Dry bilges on classic Bertram Sportfish: Preventing future hull blisters
Experts in the marine industry will often tell you that blisters on the hull or osmosis are from moisture entering into the laminates from the inside -- i.e. the bilges. Maintaining the bilges in a dry state allows the fiberglass to breathe and the built up moisture to evaporate out. This becomes even more critical in a northern boat where that moisture, as it freezes, expands and causes cracks in the hull. The small investment in the Arid Bilge System has the potential for real long term savings.
