Re: Mast \"A\" frame construction ....
Nigel,having done this a few times using whatever is around ,I would suggest you need 2 poles 4metres long(actually 3m would do with someone hanging on the mast foot to counter its top heavyness as you swing it vertical..... can you get a couple of 4x4 posts?Lash/bolt em together at the top,rig a block and tackle to a strop around the mast just BELOW the spreaders,and tie the post feet to the shroud points on the deck.
We once pulled the mast out of a 35 footoer by sandwiching it between 2 boats and using both of the outlying boats' main halliards,again led to a strop below the spreaders and tied at its tail down to the mast winch to reduce the load on the spreader feet.Worked a treat
Why argue with a nautical wall? I just read the graffiti these days.
