The Pro-Line 20 Bay 2006 vs Pro-Line 23 cc 2011 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.
Size is the most obvious dividing line here. The Pro-Line 23 cc 2011 measures 23,0 feet overall (2011), giving it roughly 21,0 additional feet of deck space compared to the Pro-Line 20 Bay 2006 at 2,0 feet (2006). At 22 lbs and 32 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 200 hp for the Pro-Line 20 Bay 2006 and 200 hp for the Pro-Line 23 cc 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 — 6 gal and 7 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Pro-Line 23 cc 2011 is rated for 7 passengers, while the Pro-Line 20 Bay 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pro-Line 23 cc 2011 could be the deciding factor.
Bottom line: Choose the Pro-Line 23 cc 2011 if your priority is putting more people on the water — it handles 7 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Pro-Line 20 Bay 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
