Halyards
Warren your detailed advice on the headsail was well presented, especially 'pick a day with no wind'but sometimes there is no choice.Assuming he knew it slips out of the foil at the bottom.Right absolutely on keeping control of the halyard, with your teeth if necessary, but clip the shackle to the push-pit or stanchions, lifelines only temporarily. Never want stress, pulls, nor bends (like whence pushing a vessel out of a slip) on the life-line system. 1) not strong enough. 2) will crack the stanchion to hull bond, then you get water, read rot, into the balsa core.Use a piece of webbing attached to a cleat, toe-rail, or anyplace but the life-line system.
