What this video covers
Mads repairs structural cracks and delamination on the deck and cabin tub of a 44-foot DIY catamaran project boat in North Carolina. Using a moisture meter, he confirms that the vessel’s foam core remains dry despite severe surface cracks, avoiding the need for extensive recoring.2:52 He grinds out damaged fiberglass using an angle grinder equipped with a dust shroud and 36-grit paper, then laminates patches using biaxial fiberglass and epoxy.3:39 For smaller core voids, he beds cut pieces of foam core with thickened epoxy rather than replacing large sections.9:42 To manage weather delays and future exterior work, he plans to construct a protective structure over the boat using shipping containers.22:09 He also prepares for a hull-blasting experiment to address surface imperfections.5:44 The project highlights that patient, multi-stage fairing with sanding blocks like the DuraBlock can achieve professional-grade results for non-professionals.16:44
