Hello S2 owners;Please be kind to this poor Catalina owner;-))I help my boat storage and hauling facility launch sailboats in our area.Last year when hauling out a 11m S2, the mast was very difficult to remove. The previous facility had used 3M 5200 to caulk the mast to the deck! There was some damage to the red rubber "doughnut" that cushions the mast at the deck pass through.Is there a source for the red rubber donut (or what ever it is called) that is in the deck pass through for this boat?I have recommended to the owner to use a universal mast boot to help waterproof the pass through. Any suggestions?Thanks in advance for your help.Fair windsDave
