Change(s) at LaserPerformance USA

"Formerly known as Vanguard, LaserPerformance makes sailboat types such as the Laser, Optimist, 420 and Sunfish, and is in the process of transitioning the method for making their hulls from an open-mold system to an “infusion,” closed-mold system similar to how the foils are made."
Ah, good old one -design! Anyone have experience of closed-molded boats?
