South Bay 522CPTR 2011 vs South Bay 930CR 2007 — Same Brand, Different Boat

The South Bay 522CPTR 2011 vs South Bay 930CR 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The South Bay 930CR 2007 measures 31,0 feet overall (2007), giving it roughly 7,4 additional feet of deck space compared to the South Bay 522CPTR 2011 at 23,6 feet (2011). Weight tells a clearer story for trailering families: the South Bay 930CR 2007 tips the scales at 343 lbs — 325 lbs less than the South Bay 522CPTR 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.

Both boats share a closely matched power ceiling — 150 hp for the South Bay 522CPTR 2011 and 150 hp for the South Bay 930CR 2007. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. 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 930CR 2007 is rated for 18 passengers, while the South Bay 522CPTR 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 930CR 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The South Bay 522CPTR 2011 comes in at 0 lbs per hp versus 2 lbs per hp for the South Bay 930CR 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

The South Bay 930CR 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The South Bay 522CPTR 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: Choose the South Bay 930CR 2007 if your priority is putting more people on the water — it handles 18 passengers and at 31,0 ft it has the deck room to back that rating up comfortably. The South Bay 522CPTR 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.

South Bay 522CPTR 2011 vs South Bay 930CR 2007 — Common Questions

Which is the larger boat — the South Bay 522CPTR 2011 or the South Bay 930CR 2007?
The South Bay 930CR 2007 is the longer of the two at 31,0 feet overall. The South Bay 522CPTR 2011 comes in at 23,6 feet, making it roughly 7,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the South Bay 522CPTR 2011 or the South Bay 930CR 2007?
For trailering, the South Bay 522CPTR 2011 has the edge at 18 lbs dry weight versus 343 lbs for the South Bay 930CR 2007. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The South Bay 522CPTR 2011 is Coast Guard rated for 13 passengers, while the South Bay 930CR 2007 is certified for 18. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the South Bay 522CPTR 2011 and South Bay 930CR 2007 share an 8 ft. 6 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the South Bay 522CPTR 2011 and South Bay 930CR 2007?
Both boats carry similar fuel loads — 31 gallons and 29 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the South Bay 522CPTR 2011 and South Bay 930CR 2007 from the same manufacturer?
Yes — both the South Bay 522CPTR 2011 and the South Bay 930CR 2007 are built by South Bay. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
