What this video covers

A 44-foot catamaran restoration project faces a setback after the discovery of thousands of small pinhole voids in the hull laminate below the waterline.2:48 These pits, which appear only in submerged sections, likely result from osmotic pressure causing tiny air voids in the gelcoat or laminate to burst.11:04 While the issue is cosmetic rather than structural, it complicates the application of a future barrier coat and antifouling paint.11:41 The host considers two remediation strategies: spot-filling individual pits or performing a full gel-plane of the hulls followed by a new layer of fiberglass and epoxy.22:05 The project also involves installing dripless shaft seals, reinforcing through-hull locations with 1708 fiberglass cloth, and fabricating 3D-printed guides to ensure symmetrical, flush-mounted skin fittings.14:42 The host plans to consult other owners of similar vessels regarding the proper routing of vent hoses for the shaft seals to prevent water ingress.26:02
