What this video covers
Leon Schulz demonstrates the manual emergency furling procedure for a Seldén in-mast furling mainsail on the Hallberg-Rassy 46 Regina, covering every step needed when the electrical motor loses power.▶ 0:02 The first step is disengaging the electric motor from the gearbox by pressing a release button and rotating the motor sideways.▶ 0:24 The worm gears are then engaged by pressing in and turning the manual drive shaft three or four turns until resistance confirms engagement.▶ 1:15 Because the standard Seldén handle is too short to clear the adjacent winch, the boat carries a welded extension piece that fits the drive socket.▶ 0:57 A faster alternative is a standard tool-bit adapter — available at any hardware store such as Bauhaus — that accepts the drive fitting on one end and an electric drill chuck on the other, allowing the drill to spin the sail into the mast.▶ 2:18 Throughout the process, the outhaul must be simultaneously eased, ideally by a second crew member in the cockpit; a nearby winch allows a solo sailor to manage both tasks.▶ 1:50 Returning to electrical operation requires disengaging the manual drive in the correct sequence — pulling the adapter anti-clockwise, then turning the shaft until the spring-loaded screw releases — before the motor re-engages cleanly.▶ 3:15
