When two boats share the same hull type — in this case both the South Bay 524CR 2013 and the South Bay 820CR TT 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?
Size is the most obvious dividing line here. The South Bay 524CR 2013 measures 25,2 feet overall (2013), giving it roughly 3,2 additional feet of deck space compared to the South Bay 820CR TT 2009 at 22,0 feet (2009). Weight tells a clearer story for trailering families: the South Bay 524CR 2013 tips the scales at 247 lbs — 225 lbs more than the South Bay 820CR TT 2009 at 22 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 175 hp, the South Bay 820CR TT 2009 has a 25-hp advantage over the South Bay 524CR 2013's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 13 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The South Bay 524CR 2013 at 25,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The South Bay 820CR TT 2009 at 22,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
