First off apologies if this is a redundant topic for this thread. We just sailed our new (to us) 2000 Catalina 310 home yesterday. We had 2 days of 20+ knot winds and buried the port windows (that are located in the hull) all throughout the day. We noticed moisture around one of the windows, pulled the trim off and it was quite wet. Checked the other side and same thing. After reviewing many hours of YouTube videos, I'm still not sure of the fix for this particular window. I can see that the screws of the interior frame will disengage it from the frame on the outside. Do I then need to dig in under the exterior frame and release the sealant from the hull? If so, can I still use the same window and frame after cleaning everything up and resealing. It seems that marine grade silicone sealant is the proper material to use. Being that both windows are leaking, it seems as tho this may be a somewhat common issue for this model of window/boat. I could really use some back up here, as I am a total rookie regarding port window leaks.
