South Bay 8520CR 2007 vs South Bay 927CR TT 2009 — Same Brand, Different Boat

The South Bay 8520CR 2007 vs South Bay 927CR TT 2009 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 927CR TT 2009 measures 28,0 feet overall (2009), giving it roughly 7,0 additional feet of deck space compared to the South Bay 8520CR 2007 at 21,0 feet (2007). Weight tells a clearer story for trailering families: the South Bay 927CR TT 2009 tips the scales at 3 055 lbs — 880 lbs less than the South Bay 8520CR 2007 at 2 175 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 275 hp, the South Bay 927CR TT 2009 has a 185-hp advantage over the South Bay 8520CR 2007's 90-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 927CR TT 2009 carries 54 gallons versus 29 gallons in the South Bay 8520CR 2007. 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 927CR TT 2009 is rated for 18 passengers, while the South Bay 8520CR 2007 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 927CR TT 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The South Bay 927CR TT 2009 comes in at 11 lbs per hp versus 24 lbs per hp for the South Bay 8520CR 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 8520CR 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The South Bay 927CR TT 2009 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 927CR TT 2009 if your priority is putting more people on the water — it handles 18 passengers and at 28,0 ft it has the deck room to back that rating up comfortably. The South Bay 8520CR 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.

South Bay 8520CR 2007 vs South Bay 927CR TT 2009 — Common Questions

Which is the larger boat — the South Bay 8520CR 2007 or the South Bay 927CR TT 2009?
The South Bay 927CR TT 2009 is the longer of the two at 28,0 feet overall. The South Bay 8520CR 2007 comes in at 21,0 feet, making it roughly 7,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the South Bay 8520CR 2007 or the South Bay 927CR TT 2009?
For trailering, the South Bay 8520CR 2007 has the edge at 2 175 lbs dry weight versus 3 055 lbs for the South Bay 927CR TT 2009. 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 927CR TT 2009 is rated to a maximum of 275 hp, giving it the larger power ceiling. The South Bay 8520CR 2007 tops out at 90 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 8520CR 2007 is Coast Guard rated for 10 passengers, while the South Bay 927CR TT 2009 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 8520CR 2007 and South Bay 927CR TT 2009 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 8520CR 2007 or the South Bay 927CR TT 2009?
The South Bay 927CR TT 2009 has the bigger tank at 54 gallons, versus 29 gallons on the South Bay 8520CR 2007. That 25-gallon difference translates to roughly 75–125 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the South Bay 8520CR 2007 and South Bay 927CR TT 2009 from the same manufacturer?
Yes — both the South Bay 8520CR 2007 and the South Bay 927CR TT 2009 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.
