I read it as you state the main ,jib & kite at the start of the regatta.. Unless there is an issue these are the sails one uses.. The intent originally was so we don't see the vast wardrobes of sails starting to appear.. Like the skiffs where up to 5 complete sets of sails & masts are found on every boat..

I have no issue personally, with someone deciding to only take the jib & kite out.. Even as a solo..
The only issue is weight.. But as long as the weight is still over the class limit .. who cares?
