Laser Sails and Numbers

The most important Laser rules to get right before you go to a regatta are to do with your sail. Why? Because sail numbers are a time-wasting pain to put on, and an even bigger pain to take off or replace. And if you try to do it at the last minute, they won't stay stuck on.

Why do we place such importance on sail numbers?

The Race Committee (and the Jury) needs to identify your boat through your sail number:

• if you're over the Start Line
• when you cross the Finish line
• if you are seen to infringe a Racing Rule
• if you need to be identified for safety reasons

What to do:

Remember the six Ps! Make sure you have checked these sail-related items before you pack your sail ready for the weekend. It's a real pain having to put new sail numbers on with only two hours before the first start of a 'Q' event.

You will not be allowed to enter a 'Q' event or the Nationals with an incomplete or incorrect sail-number.

Sail rules to remember

• The sail-number must match the boat number. Dispensation will only be given if you've borrowed or chartered a boat. There is no excuse for not having the right numbers for your own boat.
• Contrasting numbers for any sails bought since 1/6/1993, regardless of the boat's age. The last four numbers must be of a different and contrasting colour from the preceding numbers. The following colour-combinations are acceptable:
  • Red and black (recommended) e.g: 183456, 75345, 4567
  • Red and Royal blue e.g: 183456, 75345, 4567
  • Royal Blue and black e.g: 183456, 75345, 4567
  Other colour combinations such as green/blue may be refused as being insufficiently contrasting. Just don't even think about yellow numbers!
• Complete sail numbers: please don't try to be clever and come with 183 and think you'll be allowed to race. Bit dumb to do this anyway; apart from a blank sail I can't think what stands out more on the start line than a 3-digit sail-number.
• The gap between each number is recommended to be 60mm (40mm for the 4.7). I know the gap can be a narrow as 50mm (30mm for the 4.7), but I would leave at least 55mm (35mm for the 4.7) for safety, and even then only if I were experienced at sticking numbers on. Getting this wrong can get expensive if the error means several digits have to be moved. For a few millimeteres off the length of the sail-number it's really not worth it.
• Size of numbers must be appropriate to the rig: 4.7 numbers are smaller (220mm x 150mm)
• Position on the sail must be correct, starbard-side numbers uppermost, and the distance from the leech must be at least 100mm±12mm for each number/letter set.
