O que este vídeo aborda
Fairing the 50-foot custom sailboat hull requires removing approximately 100 square meters of peel ply before applying a fairing compound.0:37 To achieve a fair surface, the builder avoids random orbital sanders, which follow existing dips and bumps, in favor of longboard sanders from Flexisander.3:25 These tools bridge low and high spots to ensure the hull remains true to its lines.3:32 The builder tests two application methods: the standard technique of applying a thin coat of epoxy compound followed by guide-coat sanding, and the notch-trowel method, which creates epoxy ridges to reduce the surface area requiring sanding.7:40 The fairing compound consists of West System 105 epoxy mixed with 407 low-density filler.10:37 Initial tests suggest the notch-trowel method may consume excessive epoxy—potentially 75 to 80 kilograms for the entire hull—and requires precise spatula groove sizing to avoid unnecessary material waste.21:57 The builder plans to refine the filler-to-resin ratio and technique through trial applications before proceeding with the full hull.24:07
