The South Bay 529CR Upper Deck 2011 vs South Bay 930CR 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Both boats share a closely matched power ceiling — 150 hp for the South Bay 529CR Upper Deck 2011 and 150 hp for the South Bay 930CR 2007. 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 29 gal — so range won't be a tiebreaker here.
The South Bay 930CR 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The South Bay 529CR Upper Deck 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The South Bay 529CR Upper Deck 2011 and South Bay 930CR 2007 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.
