I have a circa 1923 Dan Kidney and Sons (Fox River Boatworks) 16' foot square stern two-man pleasure rowboat (confirmed through photos and nameplate by the Depere Maritime Museum). My father passed away and left the boat to me. It has been in storage for many years. I recaulked the keel two years ago, per my father's instructions, and used it for the following summer but I was told it would need to be recaulked every year. It was a painstaking process and I wondered should I use a different caulking? Is there any easier way to do it?
