When I purchased a used Laser I knew it weighed 144 pounds which was about 14 pounds more than desired. I installed an inspection port beside the centerboard slot and discovered that one of the three flotation "bottles" was half filled with water! Emptying that out reduced the hull weight to 140 pounds. Now I am wondering if the flotation in the rear of the boat might also be filled with water. Has anyone had that problem before? If I were to install another inspection port to check that out, what would be the best location for it? Thanks in advance for any ideas.
