The Pro-Line 20 Bay 2006 vs Pro-Line 21 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 21 cc 2011 measures 21,7 feet overall (2011), giving it roughly 19,7 additional feet of deck space compared to the Pro-Line 20 Bay 2006 at 2,0 feet (2006). At 22 lbs and 27 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.
The power gap is worth calling out. Rated to 200 hp, the Pro-Line 20 Bay 2006 has a 50-hp advantage over the Pro-Line 21 cc 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 — 6 gal and 7 gal — so range won't be a tiebreaker here.
Both boats are rated for 6 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 Pro-Line 21 cc 2011 at 21,7 ft is the right call if deck space, comfort, and entertaining are top of your list. The Pro-Line 20 Bay 2006 at 2,0 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.
