Both the Fish-Rite Kenai Series 2009 and the Fish-Rite River Barge 18 ft. 2007 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?
On paper these two are close siblings in the size department - Fish-Rite Kenai Series 2009 at 20,0 ft versus Fish-Rite River Barge 18 ft. 2007 at 18,0 ft.

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.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fish-Rite River Barge 18 ft. 2007 could be the deciding factor.
