I am not comtemplating acutally doing this and I don't have a specific boat in mind it was just a question that came to mind as I was reading more about different rigging. As I read your feedback I think that I knew the answer before asking the question but now I have confirmation of sorts. I guess better questions would have been 1)does the mast need to be repositioned and 2)is it a worthwhile task to perform (would the benefits be worthy of the task so to speak). Apparently the answers are yes and no as I suspected.
Thanks for your thoughts.
