Crew weight. For resons explained at length, we use the average height and weight, I think from the WHO via the ISAF technical Director.

F16 sailor (Nope; from about 65kg to around 110!!); Ditto A class; F18; tornado etc... Non starter

The person with the gripe on the measuring break ws told to get his boat measured; not our problem if that does not happen. Move on.

SCHRS and TEXEL measure some items slightly differently; TEXEL reps and Members of the SCHRS managment group are discussing this and there MAY be some combining / sharing of measuring methods.
