We have had 40-60 beach cats on our beach in South Florida for the last 20 plus years, from 14-21 feet. NOT ONE HAS EVER BEEN REGISTERED. This topic comes up from time to time and the only sailors who ever have a problem are the ones from Dunedin. I am on beaches on the East coast of Florida from the Keys to Melborne and never see one register .
Just to clarify, We in Dunedin have not had any problems with it. There was one guy in St.Pete that had a Dart 20 who was trying to sell it to someone out of state. That person needed a title so they could register it in their state. It became a can of worms trying to get a title since Darts don't have VIN #'s. Instead of selling it he wound up cutting it into little pieces and throwing it away.
