Typically, there is an eyebolt on the front of each bow, just under the cross beam to tie the bridals to. The typical length of each bridal seens to be about the beam of the cat, perhaps a bit slimmer (this is based on a lot of searching online and a bit of my own experience). When I started, the bridals seemed awefully long. Not a big deal. For my cat, one of the key things was to ensure that the length prevented the bridal from hitting the wires attached to the
bowsprit.
