My personal opinion:
You enter either as one up or two up, and sail the event that way. If you loose your crew you do the same as you do if you need/want to change crew/helm, you submit a written application to the jury. The jury can than either approve and make it know on the notice board, or they can deny the request. Fair enough for me.
Agreed.
You declare on entry if you are sailing 1 or 2 up;
If you break your crew, you need to find another one, and gain permission via the jury. You cannot add a crew (or remove) a crew during the event.
