South Bay 925E TT 2012 vs South Bay 928SL TT I/O 2011 — A Close Look at Two Pontoons

When two boats share the same hull type — in this case both the South Bay 925E TT 2012 and the South Bay 928SL TT I/O 2011 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 925E TT 2012 at 27,8 ft versus South Bay 928SL TT I/O 2011 at 28,2 ft. At 4 lbs and 38 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 300 hp for the South Bay 925E TT 2012 and 300 hp for the South Bay 928SL TT I/O 2011. 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 928SL TT I/O 2011 carries 51 gallons versus 27 gallons in the South Bay 925E TT 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 16 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.

Bottom line: The South Bay 925E TT 2012 and South Bay 928SL TT I/O 2011 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

South Bay 925E TT 2012 vs South Bay 928SL TT I/O 2011 — Common Questions

Which is the larger boat — the South Bay 925E TT 2012 or the South Bay 928SL TT I/O 2011?
The South Bay 928SL TT I/O 2011 is the longer of the two at 28,2 feet overall. The South Bay 925E TT 2012 comes in at 27,8 feet, making it roughly 0,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the South Bay 925E TT 2012 or the South Bay 928SL TT I/O 2011?
For trailering, the South Bay 925E TT 2012 has the edge at 4 lbs dry weight versus 38 lbs for the South Bay 928SL TT I/O 2011. 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 925E TT 2012 is Coast Guard rated for 16 passengers, while the South Bay 928SL TT I/O 2011 is certified for 16. 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 925E TT 2012 and South Bay 928SL TT I/O 2011 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 925E TT 2012 or the South Bay 928SL TT I/O 2011?
The South Bay 928SL TT I/O 2011 has the bigger tank at 51 gallons, versus 27 gallons on the South Bay 925E TT 2012. That 24-gallon difference translates to roughly 72–120 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the South Bay 925E TT 2012 and South Bay 928SL TT I/O 2011 from the same manufacturer?
Yes — both the South Bay 925E TT 2012 and the South Bay 928SL TT I/O 2011 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.
