When two boats share the same hull type — in this case both the South Bay 722CR TT 2010 and the South Bay 725CRO TT I/O 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 722CR TT 2010 at 24,8 ft versus South Bay 725CRO TT I/O 2011 at 22,4 ft. Weight tells a clearer story for trailering families: the South Bay 722CR TT 2010 tips the scales at 261 lbs — 230 lbs more than the South Bay 725CRO TT I/O 2011 at 31 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 725CRO TT I/O 2011 has a 225-hp advantage over the South Bay 722CR TT 2010's 300-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.
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.
One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 25" diameter. That shared spec means stability and buoyancy characteristics are closely matched — the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
Bottom line: The South Bay 722CR TT 2010 at 24,8 ft is the right call if deck space, comfort, and entertaining are top of your list. The South Bay 725CRO TT I/O 2011 at 22,4 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
