When two boats share the same hull type — in this case both the Blazer Boats 2020 2008 and the Blazer Boats 2420 Professional 2012 are modified vee designs with composite construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Blazer Boats 2420 Professional 2012 measures 24,2 feet overall (2012), giving it roughly 22,2 additional feet of deck space compared to the Blazer Boats 2020 2008 at 2,0 feet (2008). At 165 lbs and 195 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 200 hp, the Blazer Boats 2420 Professional 2012 has a 85-hp advantage over the Blazer Boats 2020 2008'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 8 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 2420 Professional 2012 at 24,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The Blazer Boats 2020 2008 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.
