South Bay 518CR B 2013 vs South Bay 725CR TT 2012 - Boat Spec Comparison

Q: Which is the larger boat — the South Bay 518CR B 2013 or the South Bay 725CR TT 2012?

The South Bay 725CR TT 2012 is the longer of the two at 27,8 feet overall. The South Bay 518CR B 2013 comes in at 20,6 feet, making it roughly 7,2 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The South Bay 725CR TT 2012 is rated to a maximum of 300 hp, giving it the larger power ceiling. The South Bay 518CR B 2013 tops out at 115 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.

Q: How many people can each boat hold?

The South Bay 518CR B 2013 is Coast Guard rated for 6 passengers, while the South Bay 725CR TT 2012 is certified for 17. 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.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the South Bay 518CR B 2013 and South Bay 725CR TT 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.

Q: Are the South Bay 518CR B 2013 and South Bay 725CR TT 2012 from the same manufacturer?

Yes — both the South Bay 518CR B 2013 and the South Bay 725CR TT 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.

Detailed Evaluation & Buyer Recommendation

South Bay 518CR B 2013 vs South Bay 725CR TT 2012 — Which Pontoon Fits Your Needs?

When two boats share the same hull type — in this case both the South Bay 518CR B 2013 and the South Bay 725CR TT 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?

The power gap is worth calling out. Rated to 300 hp, the South Bay 725CR TT 2012 has a 185-hp advantage over the South Bay 518CR B 2013's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The South Bay 725CR TT 2012 is rated for 17 passengers, while the South Bay 518CR B 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the South Bay 725CR TT 2012 could be the deciding factor.

Bottom line: Choose the South Bay 725CR TT 2012 if your priority is putting more people on the water — it handles 17 passengers and at 27,8 ft it has the deck room to back that rating up comfortably. The South Bay 518CR B 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
