When two boats share the same hull type — in this case both the South Bay 722F 2008 and the South Bay 925SL 2009 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 South Bay 722F 2008 carries a rated maximum of 115 hp. Engine data for the South Bay 925SL 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the South Bay 925SL 2009 carries 51 gallons versus 18 gallons in the South Bay 722F 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The South Bay 722F 2008 is rated for up to 12 people. Passenger data for the South Bay 925SL 2009 wasn't available.

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.
