South Bay 725CR TT I/O 2010 vs South Bay 925CPTR TT I/O 2007 — Same Brand, Different Boat

The South Bay 725CR TT I/O 2010 vs South Bay 925CPTR TT I/O 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.

On paper these two are close siblings in the size department — South Bay 725CR TT I/O 2010 at 26,3 ft versus South Bay 925CPTR TT I/O 2007 at 26,0 ft. Weight tells a clearer story for trailering families: the South Bay 925CPTR TT I/O 2007 tips the scales at 3 125 lbs — 2 830 lbs less than the South Bay 725CR TT I/O 2010 at 295 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 — 525 hp for the South Bay 725CR TT I/O 2010 and 525 hp for the South Bay 925CPTR TT I/O 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. Fuel capacity breaks the other way: the South Bay 925CPTR TT I/O 2007 carries 39 gallons versus 31 gallons in the South Bay 725CR TT I/O 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The South Bay 725CR TT I/O 2010 is rated for 14 passengers, while the South Bay 925CPTR TT I/O 2007 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 725CR TT I/O 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The South Bay 725CR TT I/O 2010 comes in at 1 lbs per hp versus 6 lbs per hp for the South Bay 925CPTR TT I/O 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 925CPTR TT I/O 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The South Bay 725CR TT I/O 2010 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 725CR TT I/O 2010 if your priority is putting more people on the water — it handles 14 passengers and at 26,3 ft it has the deck room to back that rating up comfortably. The South Bay 925CPTR TT I/O 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.

South Bay 725CR TT I/O 2010 vs South Bay 925CPTR TT I/O 2007 — Common Questions

Which is the larger boat — the South Bay 725CR TT I/O 2010 or the South Bay 925CPTR TT I/O 2007?
The South Bay 725CR TT I/O 2010 is the longer of the two at 26,3 feet overall. The South Bay 925CPTR TT I/O 2007 comes in at 26,0 feet, making it roughly 0,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the South Bay 725CR TT I/O 2010 or the South Bay 925CPTR TT I/O 2007?
For trailering, the South Bay 725CR TT I/O 2010 has the edge at 295 lbs dry weight versus 3 125 lbs for the South Bay 925CPTR TT I/O 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 725CR TT I/O 2010 is Coast Guard rated for 14 passengers, while the South Bay 925CPTR TT I/O 2007 is certified for 12. 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 725CR TT I/O 2010 and South Bay 925CPTR TT I/O 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.
Which boat has the larger fuel tank — the South Bay 725CR TT I/O 2010 or the South Bay 925CPTR TT I/O 2007?
The South Bay 925CPTR TT I/O 2007 has the bigger tank at 39 gallons, versus 31 gallons on the South Bay 725CR TT I/O 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 725CR TT I/O 2010 and South Bay 925CPTR TT I/O 2007 from the same manufacturer?
Yes — both the South Bay 725CR TT I/O 2010 and the South Bay 925CPTR TT I/O 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.
