2026 Yellowfin 21 Bay

The 2026 Yellowfin 21 Bay is a high-performance bay boat built on Yellowfin's signature stepped hull design, engineered for speed, stability, and shallow-water fishing. Powered by a 200 hp Mercury four-stroke engine, it reaches top speeds exceeding 55 mph while maintaining fuel efficiency at cruise speeds of 30–31 mph. The stepped hull creates an aerated water cushion for a smooth ride and quick acceleration, planing in seconds and hitting 30 mph in roughly six seconds. With a draft just over one foot, the boat accesses very shallow waters while holding its course predictably through turns without sliding.

The fishing layout maximizes angler capability with spacious elevated casting platforms forward and aft, three round livewells on the aft deck for bait storage, and abundant storage throughout—including a large insulated fish box in the bow step and sealed compartments under the forward deck. The elevated center console accommodates a 15-inch multi-function display and offers both standing and sitting positions. Rod holders, secure non-skid surfaces, and a hull design that minimizes fish-spooking noise reflect careful attention to detail.

Construction follows Yellowfin's standards for quality, with high-grade materials throughout. Standard equipment includes a jack plate, Power-Pole shallow-water anchor, and a custom AmeraTrail aluminum trailer with spare tire. Premium hardware such as Gemlux cleats and O-ring gutter systems prevent water intrusion. At 21 feet 9 inches long with a 7-foot-9-inch beam and 50-gallon fuel capacity, the boat is purpose-built for serious inshore and nearshore anglers.
