Detailed Evaluation & Buyer Recommendation

South Bay 529CR Upper Deck 2011 vs South Bay 925Sport TT 2013 — A Close Look at Two Pontoons

When two boats share the same hull type — in this case both the South Bay 529CR Upper Deck 2011 and the South Bay 925Sport TT 2013 are pontoon designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

The power gap is worth calling out. Rated to 300 hp, the South Bay 925Sport TT 2013 has a 150-hp advantage over the South Bay 529CR Upper Deck 2011's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
