Matching a modified vee Blazer Boats 2020 2009 against a deep vee Blazer Boats 2170 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Blazer Boats 2170 2012 measures 21,6 feet overall (2012), giving it roughly 19,6 additional feet of deck space compared to the Blazer Boats 2020 2009 at 2,0 feet (2009). At 155 lbs and 145 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 140 hp, the Blazer Boats 2170 2012 has a 25-hp advantage over the Blazer Boats 2020 2009's 115-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 5 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: The Blazer Boats 2170 2012 at 21,6 ft is the right call if deck space, comfort, and entertaining are top of your list. The Blazer Boats 2020 2009 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.
