NALSA SAIL NUMBER Purchase and Installation Notes


NALSA has sail numbers, U.S. and Numbers for sale. These are black, laser-cut, 10 in size, with rounded corners. Beautiful works of art and readable by the race committee. These letters and numbers will definitely allow you to sail faster and make you proud. Allegedly, you will be in the winner’s circle frequently if you have these figures on your sails. So, order up an ample supply to satisfy your appetite for that beautiful fresh and fast appearance. Old worn out sail numbers will only slow you down. Order today for $3.00 each plus $2.50 shipping (per order).

Installation: Place letters and numbers on the top 1/3 of the sail. Race committee members will be looking for them there. Place the starboard (right side) letters and numbers above the port (left side). NEVER, NEVER PLACE BOTH SIDES BACK TO BACK ON FABRIC or TRANSPARENT SAILS. Light conditions and dust will make reading your number impossible. The exception is a solid wing, here you can place them on opposite sides of the sail at the same level if desired as they cannot be seen through the wing. It is preferable to place the country code (ie: US) on a separate panel above the number for easier reading.

From the NALSA Rules:

• Numbers should be10 inch minimum,

• Bold, San Serif font (Helvetica Bold for example) not slanted.

• In a color that contrasts strongly with the sail color.

Note: Sail numbers do not automatically transfer when a landsailer is sold. They are assigned to the pilot, not the boat. The owner must contact  or fill out and mail in one of the linked forms to transfer the number.

Examples of correct placement: US above the number is the preferred configuration, highly recommended for all new sails or number changes.
