If the rig is already in the boat, jumpers also need to be tuned first, after slacking everything else. They are quite a lot of work either way, usually requiring an extra trip or two aloft, but there you are.
With no backstay to oppose them, I would think there would at least be runners. I'm not familiar with the boat; would you post pictures?
Fair leads,

Since the negative bend will depend on the tension you put on the jumpers, is there any way to determine how much tension should be given before stepping the masT'

Thanks,
