Dacron Sail Numbers & Letters – 230mm, 250mm, 300mm, 380mm & 450mm
These individual sail numbers and letters are supplied as separate digits or letters, so you can lay out your sail number correctly in line with your class rules and sail configuration. Choose your size, colour and number or letter above, and order the quantity you need.
Manufactured from durable, colour-fast sail number material, they are designed to withstand prolonged exposure to UV, salt water and repeated folding, making them ideal for club racing, open meetings and offshore use.
Ordering Numbers & Letters
Choose your size and colour, then pick the number or letter you need from the dropdown and add the quantity required. Add each character of your sail number to your basket in turn – for example, for GBR 1234 add one each of G, B, R, 1, 2, 3 and 4.
Choose Your Size
- 230mm – for dinghies where smaller identification characters are required, such as Optimist, Topper and Mirror.
- 250mm – a commonly used intermediate size, where 230mm numbers are too small and 300mm numbers are not required.
- 300mm – for adult racing dinghies such as the Laser / ILCA, Enterprise and GP14, and small keelboats.
- 380mm – for larger keelboats and yachts of roughly 8.5m to 11m. World Sailing's sail number rules set a minimum character height of 375mm for this length of boat, and 380mm is the closest size that meets it.
- 450mm – large-format characters for maximum visibility on boats over 11m, including larger keelboats, sportsboats, and handicap and club-racing yachts.
Colour Options
- Red
- Blue
- Black
Choose the colour that best contrasts with your sail for maximum legibility on the water.
Class Rules & Compliance
The World Sailing Racing Rules of Sailing require sail numbers to be clearly legible and of a contrasting colour to the sail. For World Sailing classes, Appendix G sets minimum character heights by overall boat length: 230mm under 3.5m, 300mm from 3.5m to 8.5m, 375mm from 8.5m to 11m, and 450mm over 11m. Other classes follow their own class or national authority rules, so always check your current class rules for exact sizing and placement requirements, particularly when racing at open or championship level.

Windsurfer to signwriter
It is always good to know that there is a reason behind why someone decides to go into a particular industry. My name is Sam Latham and I am the founder and owner of South East Signage, Signwriter Sussex.
Since the age of nine years old, I have been a windsurfer, pursuing a professional career in the sport and competing internationally for Team GB. I saw that there was a huge demand for eco-friendly sports signage to help competing athletes promote themselves and the brands that sponsor them – it was this that gave me the drive to produce great quality, durable Windsurfing Sail Numbers for competitive racing.
When I set up South East Signage, I decided that the first thing I needed to look at was how we produced Windsurf Sail Stickers. It then took me seven years to grow the environmental side of printing.
How it all started
I founded South East Signage during my degree placement year at Bournemouth Art University. During this time I studied 3D design, graphic design, wood and metalworking, digital printing and laser cutting which enables me to see a complete overview of a brand – this is especially valuable when a company is looking for a re-brand.
Passion and purpose – sail stickers that are kind to the environment
As a professional windsurfer, I am always respectful of the water and our planet. In the past Windsurf Sail Stickers would use PVC stickers made of materials that were harmful to the environment and difficult to recycle.
I wanted to change that. How could I windsurf, knowing that the stickers I had on my sail were no good for the environment? I am proud to say that our eco-friendly stickers are made from Polypropylene (PP) which is a highly sought-after material, however, only a few specific recyclers will recycle this.
If you are using PP stickers for a competition, please contact the sticker ambassador for Team GB who will return them to our company for recycling. This makes PP stickers far better for the planet – they will be recycled, whereas PVC will end up in landfill.
Sustainable signage for the future
The next step for our company is to continue looking at ways of producing, supplying, and shipping other products so they have minimal effect on the environment.
As a company, we produce stickers, banners and signs. As an environmentally-aware Signwriter, I am concerned about the environment. Our company continues to research eco-friendly ways of producing our products and disposing of waste. We have now found a recycling company that can recycle our normal PVC so that this has less impact on the environment, and we use water-based inks which are easier to dispose of than toxic equivalents.
We will continue to research and develop environmentally friendly materials for our customers – these may include biodegradable materials such as bamboo or hemp fabric. These materials are far less harmful to the environment and will break down over time. As soon as we have developed our next eco-friendly product, we will let our customers know and invite companies who are looking to reduce their carbon footprint to contact us.
Brand ambassadors
A large portion of our clients come from the water and extreme sports industry with personal passions in these sports – because of this, we like to give something back to the sports we love and support top athletes in the country. It is also a great way for us to test and develop products to ensure they are fit for purpose.
