Hello fellow sailorsThe ballast tank is vital to seaworthiness of my beautiful Hunter 26. I want to ensure that the tank has no defects, or damage made by pervious owners. I am pulling her out of the water in a week’s time, and want to prepare all needed inspections, and improvements in advance.Any good advice concerning the ballast tank? How do get eyes on?PS! Thanks a lot for previous advice concerning the heavy rudder. Now I can steer with only my pointing finger
