When two boats share the same hull type — in this case both the South Bay 422FCR 2013 and the South Bay 620C 2008 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 422FCR 2013 measures 22,0 feet overall (2013), giving it roughly 20,0 additional feet of deck space compared to the South Bay 620C 2008 at 2,0 feet (2008). At 205 lbs and 195 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 — 90 hp for the South Bay 422FCR 2013 and 90 hp for the South Bay 620C 2008. 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.
For family outings this is probably the sharpest distinction between the two. The South Bay 620C 2008 is rated for 11 passengers, while the South Bay 422FCR 2013 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the South Bay 620C 2008 could be the deciding factor.
Bottom line: Choose the South Bay 620C 2008 if your priority is putting more people on the water — it handles 11 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The South Bay 422FCR 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
