I haven't got it setup yet, but the first owner had one setup on it, so some of the parts are already there.
I'm using a "standard" pin on a plate rivited to the front beam to attach the pole. and using a cam cleat on the front beam for the halyard as it is already there.

If you look at the performance F-18/N-20 manual it will give you some good ideas about how to set it up.
