Matching a flat Weld-Craft Cajun 2012 against a deep vee Weldcraft Marine 18 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

The Weldcraft Marine 18 2011 measures 18,1 feet overall (2011), giving it roughly 5,1 additional feet of deck space compared to the Weld-Craft Cajun 2012 at 13,0 feet (2012). Weight tells a clearer story for trailering families: the Weld-Craft Cajun 2012 tips the scales at 225 lbs — 201 lbs more than the Weldcraft Marine 18 2011 at 24 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.
The Weld-Craft Cajun 2012 carries a rated maximum of 25 hp. Engine data for the Weldcraft Marine 18 2011 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.
