How to Replace Sail Numbers & Insignia

Item # X-HT-300074

Have your sail numbers or insignia seen better days? Old sail numbers and insignia were made of vinyl that would dry out and crack in the sun. If your numbers or insignia are cracked or faded, or if you have a new-to-you sail with someone else’s numbers, then you’ll want to replace them. It’s not hard to do, but it does take a little patience. Let’s take a look at removal and installation of sail numbers.

Replace old sail numbers or insignia with fresh designs.

Before you remove the numbers or insignia, you’ll want to buy or pattern your replacements. For numerals, you can purchase pre-cut numbers or a Computer Eight, which you can cut into any number 0-9.

To replace the insignia, you’ll want to use a clear patterning material, like Dura Skrim®, to trace the shape of your existing insignia. Cut out the shape and use this pattern to trace your logo on to Adhesive-backed Insignia Dacron® and cut it out with scissors. Be sure when you do this that your shape will face the correct direction when applied to the sail. To see a demonstration of patterning insignia, watch our how-to Make a Sail Logo Video (200163XHT).

Removing the Old Numbers

    How to remove old sail numbers or insignia
  • Peel off the old numbers.
  • To remove the sticky residue, use 3M™ Adhesive Cleaner. Apply solvent to a soft cloth and rub over the adhesive until the solution can soak in. Leave the sail for a bit while the solvent soaks in.
  • Using a terry cloth or other soft towel, scrub off the glue residue.

Adding New Numbers

How to install numbers or insignia on a sail

When adding your new numbers or insignia, be sure to refer to class rules on where to position the markers on your sail.

  • Allow the sail to dry out.
  • Starting at a short edge, peel back a small section of the backing paper. Stick the corner in the desired location on the sail and smooth it out, making sure there are no air bubbles.
  • Working slowly, continue to peel small portions of the paper off and smooth out the Dacron. Take care on numbers with a hole, to not stretch the Dacron material as you apply it.
  • When you are satisfied with your placement, allow the adhesive to cure for 24 hours. After this time, the glue will be permanent.
