The jib is close, but it is a work in progress. We are starting with existing front stay mounts to set the cross bar since this does not require any modifications to the hulls. Also, the original G-cat rig did have a lot of jib overlap (damn near a genoa.)
The hulls came with just crossbars, tramp and traveler with the rest coming from our totaled G-cat.
This is phase 1. Long term it will have a square top main and high aspect jib w/ spin.
If it sails respectably with this rig, next step will be to get the spinnaker working.
