Just an FYI, I put on 24cm tall vinyl numbers on my boat to meet the rules on the weekend and yesterday had the boat in the water for 26 miles of running. They held up fine. the extream heat made one corner lift a little but they held on no problem overall. A simple an inexpensive way to meet the rules and easily remove after the races rather than painting your boat.
As mentioned in a post before... I will provide free race numbers to first time racers at Dunnville for your ThunderCat in black or white (which ever suits your boat colour) to help offset the costs of a first race. It's a small thing, but it's something. You need to let me know a week in advance so I have time to get them made.
