When two boats share the same hull type — in this case both the South Bay 522RS TT 2013 and the South Bay 522SLX TT 2011 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 522SLX TT 2011 at 24,0 ft. At 251 lbs and 234 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 300 hp, the South Bay 522RS TT 2013 has a 75-hp advantage over the South Bay 522SLX TT 2011's 225-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 522RS TT 2013 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the South Bay 522SLX TT 2011 with its 225-hp rating is the more economical daily driver.
