South Bay 522CLR 2011 vs South Bay 722CPTR TT I/O 2012 — A Close Look at Two Pontoons

When two boats share the same hull type — in this case both the South Bay 522CLR 2011 and the South Bay 722CPTR TT I/O 2012 are pontoon designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — South Bay 522CLR 2011 at 23,6 ft versus South Bay 722CPTR TT I/O 2012 at 25,4 ft. Weight tells a clearer story for trailering families: the South Bay 722CPTR TT I/O 2012 tips the scales at 266 lbs — 248 lbs less than the South Bay 522CLR 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.

The power gap is worth calling out. Rated to 300 hp, the South Bay 722CPTR TT I/O 2012 has a 150-hp advantage over the South Bay 522CLR 2011's 150-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 522CLR 2011 carries 31 gallons versus 27 gallons in the South Bay 722CPTR TT I/O 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 13 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.

Both are 2-tube and 3-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.

Bottom line: Performance buyers should lean toward the South Bay 722CPTR TT I/O 2012 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the South Bay 522CLR 2011 with its 150-hp rating is the more economical daily driver.

South Bay 522CLR 2011 vs South Bay 722CPTR TT I/O 2012 — Common Questions

Which is the larger boat — the South Bay 522CLR 2011 or the South Bay 722CPTR TT I/O 2012?
The South Bay 722CPTR TT I/O 2012 is the longer of the two at 25,4 feet overall. The South Bay 522CLR 2011 comes in at 23,6 feet, making it roughly 1,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the South Bay 522CLR 2011 or the South Bay 722CPTR TT I/O 2012?
For trailering, the South Bay 522CLR 2011 has the edge at 18 lbs dry weight versus 266 lbs for the South Bay 722CPTR TT I/O 2012. 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 722CPTR TT I/O 2012 is rated to a maximum of 300 hp, giving it the larger power ceiling. The South Bay 522CLR 2011 tops out at 150 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 522CLR 2011 is Coast Guard rated for 13 passengers, while the South Bay 722CPTR TT I/O 2012 is certified for 13. 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 522CLR 2011 and South Bay 722CPTR TT I/O 2012 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 522CLR 2011 or the South Bay 722CPTR TT I/O 2012?
The South Bay 522CLR 2011 has the bigger tank at 31 gallons, versus 27 gallons on the South Bay 722CPTR TT I/O 2012. That 4-gallon difference translates to roughly 12–20 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the South Bay 522CLR 2011 and South Bay 722CPTR TT I/O 2012 from the same manufacturer?
Yes — both the South Bay 522CLR 2011 and the South Bay 722CPTR TT I/O 2012 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.
