I own a 16 foot marine plywood sailing dory. I have tried to fix the
leaks on the seams of the boat with Life Caulk but after a season or
two I am back to bailing as much as I am sailing. Are there any other
inexpensive do it yourself options for my boat? The boat is on a
trailer so she is easy to work on. Any suggestions would be
appreciated. Thanks!
