All the sails used during an event must be declared. This applies also to the staysails tacked between the forestay and the mast and to all the sails that are smaller than the largest of their kind.
The sails that can be used during the event are only those listed in the fourth page of the certificate, regardless of the fact that other available sails are smaller than the largest of their kind listed on the certificate.
While it is not mandatory to carry all the declared sails while racing, the number of sails on board shall remain constant for each individual race day. The race day begins when the yacht leaves for the race course from its dock or mooring.
The minimum amount of liquids to carry onboard while racing is shown on the third page of the certificate as a fraction of one, under the sailing level column. The lowest number printed on the certificate is 0.100 also when the declared amount is zero.
It is mandatory to race with 1 headsail(s) always furled (see ORCSY rule 204.5)
It is permitted to unfurl the staysail to tack while furling the other headsail.
