When two boats share the same hull type — in this case both the South Bay 520CR 2012 and the South Bay 524SL 2013 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?
Size is the most obvious dividing line here. The South Bay 524SL 2013 measures 25,2 feet overall (2013), giving it roughly 3,4 additional feet of deck space compared to the South Bay 520CR 2012 at 21,8 feet (2012). At 173 lbs and 245 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.
The power gap is worth calling out. Rated to 150 hp, the South Bay 524SL 2013 has a 35-hp advantage over the South Bay 520CR 2012'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 524SL 2013 is rated for 13 passengers, while the South Bay 520CR 2012 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the South Bay 524SL 2013 could be the deciding factor.
Bottom line: Choose the South Bay 524SL 2013 if your priority is putting more people on the water — it handles 13 passengers and at 25,2 ft it has the deck room to back that rating up comfortably. The South Bay 520CR 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
