the boat in accordance with the following procedures:

placed on a solid background that contrasts strongly with the color used for the deck numbers.
3. The numbers must be so displayed as to be clearly visible at all times, and shall be securely attached in such a manner that they will not be lost
or defaced during a race. The race committee shall have the power to warn, or disqualify without previous notice, any driver who races with improper
or illegible numbers.

responsibility to affix a temporary identifying mark to his/her second entry to assist the scorers in identifying the drivers. The identifying mark shall be
in the form of the letter “I” following the official racing number. If the owner enters three boats in the same race, the third entry shall have two such
identifying marks following the official racing number, and so forth. Such temporary marks are for the use of the local headquarters or race committee
and have no official standing at National Headquarters.

RULE 22 • BOAT NUMBERS 1. Owners are to fasten their assigned numbers to each side of the boat in such a manner that the number is readily visible to the officials. Numbers must remain intact throughout the race. Failure of the number to be visible may disqualify the boat. Black numerals on a white background that is approximately elliptical or rectangular in shape, or the reverse of the preceding, is acceptable. Vertical block characters shall be used and be a minimum of twelve inches (12”) high and a minimum stroke of two inches (2”). Less than 12” minimum is acceptable only if the surface area will not allow otherwise, and the numbers must be as close as possible to the stated minimum standards. Should the background be the same color as the adjacent section of the boat, a 1/2” contrasting, approximately elliptical or rectangular, border is required. Spacing between numbers, and between borders and numbers, must be at least two inches (2”). Numbers, as well as the background and borders may not be angled or tilted. The National Office assigned number must take precedence in case of a number conflict. The legality of any boat numbering is the responsibility of the Race Committee only and cannot be protested.
