When two boats share the same hull type — in this case both the South Bay 522FC TT I/O 2011 and the South Bay 622CR-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 522FC TT I/O 2011 at 23,4 ft versus South Bay 622CR-O 2009 at 23,0 ft. At 246 lbs and 214 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 220 hp, the South Bay 522FC TT I/O 2011 has a 105-hp advantage over the South Bay 622CR-O 2009's 115-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 522FC TT I/O 2011 is rated for 15 passengers, while the South Bay 622CR-O 2009 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the South Bay 522FC TT I/O 2011 could be the deciding factor.

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.
