I need everyones help with this engineering problem.....
I am looking to engineer a "lifting tripod" to lift the Nacra mast just high enough so that it reaches past that critical spot where the winch attached to the forestay will lift it vertically. The challenge has always been to be able to lift the mast solo in a controlled way (so that you could stop and anytime to untangle stays or trapwires that invariably catch on something at the most inopportune time) with very little physical strength necessary.
I think first if I could set the mast on the ball and rest the other end on this tripod contraption that is set up maybe 5 or so feet behind the boat on the trailer, and then second attach the winch line to the forestay, and then third lift the mast with a pole that slides up thru the center of the tripod high enough (say 10 feet?)and have it stay there while I could walk to winch to begin cranking I think I would be golden. It would be cool if the lifting action on the tripod could be a winch-type crank too rather than brute force but how to do that completely escapes me.
So what do you think? Maybe someone already does this?
Maybe it would be easier to just engineer a gin pole to change the angle and reduce the amount of lift required to get the forestay winch action to lift rather than pull?
Getting it up is one thing.....and what normally everyone seems to worry about in these discussions but what I want this to do as well, is make it easier and safer coming down. I'm not sure if the Gin pole arrangement qualifies on that account.
Your thoughts?
I am going to try the boat reversed lever idea already posted in this thread but this tripod approach means less changes to the current system.
Thanks
