When two boats share the same hull type — in this case both the South Bay 522RS TT 2013 and the South Bay 925CR TT I/O 2009 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?
On paper these two are close siblings in the size department — South Bay 522RS TT 2013 at 24,0 ft versus South Bay 925CR TT I/O 2009 at 26,0 ft. Weight tells a clearer story for trailering families: the South Bay 925CR TT I/O 2009 tips the scales at 3 125 lbs — 2 874 lbs less than the South Bay 522RS TT 2013 at 251 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 525 hp, the South Bay 925CR TT I/O 2009 has a 225-hp advantage over the South Bay 522RS TT 2013's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 14 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the South Bay 925CR TT I/O 2009 and its 525-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the South Bay 522RS TT 2013 with its 300-hp rating is the more economical daily driver.
