controlled by the ILCA Technical Officer. Therefore each Laser sailor can be sure when he participates at a regatta that the other sailors have no technical advantage over him because everybody has the quasi identical equipment. However, this system is costly. The tight tolerances lead to rejects in manufacturing. Inspection costs are higher. Copy parts are not controlled and can therefore be produced at lower cost From December Laser World. Tight tolerances lead to reject in manufacturing... Somehow I do not belive that to be the main reason for the higher cost.
