What this video covers
Mads strips the hull of his sailboat, Athena, to address widespread osmosis and a failing barrier coat.0:04 He evaluates several sanding tools, finding a heavy-duty belt sander most effective for bulk material removal, while a random orbital sander provides a smoother finish.3:28 He attempts to use an angle grinder with a sanding adapter but struggles to source a large-diameter version locally.4:28 To manage toxic dust, he connects his sander to a vacuum with an extended hose and wears a Type 5 protective suit.5:05 During the process, he discovers wet voids in areas previously repaired with fiberglass, noting the trapped liquid lacks the acidic, vinegary smell typical of osmosis.2:25 He monitors the hull’s moisture levels using a non-destructive GRP moisture meter, planning to delay further treatment until the readings drop significantly.7:58 The project highlights the difficulty of managing osmosis on older hulls and the conflicting industry advice regarding repair methods.8:40
