What are the consequences of improper thru-hull installation?

The consequences of improper thru-hull installation primarily include water intrusion into the laminate. This can occur if the thru-hull fittings are not sealed correctly, which allows water to seep into the hull. Once water penetrates the laminate, it can cause delamination, weakening the structural integrity of the vessel, and potentially leading to significant repairs or failure of the hull. This issue is critical as water intrusion can compromise the performance and safety of the boat.

Additionally, while there are other potential issues related to improper thru-hull installations, such as increased drag or noise, and possible structural compromise from other sources, the most direct and immediate consequence of a failed seal or incorrect installation is the risk of water entering the laminate. This is why the focus on water intrusion is particularly important in the context of maintaining the integrity and longevity of the vessel.
