What this video covers
A Hallberg-Rassy 46 with a Seldén in-mast furling mainsail demonstrates the step-by-step procedure for furling the mainsail while underway. The boat sails at roughly 60 degrees on either tack to keep the sail loaded but not flogging.0:09 Before furling, the kicker is set so the boom sits just under 90 degrees to the mast; on a partially rigged boat, releasing the backstay tensioner slightly straightens the mast.0:13 The mainsheet clutch is closed to hold the boom steady, then the outhaul clutch is released to dump tension and create a deep belly in the sail — the target state is no pressure and no flapping.0:32 The outhaul is eased while the "main in" button is pressed simultaneously, feeding the sail into the mast.1:06 Progress is monitored batten by batten, pausing if needed to confirm each batten enters parallel — bottom and top batten tips tracking in together.1:36 As sail area decreases and pressure drops, the mainsheet can be trimmed slightly to prevent boom swing.1:52 Easing the outhaul and pressing "main in" together, while watching batten alignment, is the key to a clean furl every time.
