Both the Jetcraft 1875 Whitewater J-MAX 2009 and the Jetcraft 2175 Extreme Shallow 2011 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?
