Hello Derrick
Location of numbers seems to vary. The hull numbers and sail numbers don’t necessarily match up.
My Dinky (non-sailng) has its hull number 446 punched into the top surface of the hog – inside the boat – about a foot forward of the transom.
My Ducking has its hull number 1061 punched into the transom on the inside of the boat and you have to be something of a contorsionist to see it as it’s ‘hidden’ beneath the aft thwart. The sail number, rather optimistically, is D1. Nothing to do with Atalanta being A1 – merely tha sails when I got the boat.
So I would just pick a sail number of your choice and make sure the duckling logo is prominent on the sail (Mine isn’t)
Good hunting!
Mike
