When two boats share the same hull type — in this case both the South Bay 722CLR TT I/O 2010 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 722CLR TT I/O 2010 carries a rated maximum of 300 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 31 gallons in the South Bay 722CLR TT I/O 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The South Bay 722CLR TT I/O 2010 is rated for up to 13 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.
