When two boats share the same hull type — in this case both the Blazer Boats 2220 Professional 2008 and the Blazer Boats 675 Ultimate Bay (2013) 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?

The power gap is worth calling out. Rated to 250 hp, the Blazer Boats 675 Ultimate Bay (2013) 2012 has a 100-hp advantage over the Blazer Boats 2220 Professional 2008's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Blazer Boats 2220 Professional 2008 is rated for 8 passengers, while the Blazer Boats 675 Ultimate Bay (2013) 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Blazer Boats 2220 Professional 2008 could be the deciding factor.
