The Pro-Line 21 Sport 2007 vs Pro-Line 22 Bay 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 21 Sport 2007 at 21,0 ft versus Pro-Line 22 Bay 2006 at 21,0 ft. At 26 lbs and 25 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 225 hp, the Pro-Line 22 Bay 2006 has a 25-hp advantage over the Pro-Line 21 Sport 2007's 200-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 6 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.
