The Graphite Vapor features a polyurethane core in the body of a Vapor. Polyurethane is damper foam which allows the ski to sit a little deeper in the water and makes for more progressive turns. Those skiing in a mix of open water and slalom courses favor the Graphite construction between speeds of 30-36 MPH.
