nightly (transient slip): a short stay, usually for visiting boaters. It is the most expensive way per day because the marina can only count on it filling a few nights at a time.
- Monthly: a rolling or fixed-month agreement. Many marinas offer a lower daily rate the longer you commit.
- Annual (or seasonal): a lease for a year or for a season. It is usually the cheapest per month, but you commit to the whole term.
A monthly transient rate and a long-term monthly lease are not the same product. Marinalo keeps them apart so one is never compared with the other (see the methodology page), and you should do the same when you compare quotes.
What a boat slip costs: real medians, October 2026
The table below shows median rates by boat length from the Marinalo slip price pages. Each figure is the middle value among marinas that publish an official rate for that length, and the last column shows how many marinas sit behind it. A dash means no marina has a published rate that we could read.
| Boat length | Florida, per night | Florida, per month | Texas, per night | Texas, per month | Texas, per year |
|---|---|---|---|---|---|
| 20 ft | $55 (29 marinas) | $410 (21) | $30 (2) | $210 (3) | $2,310 (3) |
| 30 ft | $86 (31) | $675 (24) | $45 (2) | $320 (5) | $3,520 (4) |
| 40 ft | $120 (31) | $976 (26) | $60 (2) | $660 (5) | $5,170 (6) |
| 50 ft | $150 (31) | $1,250 (25) | $75 (2) | $825 (3) | $9,075 (3) |
| 60 ft | $180 (31) | $1,410 (24) | $90 (2) | $990 (3) | $10,890 (3) |
Source: Marinalo data, October 2026. Florida: 304 marinas listed, 49 with a published rate. Texas: 338 marinas listed, 14 with a published rate. The Texas figures rest on very few marinas, so treat them as a first reading, not a market average. Florida has no published annual rate for boats up to 50 feet in our data, and only one at 60 feet.
Two things stand out. Prices climb steadily with length, and the gap between Florida and Texas is large, but the two states are measured on very different numbers of marinas, so do not read it as a like-for-like gap. Our two state studies go deeper: Florida boat slip prices in 2026 and Texas boat slip prices in 2026.
A rough per-foot view
Dividing the medians by boat length gives a quick feel for the rate per foot. This is simple arithmetic on the numbers above, not a rate any marina quotes.
- Florida nightly: about $2.75 per foot at 20 ft, about $3.00 per foot at 40 ft, and $3 per foot at 60 ft.
- Florida monthly: about $20.50 per foot at 20 ft and about $24.40 per foot at 40 ft.
- Texas annual: about $115 per foot at 20 ft and about $129 per foot at 40 ft.
Use these only to sanity-check a quote. If a marina asks far more or far less than the figures for your length, find out why before you commit.
What drives the price of a slip
- Location: Rates in the Florida Keys run well above the state median. In Marinalo data, the median nightly rate for a 40-foot boat is $240 in Islamorada (1 marina with a published rate), $186 in Key West (2) and $100 in St. Augustine (3), so a few miles can change the bill a lot.
- Boat length and beam: Wide boats and catamarans often cost more or are quoted separately, because they take more dock space.
- Dock type: Floating docks, covered slips, end-ties and slips on a protected basin cost more than open pilings or a seawall tie-up.
- Season: Many marinas have peak-season and off-season rates. Some publish several rates for the same boat, and Marinalo shows the lowest of them.
- Owner of the marina: City and county marinas often publish a fee schedule and may charge residents less than visitors. Private and resort marinas set their own prices.
- Contract length: Nightly is the dearest per day, annual leases the cheapest.
Extra fees to ask about
The base rate is rarely the whole bill. Ask a marina for a written list of everything that is billed on top of the slip, and compare quotes on the same basis. Common add-ons include:
- Electricity: some marinas include power, others meter it, and a boat with air conditioning can use a lot. Shore power is usually 30 amp or 50 amp, so check which your boat needs.
- Water, pump-out and trash: sometimes bundled, sometimes billed per use.
- Liveaboard fee: living on board often needs special permission and an extra monthly charge. See our list of Florida liveaboard marinas for places that allow it.
- Taxes: state or local sales tax may apply to slip rentals. Ask whether quoted rates include tax.
- Deposits, application and utility fees: a security deposit or a one-time set-up fee is common on leases.
- Insurance: many marinas require proof of liability insurance on your boat before you move in.
- Hurricane and storm rules: some marinas require you to move the boat or add extra lines before a named storm.
Marinalo only publishes a price when it can be found word for word in the marina's own rate sheet. Rates marked "call," "from" or "minimum," and rates reserved for special boats, are not published automatically, so a missing price often means the marina does not post one online.
How to compare a slip with other storage
A wet slip is the most convenient option, but it is not the only one. Dry stack, a trailer at home, or a boat lift can cost much less if you only boat a few weekends a month. Our guide to boat storage options compares them, and how much is my boat worth helps you put the yearly storage bill in proportion to the boat itself. To fold the slip into a full ownership budget, use the Marinalo boat cost calculator.
Questions to ask before you sign
- Is the price per foot of boat length or of slip length?
- Which length counts, and how is a boat with a swim platform measured?
- Is electricity, water and trash included? If not, how is it metered?
- What is the deposit, and when is it returned?
- What happens to the rate at renewal? Can it rise during the term?
- Are there rules about liveaboards, charters, boat work or rental of the slip when you are away?
- What are the hurricane or storm requirements?
FAQ
How much does a boat slip cost per month?
In Marinalo data from October 2026, the median monthly rate is $410 for a 20-foot boat and $976 for a 40-foot boat in Florida (21 and 26 marinas), and $210 and $660 in Texas (3 and 5 marinas). Individual marinas vary widely around those medians.
How much is a boat slip per foot?
Marinas bill by the foot, and the per-foot rate differs by location, contract length and season. From the medians above, Florida nightly rates work out to roughly $3 per foot and Florida monthly rates to roughly $20 to $25 per foot.
How much does it cost to dock a boat for one night?
For a 40-foot boat, the median nightly rate is $120 in Florida (31 marinas) and $60 in Texas (2 marinas). A short stay is called a transient slip and is the priciest way to rent a slip per day.
What is a transient slip?
A transient slip is a slip rented for a short visit, usually by night or by week, to boaters who do not have a lease. Transient rates are quoted separately from monthly and annual leases.
Do I need a slip to own a boat?
No. A trailer, a dry stack rack or a lift are other ways to store a boat. See boat storage options.
