The deck fitting for the forestay on my Capri 18 has four holes in it. One is located on a vertical tab at the front, and the other three are located on the horizontal tab. Can anyone tell me which hole is used for the forestay, and which hole is used for the headsail tack? Obviously the headsail tack will be attached aft of the forestay, but that still leaves me with a few different combinations. This is not addressed in the manual at all.
