21′ Patrol Boats

Custom Made 21 ‘ Patrol Boats

Our 23′ Patrol Boat is built and designed from our years of experience building Patrol boats and Pumpout boats. Our boats are built for safety, simplicity, and stability and are designed to be efficient, fast, smooth-riding, and virtually maintenance free.

Modified V Hull Design

Our boat hull bottom is concave not convex like most hulls. This allows for maximum stability, and ease of handling. Our boat because of its design will not yaw in a following sea. The hull is constructed with a combination of hand laid woven, roving, and gun roving. All fiberglasses are “E” glass and the resin is thermoset polyester. The gelcoat is ISO NPG thermo set gel coat, normally 1.5″ thick. Our boat has a 10-degree dead rise at the stern, which allow the boat quickly. The hull transom is a composite laminate 1.5″ thick, a total of 3″ thick. There is no wood in the transom.

Stringer System

Our stringer system is a U channels all fiberglass state of the art system. There is no wood in our stringer system. This is a far superior design compared to the wooden fir, or other wood stringer design compared with fiberglass used by our competition.

Deck and Floor

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. Our floor is fiberglass composite, not wood like other boats there is NO wood in our deck, floor or in our boat.

Foamed Flotation

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

Quality Gelcoat

Only storm and blister resistant gelcoat are used to form the skin of each boat, a wide variety of colors are available. White is our standard color included in the quote price; other color choices would be extra cost.

Fuel Tank

The fuel tank is 124 gallons and located below the deck.
