As you are fom Greenwich,
and as I am from Greenwich, albeit Connecticut as opposed to your New Jersey, I have a kindered spirit to reply.Incidently, this is not the first time I have heard of Greenwich, New Jersey. Some time ago, an owl was raised here in Greenwich, Connecticut. After he was set free, he was noted to have taken up residency in Greenwich, New Jersey. Only goes to show that owls are the symbol of wisdom.Nevertheless, back to your problem.First, I think you are refering to your main halyard. The main sheet is employed on the boom and if that were to let go, I really don't think you'd have to climb the mast. Second, I think you are refering to the headboard at the top of the sail. The clew is at the end of the boom and attaches to the outhaul. Headboards are usually quite robust, so I am not surprised there is no damage there.I personally think it may be wiser to lower the mast to get the halyard back down than to climb the mast on a twenty-three foot boat. However, if you could secure one side of the boat to a dock, then I think you could climb up to get it. You should use the jib halyard secured around yourself or on boatswain's chair. You will need another person to work the jib winch to haul you up. That person will need to be strong, steady and able to quickly cleat down the jib halyard that holds you up. And also let you down slowly as well, unless, of course, you like leaving parts of your body on the spreaders.Finally, after you get the halyard down, attach a line to the shackle so that the next time you do this fun filled event, you need only pull on the line instead of going out and reacquaintaning yourself with the boys at Gold's Jim.By the way, how do you pronounce Greenwich down there. Is it like Green Witch, or like Gren Witch as we do up here.
