I bought a used Hobie "under the bridle" furler. Has anyone used one of these on a P-19? From just briefly looking, it appears that due to way this furler attaches, once the furler is attached to the bridle wires, the furler will actually bring the sail tack up an inch or two. I'm also guessing I will have to shorten the "upper forestay" by this measurement as well as the length of the upper swivel which is 2 5/8" pin to pin. Does this sound correct? I'm guessing there are a couple of different ways to do this, I just want to keep it as painless as possible.
