The Blazer Boats 210 Pro-V 2010 vs Blazer Boats Bay 2170 2007 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 210 Pro-V 2010 at 21,0 ft versus Blazer Boats Bay 2170 2007 at 21,0 ft. Weight tells a clearer story for trailering families: the Blazer Boats Bay 2170 2007 tips the scales at 1 359 lbs — 1 214 lbs less than the Blazer Boats 210 Pro-V 2010 at 145 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 Blazer Boats 210 Pro-V 2010 has a 85-hp advantage over the Blazer Boats Bay 2170 2007's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Blazer Boats 210 Pro-V 2010 carries 24 gallons versus 5 gallons in the Blazer Boats Bay 2170 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Blazer Boats Bay 2170 2007 could be the deciding factor.
Bottom line: Choose the Blazer Boats Bay 2170 2007 if your priority is putting more people on the water — it handles 8 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Blazer Boats 210 Pro-V 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
