When I bought my boat it wasn't named, at least it isn't painted on her anyway so Gilly Mac it became. I am looking to buy a larger boat in the near future and as I plan on buying a used boat it will more likely then not be named. I have always been told that it is bad luck to rename a boat that is already sporting a name. Is there an appropriate method or tradition on how to rename your boat? By the way, I am never opposed to a tradition that calls for single malt scotch.
