Both the Fish-Rite Rivermaster 19 ft. (91 in. beam) 2007 and the Fish-Rite Stalker Open Series 2009 are modified-V designs, both built in aluminium, so 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?

(91 in. beam) 2007 tips the scales at 1 100 lbs - 350 lbs more than the Fish-Rite Stalker Open Series 2009 at 750 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.
