The 2026 Shoalwater 21 Cat is a fiberglass catamaran built for shallow-water fishing. Its twin-hull design delivers stability and maneuverability across flats and bays, while the compact 21-foot length and 8.67-foot beam allow easy navigation of tight waterways. Power comes from a single 175 hp Yamaha engine.
The boat is fitted with practical fishing features including dual live wells with aerators, a leaning post with four rod holders, and a tall grab rail with cup holders—all powder coated for durability. A Jack plate offers engine positioning flexibility, and Lenco trim tabs aid in handling across varying water conditions. Hydraulic tilt steering and fiberglass hatches round out the package.
