Marina & Dockage Cost Calculator

Dockage is one of the largest recurring costs of keeping a yacht — and it varies wildly by port. Pick a real marina location and this tool estimates your monthly, seasonal and annual slip cost from current per-foot rates, then tells you whether a daily transient slip or a monthly contract is cheaper for your usage. It accounts for beam, electricity, water, pump-out, liveaboard surcharges and summer premiums.

Methodology & sources

How dockage costs are calculated

Monthly slip cost is length × per-foot rate (or length × slip width × area rate when "charge by area" is on). Slip width defaults to beam plus clearance; wide-beam vessels over ~30% of LOA add a surcharge. Utilities, a liveaboard surcharge and a summer premium are added on top. Transient daily rate is derived from the monthly rate at a factor consistent with published marina rate sheets, and the break-even is the number of nights per month at which a monthly contract becomes cheaper than paying daily.

Marina & Dockage FAQ

How much does it cost to dock a boat?
Long-term monthly rates run about $10–$35 per foot at inland and mid-tier coastal marinas and $50–$100+ per foot at premium waterfront ports. Transient daily rates are roughly $2–$8 per foot per day. A 50ft boat might pay $1,500–$2,500 a month at a mid-tier marina — far more at a premium port like Monaco.
Is it cheaper to dock daily or monthly?
Monthly is far cheaper per night. Break-even is usually around 6–7 nights per month — dock more than about a week each month and a monthly slip wins. The calculator computes your exact break-even by port and length.
Why is Mediterranean dockage so expensive?
Premium Med ports like Monaco, Antibes and Palma combine very limited berths with peak summer demand from large yachts. Monaco can exceed $300 per foot per month in season — many times a US marina — and summer premiums push it higher.
What extra fees come with a slip?
Beyond the per-foot rate: electricity and water (flat or metered), pump-out, a liveaboard surcharge (often 10–20%), and sometimes a seasonal premium. Wide-beam vessels like catamarans may pay extra or be charged by slip area.
How is a marina slip fee calculated?
Usually by length overall at a per-foot rate × the period (day, month or season). Some marinas charge by slip area (length × width), which penalizes wide beams. Utilities, liveaboard surcharges and seasonal premiums are added on top.
