South Bay 529CR Upper Deck TT 2011 vs South Bay 724SL TT 2013 — Which Pontoon Fits Your Needs?

When two boats share the same hull type — in this case both the South Bay 529CR Upper Deck TT 2011 and the South Bay 724SL 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 724SL TT 2013 has a 75-hp advantage over the South Bay 529CR Upper Deck TT 2011's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Bottom line: The South Bay 529CR Upper Deck TT 2011 at 29,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The South Bay 724SL TT 2013 at 25,6 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

South Bay 529CR Upper Deck TT 2011 vs South Bay 724SL TT 2013 — Common Questions

Which is the larger boat — the South Bay 529CR Upper Deck TT 2011 or the South Bay 724SL TT 2013?
The South Bay 529CR Upper Deck TT 2011 is the longer of the two at 29,0 feet overall. The South Bay 724SL TT 2013 comes in at 25,6 feet, making it roughly 3,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The South Bay 724SL TT 2013 is rated to a maximum of 300 hp, giving it the larger power ceiling. The South Bay 529CR Upper Deck TT 2011 tops out at 225 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many passengers can the South Bay 724SL TT 2013 carry?
The South Bay 724SL TT 2013 has an official capacity rating of 15 people. Capacity data wasn't available for the other model in this comparison — verify directly with the dealer.
Do these boats require an oversize trailer permit to tow on US highways?
Both the South Bay 529CR Upper Deck TT 2011 and South Bay 724SL TT 2013 share an 8 ft. 6 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Are the South Bay 529CR Upper Deck TT 2011 and South Bay 724SL TT 2013 from the same manufacturer?
Yes — both the South Bay 529CR Upper Deck TT 2011 and the South Bay 724SL TT 2013 are built by South Bay. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
