The seven years of development required to perfect the XB-21 bass boat hull is a prime example of the tenacity devoted to perfecting fishing boat performance and efficiency at Allison Boats. The XB-21 ProSport bass boat provides the same distinguishing excitement from top-end speed and superior rough water handling as all other Allison Boats have before. After tirelessly testing and re-designing to attain easy handling, superior rough water capability, unequaled load carrying ability, and blistering top-end speeds, there was still one test that was not up to standard. The hole shot. A whole new regimen of testing was required. Two years later with a brand new patented design, the XB-21 bass boat had a better hole shot than any other 21′ class boat.

“You can have it all”
“…XB-21 is one of the best-riding and fastest bass boats we have run. Seven years in development, its layout is loaded with innovations . . . . . the console design is so refined you can carry on a conversation in a normal voice while running at speed. Even in a nasty chop, the ride is exceedingly smooth . . . , and a Mercury 200 XS can push the hull beyond 82 mph. For speed and comfort, few boats can hold a candle to the Alli— our pick for the most unique and effective new boat design in the past 10 years.”
