Bic One Design
BIC Windsurf developed the One Design Rig package for use specifically by youth sailors on hybrid boards. This rig package has been designed to be raced in the widest wind range possible, representing the best possible compromise between light wind pumping performance and high wind planing performance.
A huge wind range: from 6 to 30 knots. By tuning the downhaul and outhaul, the sail can be rigged either very full with a tight leech, or very flat with an open leech.
