What this video covers
Dan and Kika are relocating the mainsheet traveller on their sailboat, *Uma*, to a position forward of the hard dodger.▶ 0:00 This modification allows the crew to run all reefing lines and mainsheet controls to the cabin top winches, enabling them to reef and trim the mainsail from the protected cockpit area.▶ 0:05 Because the new traveller position is closer to the mast, the mechanical loads on the hardware are doubled, necessitating the installation of heavy-duty, cast-aluminium Schaefer traveller pods.▶ 2:50 To ensure the traveller clears the companionway turtle shell, Dan fabricates custom pedestals from 10mm G10 fibreglass laminate.▶ 3:31 He replaces the deck core with G10 at the mounting points to provide a robust, through-bolted foundation.▶ 4:12 By using G10 inserts and structural epoxy for deck hardware, the crew eliminates 74 potential leak points that would otherwise require through-bolting into the cabin interior.▶ 24:45
