INSIGNIA DACRON ADHESIVE SAIL NUMBERS

What Size SAIL Numbers Should you purchase

We are often asked “what size sail numbers do I need for my boat” The answer is, thankfully, quite simple and regulated by World Sailing (was the ISAF) under rule G1.2 (ref1). If you are looking to BUY some of our adhesive Sail Numbers – please click the links below to visit our eBay Store. The size of the Sail Number is determined by the boat’s overall length. The table below summarises this rule :

3.5m to 8.5m300mm60mm
8.5m to 11m380mm75mm

Easy to Apply Insignia Dacron Sail Numbers

We stock and sell various styles of Adhesive Dacron Sail Numbers. The most popular numbers are supplied in a form known as “DIGITAL 8“. In the same way an old LED display works – the sticker is CUT to produce the desired numeral. All digits from 0 to 9 can be formed by simply snipping the unwanted segments away. The diagrams below show the two styles of Sail Number available from SailStickers.co.uk. We have TWO styles of Digital 8 stickers – Style 1 has a visible GUIDE around the side showing where to cut – Style 2 does NOT.

Do all Classes Support Digital 8 Numbers?

Unfortunately NOT. Certain classes such as the 29’er do NOT allow the application of the DIGITAL 8 numbers. If in any doubt – please consult with your Class Association to check the rules.

Some Examples of these sail numbers

The first image shows a Laser 1 – ILCA7 with the DIGITAL 8 numbers personalised for the specific Laser Sail Number. If you look carefully – the cut guides can be seen around the outside edge. These guidelines make it easier to cut each number accurately and cleanly. The second image shows the other format of DIGITAL 8 numbers – those WITHOUT the guidelines.
