2026 Shoalwater 21' Catamaran

This 2026 Shoalwater 21-foot catamaran is a fiberglass flats boat built for shallow-water operation. The hull spans 8 feet 8 inches across the beam, giving the boat a stable platform well-suited to coastal and bay fishing. Power comes from a single 175-horsepower gasoline engine.

The catamaran's twin-hull design delivers the shallow draft and maneuverability characteristic of the Shoalwater line. The open layout provides working space across the deck, making it practical for anglers and water enthusiasts alike.
