The 2022 Sweetwater 2186 C4 is a 21-foot pontoon built on an aluminum hull and powered by a single Yamaha F115LB gasoline engine. The four-gate design provides easy boarding access across multiple points on the deck, while the 8.5-foot beam delivers a stable platform for cruising on lakes and calm waters.
The layout centers on a captain's chair with a swivel base, slider mechanism, and fold-down arms mounted on a 10-inch fixed pedestal. A tilt steering wheel is fitted for easier helm operation. The pontoon includes a depth and fish finder—a Hook Reveal 5 model—useful for navigating and locating structure below.
The boat features navy canvas, metallic navy rail skin, and gray interior with navy vinyl accents throughout. Yamaha pre-rigging was completed at the factory, preparing the engine and related systems for immediate use. The aluminum construction and modest 115-horsepower motor make this an efficient, manageable platform for recreational boating.
