When two boats share the same hull type — in this case both the South Bay 520CR TT 2009 and the South Bay 522FCR 2011 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?
On paper these two are close siblings in the size department — South Bay 520CR TT 2009 at 21,0 ft versus South Bay 522FCR 2011 at 23,6 ft. Weight tells a clearer story for trailering families: the South Bay 520CR TT 2009 tips the scales at 186 lbs — 168 lbs more than the South Bay 522FCR 2011 at 18 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 520CR TT 2009 has a 25-hp advantage over the South Bay 522FCR 2011's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 31 gal and 31 gal — so range won't be a tiebreaker here.
Both boats are rated for 12 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.
Both are 3-tube and 2-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
Bottom line: The South Bay 522FCR 2011 at 23,6 ft is the right call if deck space, comfort, and entertaining are top of your list. The South Bay 520CR TT 2009 at 21,0 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.
