Performance Done Right
At South Bay we didn’t invent precision, we didn’t invent power and we didn’t invent performance. We just put them together better than anyone else.

1) Forest River Marine Pontoon TubesMore strength for longer life in extreme water conditions.
2) Performance Skin Roll formed for better water & air flow to maximize performance and efficiency.
3) Lifting Strakes Quicker planing for added maneuverability and a smooth ride.
4) Nose Cones 52” nose cone rather than 48” industry standard increases speed and reduces fuel consumption.
5) PAD Running Surface
6) Splash Fins
7) Bulk Head Strategically placed bulkheads at vital points in the pontoon provide superior structural integrity.
8) Spray Rails
