What this video covers
Leon Schulz operates the in-mast furling mainsail on a Hallberg-Rassy 46 by manually synchronizing the electric furling motor and the outhaul winch.1:36 To ensure the sail deploys without jamming, he maintains the boom on the centerline with the mainsheet tight and eases the backstay to keep the mast upright.3:31 He avoids heading directly into the wind, instead positioning the boat between 40 and 70 degrees off the wind to allow the sail to unfurl under light pressure.2:43 Schulz monitors the mast exit slot through a transparent panel in his Bimini to verify that the sail and its vertical battens clear the housing smoothly.1:03 When the Elmström logo appears, he knows the sail is fully deployed and stops the furling motor.4:11 He then releases the mainsheet to depower the sail before tensioning the outhaul to set the final shape.4:53 Practicing this sequence in light winds prevents jams and ensures the sail furls back into the mast cleanly.5:49
