INTRODUCTION
The RS:X is a sailboard developed by Neil Pryde Ltd.
RS:X hulls, hull appendages, rigs and sails shall only be manufactured by Neil Pryde
Ltd or their appointed manufacturers. Such equipment is required to comply with the
RS:X construction manual and is subject to an ISAF approved manufacturing control
system.

whatever inspection methods they deem appropriate, including comparison
with a standard or a sample of other equipment presented for Inspection.
Should this comparison reveal deviation greater than the Equipment
Inspector considers to be within manufacturing tolerances, this should be
reported to technical representatives of ISAF, IRSXCA and NPL for
investigation and a decision on the legality of the equipment. If this
investigation takes longer than the time available for inspection, the owner
may present alternative equipment for Inspection.
