I'm hoping to relocate my boat to a piece of property with a depth at low tide of about 3ft 10 inches. My draft is 3 ft 6 inches - winged keel. Bottom is sand/mud. Basic question is, assuming there are going to be times when she is sitting on the keel by a foot or so, is this going to cause any real "damage"? Appreciate any info. Bill "Salt & Pepper"
