Because of the relative shallow angle of the Vs, a standard 8 foot rack will accommodate a multitude of hulls from a razor sharp Vandusen Eagle, to an Epic V8 ski. The wider boats simply sit a little higher in the Vs. There are very few performance boats that won’t fit well onto it. The PAX 20 is one. It is wide, but more importantly it is long and wide. For this boat and similar, I try to keep extra Vs that have a more flattened angle to them. Most sea kayaks in the 17-18 foot range fit fine since they are shorter, and the hull is more narrowed toward the contact points. It is a great rack for just about any long item. I use mine for lumber, tubing, ladders, and of course, I use mine to haul your boxed up racks to the shipper.
