31' Pumpout Boats | 31 Ft Custom Made Pumpout Boat by Marine Boatbuilders Company   401-732-1975

Marine Boatbuilders Company specializes in designing and manufacturing custom made Pump Kleen® 31' pumpout boats. Our 31 foot pumpout boats are built for safety, simplicity and stability. Our unique PUMP KLEEN® System offers many benefits over our competitor's pumpout boats. In addition, our boats are not made with wood, not in the hull, not in the deck, not in the transom.

Modified V Hull Design - 31' Pumpout Boat

The hull is constructed with a combination of hand laid woven, roving, and gun roving. All fiberglass is "E" glass and the resin is thermo set polyester. The gelcoat is ISO NPG thermo set gelcoat, normally 0.30" thick. Our boat has a 21-degree dead rise at the stern, and a 12-degree transom angle. The hull transom is a composite laminate 2" thick, and 1" fiberglass a total of 3" thick. There is no wood in the transom.

Stringer System - 31' Pumpout Boat

Our stringer system is a U channel all fiberglass state of the art system. There is no wood in our stringer system.

Deck, Floor - 31' Pumpout Boat

The deck is a combination of hand laid woven, roving, and gun roving. Fiberglass "E" glass applied and the resin is thermostat gelcoat (white). Deck has a 12" step up in the bow area that is 48" long. It includes two forward large stowage areas with fiberglass hatches. The deck is free from any pumps, vents, or pipes of any kind leaving much-needed extra workspace, and NO trip hazards. Our floor is fiberglass composite, not wood like other boats there is NO wood in our deck, floor or in our boat. The deck is finished with non-skid on horizontal surfaces. Our deck is self-bailing at all times; weather containment cell is full or empty.

Two-part thermostat foam is injected between the floor and hull in areas not occupied by tankage and other equipment.

Cloth. Our containment cell has 5 athwartship baffles. The Edson pump that runs the sewage tank is located completely under the center console.
