Berkshire’s 25 Sport RFX9 is a quick-performing pontoon boat with the Mercury Verado 300; we dropped the throttle handle and had it planing at 14 mph in just 3.75 seconds, and we hit 30 from a dead idle in just 6.9 seconds. Ours was a 50 mph performer, and we achieved our most economical cruise at 3,500 rpm, 22.5 mph and 7.7 mpg. At that speed, the 52-gallon tank (mounted in the center tube) yields a range of just over 118 miles, with a 10 percent reserve. That’s solid performance from a boat that’s competitively priced. Below deck, three 25-inch diameter tubes with four stepped lifting strakes and two outside spray rails give the Sport RFX9 3.0+ a sturdy ride at cruising speeds without sacrificing comfort or rough-water capability.
