South Bay 529CR Upper Deck 2011 vs South Bay 925CLR TT 2008 — 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 925CLR TT 2008 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 275 hp, the South Bay 925CLR TT 2008 has a 125-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. Fuel capacity breaks the other way: the South Bay 925CLR TT 2008 carries 38 gallons versus 31 gallons in the South Bay 529CR Upper Deck 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both are 2-tube and 3-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.

Bottom line: Performance buyers should lean toward the South Bay 925CLR TT 2008 and its 275-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the South Bay 529CR Upper Deck 2011 with its 150-hp rating is the more economical daily driver.

South Bay 529CR Upper Deck 2011 vs South Bay 925CLR TT 2008 — Common Questions

Which is the larger boat — the South Bay 529CR Upper Deck 2011 or the South Bay 925CLR TT 2008?
The South Bay 529CR Upper Deck 2011 is the longer of the two at 29,0 feet overall. The South Bay 925CLR TT 2008 comes in at 27,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The South Bay 925CLR TT 2008 is rated to a maximum of 275 hp, giving it the larger power ceiling. The South Bay 529CR Upper Deck 2011 tops out at 150 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 925CLR TT 2008 carry?
The South Bay 925CLR TT 2008 has an official capacity rating of 17 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 2011 and South Bay 925CLR TT 2008 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.
Which boat has the larger fuel tank — the South Bay 529CR Upper Deck 2011 or the South Bay 925CLR TT 2008?
The South Bay 925CLR TT 2008 has the bigger tank at 38 gallons, versus 31 gallons on the South Bay 529CR Upper Deck 2011. That 7-gallon difference translates to roughly 21–35 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the South Bay 529CR Upper Deck 2011 and South Bay 925CLR TT 2008 from the same manufacturer?
Yes — both the South Bay 529CR Upper Deck 2011 and the South Bay 925CLR TT 2008 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.
