When two boats share the same hull type — in this case both the South Bay 525CPTR TT 2011 and the South Bay 529CR Upper Deck TT 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?
Both boats share a closely matched power ceiling — 225 hp for the South Bay 525CPTR TT 2011 and 225 hp for the South Bay 529CR Upper Deck TT 2011. 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. Both carry nearly identical fuel loads — 31 gal and 31 gal — so range won't be a tiebreaker here.
The South Bay 525CPTR TT 2011 is rated for up to 17 people. Passenger data for the South Bay 529CR Upper Deck TT 2011 wasn't available.
One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 25" diameter. That shared spec means stability and buoyancy characteristics are closely matched — the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
Bottom line: The South Bay 525CPTR TT 2011 and South Bay 529CR Upper Deck TT 2011 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
