Hi All. I’ve been having an offline conversation with Josh, see below. Perhaps someone else might like to answer Josh’s questions as I can’t…

The original poster was asking about placement of wood blocks. He had all 4 blocks forward of the mast and the mask back all the way aft. I assumed that in moving the blocks to move the mast forward that this would move the foot forward as well. No mention of changing headstay length so I assumed it to be the fixed point in all of this. Based on these assumptions the trailing edge of the mast and the luff edge of the sail would also move forward but the mast as a whole would have more rake. Right?

Since the luff is attached to the trailing edge of the mast, if the mast rake increases the luff must move along with it. Perhaps someone else can make more sense if this than I can for you. I'm at work but will post our conversation to the masses when I get home.
