Is this the system you have? Or something similar where the mast support is acting as the gin pole? The trap wires stabilize the mast.
https://westcoastsailing.net/hobie-mast-stepper/This is the system I use now, attaching the gin pole to the mast. I made one similar, years ago, with a 2x4 for a gin pole, for a Hobie 17. It worked just as well as this fancy one I have now! On my homemade one, I used the trap wires for stabilizing the mast. The factory system uses cords that attach to the main halyard and attach to a slug that goes in the sail track. My old system was faster!
