South Bay 522F TT 2010 vs South Bay 925CPTR TT I/O 2008 — Same Brand, Different Boat

The South Bay 522F TT 2010 vs South Bay 925CPTR TT I/O 2008 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.

On paper these two are close siblings in the size department — South Bay 522F TT 2010 at 24,0 ft versus South Bay 925CPTR TT I/O 2008 at 26,0 ft. Weight tells a clearer story for trailering families: the South Bay 925CPTR TT I/O 2008 tips the scales at 3 125 lbs — 2 913 lbs less than the South Bay 522F TT 2010 at 212 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 925CPTR TT I/O 2008 has a 300-hp advantage over the South Bay 522F TT 2010's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the South Bay 925CPTR TT I/O 2008 carries 39 gallons versus 31 gallons in the South Bay 522F TT 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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.

At this size, power-to-weight ratio matters more than outright horsepower. The South Bay 522F TT 2010 comes in at 1 lbs per hp versus 6 lbs per hp for the South Bay 925CPTR TT I/O 2008. 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 925CPTR TT I/O 2008 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The South Bay 522F TT 2010 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: Performance buyers should lean toward the South Bay 925CPTR TT I/O 2008 and its 525-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the South Bay 522F TT 2010 with its 225-hp rating is the more economical daily driver.

South Bay 522F TT 2010 vs South Bay 925CPTR TT I/O 2008 — Common Questions

Which is the larger boat — the South Bay 522F TT 2010 or the South Bay 925CPTR TT I/O 2008?
The South Bay 925CPTR TT I/O 2008 is the longer of the two at 26,0 feet overall. The South Bay 522F TT 2010 comes in at 24,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the South Bay 522F TT 2010 or the South Bay 925CPTR TT I/O 2008?
For trailering, the South Bay 522F TT 2010 has the edge at 212 lbs dry weight versus 3 125 lbs for the South Bay 925CPTR TT I/O 2008. 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.
Which boat can handle a bigger outboard?
The South Bay 925CPTR TT I/O 2008 is rated to a maximum of 525 hp, giving it the larger power ceiling. The South Bay 522F TT 2010 tops out at 225 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The South Bay 522F TT 2010 is Coast Guard rated for 14 passengers, while the South Bay 925CPTR TT I/O 2008 is certified for 14. 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 522F TT 2010 and South Bay 925CPTR TT I/O 2008 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.
Which boat has the larger fuel tank — the South Bay 522F TT 2010 or the South Bay 925CPTR TT I/O 2008?
The South Bay 925CPTR TT I/O 2008 has the bigger tank at 39 gallons, versus 31 gallons on the South Bay 522F TT 2010. That 8-gallon difference translates to roughly 24–40 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the South Bay 522F TT 2010 and South Bay 925CPTR TT I/O 2008 from the same manufacturer?
Yes — both the South Bay 522F TT 2010 and the South Bay 925CPTR TT I/O 2008 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.
