Leaking Port Window.

[Dmullen]

We were cruising last summer and had a couple days of heavy rain. We notice that water was coming above the portside sink and bed area. The above glass is leaking because the water is collecting on the lower left corner of the windshield and then dripping into the bed area, sink, etc. I will be getting the boat ready for the summer but concerned about leaking window. Any suggestions on what to do??
