The South Bay 925CR TT 2011 vs South Bay 930CR 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.
Size is the most obvious dividing line here. The South Bay 930CR TT I/O 2007 measures 31,0 feet overall (2007), giving it roughly 3,3 additional feet of deck space compared to the South Bay 925CR TT 2011 at 27,8 feet (2011). Weight tells a clearer story for trailering families: the South Bay 925CR TT 2011 tips the scales at 2 925 lbs — 2 539 lbs more than the South Bay 930CR TT I/O 2007 at 386 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 930CR TT I/O 2007 has a 225-hp advantage over the South Bay 925CR TT 2011's 300-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 925CR TT 2011 carries 54 gallons versus 39 gallons in the South Bay 930CR TT I/O 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 17 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 930CR TT I/O 2007 comes in at 1 lbs per hp versus 10 lbs per hp for the South Bay 925CR TT 2011. 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 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 925CR TT 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The South Bay 930CR TT I/O 2007 at 31,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The South Bay 925CR TT 2011 at 27,8 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
