When two boats share the same hull type — in this case both the South Bay 422CR - 25 in. Upgrade 2011 and the South Bay 722SL 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 422CR - 25 in. Upgrade 2011 at 21,6 ft versus South Bay 722SL TT 2011 at 22,8 ft. Weight tells a clearer story for trailering families: the South Bay 422CR - 25 in. Upgrade 2011 tips the scales at 1 755 lbs — 1 501 lbs more than the South Bay 722SL TT 2011 at 254 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 225 hp, the South Bay 722SL TT 2011 has a 135-hp advantage over the South Bay 422CR - 25 in. Upgrade 2011's 90-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 12 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.
