Saw the thread on foils and just thought i'd point out www.reverie.ltd.uk (click marine shop) make autoclaved pre-preg carbon foils finished in white durepox epoxy with clever internal carbon stringers running the full length, lighter and much stiffer than oem plus the trailing edge does not break out easily. Very happy with ours and we have an upf__cker bush fitted so we can pull the leward board up from windward on short course racing.
Avaliable for Nacra infusion (as used by several top teams) and new Hobbie wildcat (as used by Mischa at the worlds).
