What is one consequence of osmosis related to corrosion in boats?

One significant consequence of osmosis related to corrosion in boats is blistering and separation of protective coatings. Osmosis occurs when water penetrates through a material, such as fiberglass, and creates pressure underneath the surface. This infiltration of water can lead to the accumulation of water and other dissolved substances, resulting in the formation of blisters underneath the protective coating.

As the pressure builds, these blisters cause the protective layers, such as gel coats or paints, to lift or separate from the substrate. This can ultimately expose the underlying materials to moisture and environmental conditions, paving the way for further corrosion and degradation of the structure. This process compromises the integrity and durability of the boat, emphasizing the importance of proper maintenance and protective measures to mitigate osmosis and its damaging effects.
