From the dockmaster's desk
If you called five marinas about marina fuel docks, you'd get five different answers — not because anyone is hiding the truth, but because every harbor runs on its own contracts, depths, and storm policies. This page is the version we wish every dockmaster had time to give a first-time caller.
The fuel dock is often the busiest piece of infrastructure at a marina. Pump speed, fuel type, hours, and dockmaster competence directly affect whether you spend 15 minutes or two hours fueling on a Saturday morning.
Most U.S. marinas offer regular gasoline (87 octane, often ethanol-free) and ULSD diesel. Fast pumps deliver 25–45 gpm for diesel and 8–15 gpm for gasoline. A trawler taking 400 gallons of diesel is 10 minutes at a fast pump and 30+ minutes at a slow one.
Marina fuel is typically $0.30–$1.00/gal above the nearest road station because of bulk delivery costs, dock infrastructure, and lower volume. The cheapest fuel in any region is usually at a municipal or fuel-only fuel dock, not a resort marina.
Many marinas now offer fuel discounts for slip holders (5–25¢/gal), tournament rates, and pre-buy programs. If you take 1,000+ gallons a season, ask. Most dockmasters quietly extend captain-discount programs not listed publicly.
