2025 South Bay 523UL 3.0+ — Pontoon Boat

Brand new and built for those who refuse to compromise on performance or comfort. The South Bay 523UL 3.0+ is a premium, triple-tube performance pontoon that redefines what a pontoon boat is capable of. This is not your average lake cruiser — the 3.0+ designation means you’re getting South Bay’s top-tier triple-log underpinning, delivering a ride that is faster, more stable, and more responsive than anything a standard pontoon can offer.

Backed by a Mercury 300HP engine — serious power for a serious pontoon. This combination pushes the 523UL into performance territory that will surprise anyone who thinks they know what a pontoon can do. Fast, smooth, and confidence-inspiring at speed.

• GPS — navigate any body of water with precision and confidence
• Sonar — know what’s beneath you whether you’re fishing or finding the perfect anchoring spot
