The Blazer Boats Bay 2170 2005 vs Blazer Boats Bay 2220 Pro 2005 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 — Blazer Boats Bay 2170 2005 at 21,0 ft versus Blazer Boats Bay 2220 Pro 2005 at 22,0 ft. Weight tells a clearer story for trailering families: the Blazer Boats Bay 2170 2005 tips the scales at 1 359 lbs — 1 194 lbs more than the Blazer Boats Bay 2220 Pro 2005 at 165 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 300 hp, the Blazer Boats Bay 2220 Pro 2005 has a 100-hp advantage over the Blazer Boats Bay 2170 2005'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 — 5 gal and 6 gal — so range won't be a tiebreaker here.
Both boats are rated for 8 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: Performance buyers should lean toward the Blazer Boats Bay 2220 Pro 2005 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Blazer Boats Bay 2170 2005 with its 200-hp rating is the more economical daily driver.
