My cups and plates slide around at sea, I have some non skid material to put on counter tops but it is a pain to clean. I saw some cheap boat plastic plates with a bead of some non skid clear on the bottom. It seems to me a better solution to apply a similar bead to my corelle and mugs to keep them put. Any of you folks tryed something similar? Hopefully with good results? Tom Evans. Cat Harbor Catilina Island
