looks like a tarp is in order!
I am lucky in that I have a full cockpit enclosure, so no water can get in through much of that area. I'm sure that I would be in your situation otherwise. Windows - I have had window leak problems too. That's when I bought the Butyl tape (tape available through RV stores to seal RV windows - identical to plumbers putty but formed into a long even strip). The screws come out, you pop out the window (push evenly - it will pop out - have someone on the outside to catch it), clean up the old caulking on the cabin and window frame, apply butyl tape around the window frame, and stick it back in and replace the screws. If they leak from between the glass and the frame then you need the full fix which is very time consuming and difficult.Stanchions - they are what support the lifelines - most of mine have leaked. Use 3M 4200 caulking on them.I have come to the conclusion that the drip problem will never be completely solved. There are just too many places for water to get in. I have to admit that the big tarp over the windows midships area has helped me save my sanity - although I think I have solved my drip problems...for now.If you look on my website you can see the window leak fix.Good luck!-Rob
