I am the owner of a Bertram 58 Motor Yacht with a 10ft added cockpit. I am having problems solving leaks in the salon area from what I thougth was the windows. I have since sealed the windows however the leaks continue when I travel in rough seas at an average of 12 knots. Has anyone had the same experience and has any ideas on what the cause of the leaks could be? Any help would be appreciated !
