Hello, after a winter season in Greece with my IP 38 resting on dry dock, I discovered that the thin layer of fiberglass covering the ballast (concrete+iron) inside the bilge detached from the concrete surface by about 3/4”. I opened a hole and recovered almost a gallon on fresh water. I believe the problem was caused by condensation due to the particular weather in Greece. Relatively warm during the day but quite cold at nigh. The ballast gets cold during the night and stays cold during the day due to thermal inertia. During the day warm air gets in contact with the concrete surface, possibly because of some crack in the fiberglass, and releases its water content due to condensatIon against the cold concrete surface. I see two solutions. Remove all the fiberglass and reapply it thoroughly to avoid any air contact and subsequently cover the whole thing with some insulating material. However this job would be a nightmare because it would require removing the water tank. As an alternate, improve ventilation. Leave all floor hatches open, leave all portholes open under the winter cover and maybe have a fan or two connected to the solar panels and running all winter. Any suggestion?
