New mast rake and prebend

[allene]

Two points. First, the old mast was wood and I cannot measure it as it exploded in the collision. Also, the new mast is aluminum.

Second. Just to be clear, the mast builder suggested that the mast such that with zero rake and zero prebend the adjuster all the way aft. In other words, straight under where it goes through the partners. Then applying rake would give prebend from that position and if that was too much prebend, the adjuster could be moved forward.
