The 2026 Shoalwater 21 Cat is a fiberglass catamaran built for shallow-water fishing. At 21 feet 8 inches with an 8.5-foot beam, its twin-hull design provides stability and excellent maneuverability in skinny water. Powered by a 175 horsepower Yamaha outboard, the boat reaches fishing grounds efficiently while maintaining the shallow draft needed for flats work.
The boat is rigged with fishing-focused equipment throughout. It features dual live wells with pro-grade aeration, a leaning post with cushion, and a stainless steel stand-up burn bar with cup holders. Hydraulic tilt steering and Lenco trim tabs give you responsive control across variable bottom conditions. The engine sits on a Bob's jack plate for additional draft adjustment, and a spare tire is included.
Hull finish is white with charcoal accents. The boat comes ready for immediate use on inshore waters, bays, and flats.
