Hello all this is my first post on this forum. A question has arose on the number of my sailboat. Backstory: About a month ago I purchased a Laser that was made in 2012 from what the owner said, and he had only sailed it for a few times so it was essentially new. I've always sailed radial, but recently I have reached the substantial weight to support a standard sail. I received one training sail (intensity sails), and two race sails. None of the sails had numbers on them so I purchased numbers. I was getting the serial code from the stern of the boat. I had the serial of: US-OQTL3124H122. I then went to the laser xd site to see what my sail number was with the given serial code. I had the sail number: 213124 I then thought to myself that this number couldn't be correct, because I have never seen a sail number that had a 21 as the frist two numbers. I then went to the Laser website to find out if a sail number with the first two digits above 21 existed. It didn't. So I then went back to the Laser xd website to see if I did something wrong. It says that A=10 B=11 C=12 D=13 E=14 F=15 G=16 H=17 I=18 J=19 so I assumed K=20 L=21. And there is the L in my serial code, which symbolizes the first two digits of the number. I'm in a pickle, and don't know what to do. Could anyone help me out? Thanks, Duke
