When two boats share the same hull type — in this case both the South Bay 722CLR 2010 and the South Bay 820CR 2008 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?

Size is the most obvious dividing line here. The South Bay 722CLR 2010 measures 24,4 feet overall (2010), giving it roughly 3,4 additional feet of deck space compared to the South Bay 820CR 2008 at 21,0 feet (2008). Weight tells a clearer story for trailering families: the South Bay 820CR 2008 tips the scales at 2 175 lbs — 2 152 lbs less than the South Bay 722CLR 2010 at 23 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 115 hp, the South Bay 722CLR 2010 has a 25-hp advantage over the South Bay 820CR 2008'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 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 722CLR 2010 is rated for 12 passengers, while the South Bay 820CR 2008 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the South Bay 722CLR 2010 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.
