I realize this is a few months old. Did you ever get your answer from Tartan? I have T40 number 63 and I have the inner headstay as well. Mine is backed up in the v-berth with a cable and turnbuckle down to the stringers. I have a
storm jib with hanks that I have never used. The previous owner told me he used it a couple of times, once in about 60 kts. off Cape Hatteras. I have runners, but I'm not sure where they should be rigged on
deck. On big
racing boats I've been on the runners were lead well aft and
outboard to the toe rail or a padeye. I'm thinking with these the aft end of the
Genoa track would be sufficient.
