Some feedback on our stickers:
The boat name (Shantaram) was 891mm x 100mm, and the port name (Jersey) was 675mm x 100mm. The font was sans serif.
We were obligated to have a minimum height of 10cm for the letters as per Jersey registration
The small down-light in the centre of the transom step made positioning a bit of a challenge....as if trying to get a vinyl sticker on straight wasn't bad enough.
All completed successfully in the end though.
Thanks everyone for the assistance.
