About Us- New England's Premier Resort

Wentworth by the Sea Marina, the ultimate in comfort and service, is nestled in the heart of the New Hampshire Seacoast. We are only minutes from open ocean sailing.

Our professional staff will greet you and cater to all of your needs, from fueling your boat to making your dinner reservations.

We have numerous slips that can accommodate vessels up to 200 feet. Relax in our heated pool, play tennis or golf, then dine at one of historic Portsmouth's fine restaurants. Please enjoy breakfast, lunch or dinner at The Green Bean's fantastic sea side location (603) 559-1006. Passing time comes easily at Wentworth by the Sea Marina.
