Just bought a 1985 Wellcraft 192 American. Second time out on Lake Erie I ran into some pretty rough water. Discovered i have a leak about three feet back from the bow. its right where the rub rail is. it appears there might be a seperation, maybe 6 or 8" long. Can't really see anything from the inside without removing the carpeting in the cuddy. all i know is everything got soaking wet in the cuddy and water ran from the bow to the stern. not alot, but enough to get everything wet. the rub rail appears to be chalked on the bottom around the entire boat. can i just rechalk it? it is seperated maybe 1/8" where the leak is. what kind of sealant would be best? Thanks for any help.
