When two boats share the same hull type — in this case both the Allison XB-21 BasSport Pro Bass 2012 and the Allison XB-21 ProSport Bass 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?

On paper these two are close siblings in the size department — Allison XB-21 BasSport Pro Bass 2012 at 21,2 ft versus Allison XB-21 ProSport Bass 2012 at 21,2 ft. Weight tells a clearer story for trailering families: the Allison XB-21 BasSport Pro Bass 2012 tips the scales at 135 lbs — 122 lbs more than the Allison XB-21 ProSport Bass 2012 at 13 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 Allison XB-21 ProSport Bass 2012 tops out at 510 hp. Engine specs for the Allison XB-21 BasSport Pro Bass 2012 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 36 gal and 36 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 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.
