A boat breaks rule 18.3 at the finish line when she causes a boat who has been on starboard tack since entering the zone to sail above close hauled to avoid contact.

Pumping out bilge water for the purpose of changing a boat’s trim or stability does not break rule 51, however, class rules may limit the amount of bilge water allowed and/or put restrictions on the time and/or the type of bilge pump used to bail water out.
