When two boats share the same hull type — in this case both the South Bay 522CPTR TT 2011 and the South Bay 525CR 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 522CPTR TT 2011 at 24,0 ft versus South Bay 525CR TT I/O 2009 at 26,0 ft. At 216 lbs and 263 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 225 hp, the South Bay 522CPTR TT 2011 has a 90-hp advantage over the South Bay 525CR TT I/O 2009's 135-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 31 gal and 31 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The South Bay 525CR TT I/O 2009 is rated for 16 passengers, while the South Bay 522CPTR TT 2011 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the South Bay 525CR TT I/O 2009 could be the deciding factor.
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: Choose the South Bay 525CR TT I/O 2009 if your priority is putting more people on the water — it handles 16 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The South Bay 522CPTR TT 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 15 that costs less to run day-to-day.
