What this video covers
After discovering thousands of osmotic blisters on the hulls of their Lagoon 450, the crew spent 10 weeks in a Malaysian boatyard performing extensive fiberglass repairs.0:31 The blisters, concentrated along the centerlines, required grinding three layers deep into the hull laminate.1:38 To prevent recurrence, the team rebuilt the affected areas with epoxy resin, which they note is superior to the original polyester construction.0:54 Following the repair, they applied six coats of Total Protect epoxy barrier coat to ensure a waterproof seal.5:04 The process included scuffing and sealing the rudder stocks with epoxy, installing isolation pads to prevent galvanic corrosion between bronze through-hulls and copper-based antifouling paint, and applying ablative antifoul.11:35 Upon relaunching, the crew managed a starboard sail drive failure during close-quarters maneuvering by utilizing the port engine and coordinating with the marina manager for a T-dock berth.21:58 The project highlights the necessity of a proper barrier coat to protect gelcoat from water intrusion.
