We'll see if it works
Just came across this thread. I had been wondering where the water in the cabin was coming from when all of a sudden it started to rain yesterday morning. All of a sudden I felt it dripping on my neck as I worked on the radio. Same problem that others have described, water seeping in under the plexiglass hatch. The three screws that hold the teak runner were a little loose, but tightening them didn't solve the leak. I ran out to the boat after work today and laid down a bead of silicone along the length of the runner, extra at the screw holes, and screwed it on real tight. I'll let you know how it turns out after the next rain.
