Rebedding

Rebedding is a maintenance process commonly associated with boats, specifically the sailboat keel. It involves removing the keel, cleaning it, and then re-securing it to the hull with new bedding material. This is typically done to address issues such as leaks, keel bolt corrosion, or to improve the integrity of the keel-hull connection.

The primary purpose of rebedding is to ensure a watertight seal and a strong structural bond. Over time, the sealant used during the initial keel installation can degrade due to stress, vibration, and exposure to saltwater. This degradation can lead to water ingress into the hull, potentially causing rot or delamination, and weakening the keel attachment.

The process usually begins with the boat being hauled out of the water. The keel is then carefully detached from the hull. This can be a challenging step, as the keel is a heavy component and may be held in place by keel bolts that have corroded or seized. Once removed, the keel and the mating surface on the hull are thoroughly cleaned and inspected. Any signs of corrosion on the keel bolts or structural damage to the hull are addressed.

New bedding compound, often a marine-grade sealant like polyurethane or epoxy, is applied to the mating surfaces. The keel is then reattached to the hull, and new keel bolts or nuts may be installed. Proper torquing of the keel bolts is critical to ensure even pressure distribution and a secure fit. Finally, any excess sealant is cleaned up, and the area is checked for a watertight seal before the boat is relaunched. Rebedding is a significant undertaking but essential for maintaining the safety and structural integrity of a sailboat.
