The South Bay 529CR Upper Deck 2011 is the longer of the two at 29,0 feet overall. The South Bay 927CPTR TT I/O 2008 comes in at 28,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Both the South Bay 529CR Upper Deck 2011 and South Bay 927CPTR TT I/O 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.

The South Bay 927CPTR TT I/O 2008 has the bigger tank at 39 gallons, versus 31 gallons on the South Bay 529CR Upper Deck 2011. That 8-gallon difference translates to roughly 24–40 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

South Bay 529CR Upper Deck 2011 vs South Bay 927CPTR TT I/O 2008 — Same Brand, Different Boat

The South Bay 529CR Upper Deck 2011 vs South Bay 927CPTR TT I/O 2008 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The power gap is worth calling out. Rated to 525 hp, the South Bay 927CPTR TT I/O 2008 has a 375-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 927CPTR TT I/O 2008 carries 39 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.

The South Bay 927CPTR TT I/O 2008 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The South Bay 529CR Upper Deck 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: Performance buyers should lean toward the South Bay 927CPTR TT I/O 2008 and its 525-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.
