The 24-year-old teak decks were showing signs that water was getting through to some parts of the Plywood base. We knew when we bought Blue Heron that we would have to deal with this issue.
The Teak was removed by Sawing across the planks then chiseling it off in small chunks.
The winches were too far outboard.
I was never comfortable relying on a bit of canvas to prevent water getting below through the hole in the cockpit required for the tiller to attach to the rudder stock.
