Portland Boat Works and Harbor One Marina’s well-maintained facilities are ideally and centrally located and easily accessible by car or boat.

Portland Boat Works Inc

Portland Boat Works, located just east of the Arrigoni Bridge in Portland on the Connecticut River, is a full service, NMMA Certified, facility specializing in the service, restoration and general maintenance of larger yachts. Seven heated work bays enable year-round service to boats up to 68 feet. A highly skilled and experienced service team is available to address your engine maintenance, repair or re-powering needs, as well as electronic installations, finish carpentry, fiberglass finishing and repair, painting and varnishing. Portland uses two Brownell self-propelled trailers to haul and launch boats up to 60 tons safely and efficiently. PBW stores most of its estimated 120 customer vessels in storage sheds, but outside storage and shrink-wrapping is available as well. Summer slips are available for seasonal rental with key access showers and bathrooms for the boater’s convenience. One of the best maintained launch ramps in the area is available for a per use fee or an affordable seasonal rate. Seasonal launch purchasers also have the option of leaving their boats parked on trailers near the ramp for the season for an additional fee. A marine store on the premises will provide the basic boating needs for your convenience. Picnic tables and a gazebo offer our customers and visitors a comfortable place to enjoy the ever-changing Connecticut River vistas all summer long.
