Fuel Dock

As the only authorized ValvTect marina on the New Hampshire seacoast, we offer both diesel and gasoline ValvTect marine fuel. Marine diesel helps prevent bacteria, slime and filter plugging, extends fuel filter life, lubricates fuel injectors and reduces smoke. For gasoline engines, ValvTect helps prevent ethanol-related problems, increases power, reduces fuel consumption and stabilizes gasoline for up to one year.


The Fuel Dock opens 15 minutes after the office and closes 1/2 hour before the office closes.


  • For a single fuel purchase of 500 gallons or more, a discount of 10 cents per gallon applies.
  • Commercial Fishing Vessel Discount available. Details at fuel dock.

Hail the fuel dock on VHF channel 71.

Our favorite marina to visit while cruising northern New England. Wonderful facilities, well trained staff, restaurants a short walk plus loaner cars for trips to Portsmouth. Visit every summer. Reasonable fuel prices.

We had planned to stay in downtown Portsmouth but chose Wentworth instead. We made the right decision. A superb facility. Great staff and very nice loaner car.  A very nice pool setup with bar service. We launched our kayaks and had fun exploring the area. Important for us is good WiFi which they had. Worth the money.
