When two boats share the same hull type — in this case both the South Bay 522CR 2011 and the South Bay 625CR 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 522CR 2011 at 23,6 ft versus South Bay 625CR TT I/O 2009 at 26,0 ft. Weight tells a clearer story for trailering families: the South Bay 625CR TT I/O 2009 tips the scales at 292 lbs — 274 lbs less than the South Bay 522CR 2011 at 18 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 300 hp, the South Bay 625CR TT I/O 2009 has a 150-hp advantage over the South Bay 522CR 2011's 150-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 29 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The South Bay 625CR TT I/O 2009 is rated for 15 passengers, while the South Bay 522CR 2011 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the South Bay 625CR 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 625CR TT I/O 2009 if your priority is putting more people on the water — it handles 15 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The South Bay 522CR 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
