We have written in another website article where to source computer cut vinyl hull numbers. (I used “Vinyl Letters Ltd”).

There’s a trick to putting them on. See below.

For the IOM, and I think all the international classes, the minimum height allowed is 20mm. The numbers arrive on a strip about 25mmx80mm, nicely spaced and so on – which for our application is irrelevant. They were only about £2.50 a strip, so I ordered two strips, assuming I would wreck at least one number.

Honestly, I didn’t think the four digits would fit around the curve. I cut the strip into individual numbers and worked it that way.

Now you know the “hack”, do you?? Wet the surface first, before applying the letters, with a mild soapy solution – water and dishwashing liquid. You don’t want neat fairy liquid, but when you smear it on the surface if to the naked eye it runs off, then it’s too weak. Add a few more drops of soap to the mix and try again. Eventually your smear will stay on the surface.

Then one character at a time, sticky side down, you’ll find you can attach them and slide them around to get them in the desired place. Then just leave them to dry out. Hopefully you’ll find them 100% stuck on.
