What this video covers

Structural rot in the forward deck of a catamaran requires extensive fiberglass and plywood repair after water infiltrated through poorly sealed deck cleats and chainplates.2:34 The owner discovered the damage while investigating persistent moisture and soft spots near the bow.1:34 Initial inspection revealed that inadequate backing plates for the deck hardware allowed movement, which compromised the sealant and permitted water to saturate the underlying plywood core.3:04 While some structural reinforcements remain sound, the owner must cut away large sections of the deck laminate to remove rotted wood and replace it with new core material.17:00 The repair process involves grinding away fiberglass, assessing the extent of the decay, and re-laminating the deck surface.15:00 Tropical weather systems and heavy rain further complicate the project, forcing the crew to keep the work area covered to prevent additional water ingress.19:41 The owner notes that the damage likely accumulated over a long period, despite a previous survey failing to identify the issue.13:57 Learning to perform these structural repairs independently provides a practical solution to the ongoing maintenance challenges of the vessel.13:57
