is there any way to tell the age of a AA Broadbill based on the Serial Number? I just picked one up and I know most of the owner history but dont have a timeline. It seems to be in good condition for an old boat (ie have not found any soft spots). Just REALLY dirty and the gelcoat is oxidized and covered in tree sap. Thinking it will get hunted this season then do a "restoration" on it next summer.
