What this video covers

Johan and Malin continue the build of their 50-foot sailboat by preparing the interior hull for fiberglass lamination.Watch After removing temporary support frames, Johan fills screw holes and uneven areas with thickened epoxy to prevent air bubbles from forming beneath the laminate.10:42 He marks the hull for chain plate reinforcements, which will consist of 1200-gram unidirectional fiberglass cloth applied in a band to handle compression loads from the stays.4:30 The keel area requires a solid glass thickness of over 20 millimeters, necessitating 25 to 30 layers of 600-gram fiberglass.7:59 To mitigate the risk of air bubbles caused by high ambient temperatures, lamination occurs during the late afternoon and evening when the barn temperature drops.10:34 Johan uses a saturation table to wet out the heavy unidirectional cloth before application.12:26 He opts to laminate directly onto the cedar core without a preliminary epoxy primer, finding that the wood does not excessively absorb the resin during cooler evening hours.16:19
