The Pro-Line 20 cc 2011 vs Pro-Line 21 Sport 2006 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.

On paper these two are close siblings in the size department — Pro-Line 20 cc 2011 at 20,5 ft versus Pro-Line 21 Sport 2006 at 21,0 ft. Weight tells a clearer story for trailering families: the Pro-Line 20 cc 2011 tips the scales at 2 115 lbs — 2 089 lbs more than the Pro-Line 21 Sport 2006 at 26 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 200 hp, the Pro-Line 21 Sport 2006 has a 50-hp advantage over the Pro-Line 20 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 — 7 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.
