When two boats share the same hull type — in this case both the Blazer Boats 180 Pro-V 2009 and the Blazer Boats 2020 2011 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?

On paper these two are close siblings in the size department — Blazer Boats 180 Pro-V 2009 at 18,0 ft versus Blazer Boats 2020 2011 at 20,2 ft. Weight tells a clearer story for trailering families: the Blazer Boats 2020 2011 tips the scales at 155 lbs — 144 lbs less than the Blazer Boats 180 Pro-V 2009 at 11 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.

Both boats share a closely matched power ceiling — 115 hp for the Blazer Boats 180 Pro-V 2009 and 115 hp for the Blazer Boats 2020 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Blazer Boats 180 Pro-V 2009 carries 18 gallons versus 5 gallons in the Blazer Boats 2020 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Blazer Boats 2020 2011 is rated for 8 passengers, while the Blazer Boats 180 Pro-V 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Blazer Boats 2020 2011 could be the deciding factor.
