20’ Pumpout Boats Built for Stability, Safety & Long-Term Performance

20’ Pumpout Boats from Marine Boatbuilders represent our third-generation design, refined through decades of real-world experience building pumpout boats, work boats, and patrol boats. Every 20’ pumpout boat is engineered for maximum stability, simple operation, and uncompromising safety, with an all-composite construction—no wood anywhere in the hull, deck, stringers, or transom.

Advanced Modified V Hull Design

Our proprietary PUMPOUT® hull features a concave bottom, not convex like most boats. This design delivers superior stability, smoother handling, and eliminates yaw in following seas—critical for pumpout operations in tight or rough conditions.

• Hand-laid woven roving and gun roving construction

• All fiberglass is marine-grade E-glass

• Thermoset polyester resin throughout

• ISO NPG thermoset gelcoat (approx. 1.5 mm thick)

• 10° deadrise at the stern for quick planing

• Composite laminate transom: 3” total thickness

• No wood in the transom—ever

Our state-of-the-art U-channel fiberglass stringer system provides exceptional rigidity and longevity without the risk of rot or water intrusion.

Deck & Floor Construction

The deck and floor are fully composite and designed for durability, drainage, and crew safety.
