Yes, here on Eolian, with the first rain we had drips coming in around the mast. I never cease to be amazed at how much water can find its way inside thru a tiny, tiny hole. In this case, the leak was a tiny place on the back of the mast boot, at the bottom of the seam on the back. I had closed the seam with 3M 5200, but the last 1/8" of that closure had opened up, slightly. One eighth of an inch. And yet I had to put a container on the floor to catch the water that came in there.
In the ever timeless scenario, it was not possible to work on stopping the leak while it was raining... so I had to wait until it stopped. Thankfully it was easy to find the problem. A small dab of 5200 fixed the problem - today's rain proved it.
