The 2026 Shoalwater 21 Cat is a fiberglass catamaran built for shallow-water fishing. Its twin-hull design delivers stability and maneuverability suited to inshore and bay conditions, whether targeting flats or open water. The boat spans 21 feet in length with an 8.67-foot beam and runs a single 175-horsepower Yamaha outboard.
The boat is outfitted 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. Hydraulic tilt steering and a Jack plate allow precise handling in shallow water, while Lenco trim tabs help manage trim and performance. The cabin incorporates fiberglass hatches for storage access.
Fuel capacity is 61 gallons, supporting extended time on the water. This is a new model year boat ready for delivery.
