Last night was a heck of a night. I was up all night last night because of the weather that moved through the ancorage in Deltaville (I am in Jackson Creek). The wind was crazy. I found that one of my lexan windows was leaking, like a running faucet, and a cushion in my salon got really wet. That window had never leaked before (not at all). I am thinking that when I beat to windward in rough seas the other day it may have knocked some things loose. I went outside, in the rain, and checked the screws that hold the window to the frame. All of the top screws were loose. I tightened them and I noticed that one particular screw is starting to strip. My question is for anyone with a Catalina, around the early 90's vintage, that has taken the lexan windows out and re-sealed them. How hard of a job is this? What calking material did you use? Did you have any screws that had stripped and if so how did you fix that problem?Thank you in advance for any further information that you can provide me.Just a side note to this story, I discovered that I was aground at 4 in the morning. I waited until it got light and I was able to take the ancor rode and my primary winch and get off of the bar. It was a lot of fun re-setting the hook in 25 knot winds. What a mess and what a night!
