Oh man, I have just gone through experimenting with rake on my recently modified Hobie 14 turbo. ( before , it was just a regular H-14). I put the 7 hole adjuster between the top of the jib, and the swivel at the top. Putting the adjuster on top of the furler, would have put the jib way too high. ( It sure looked awkward). It was a real pain to adjust the rake, since everytime I wanted to change the length in the adjuster, I had to drop the mast. But, I am running at the 4th hole in the adjuster, and the rake seems to be just right now.
I am real curious, if any other H-14 turbo sailors rake their mast in the same way??? Its not elegant, but it works.
