I am trying to mount a compass to the tramp centerline just behind the mast. I was thinking of attaching grommets to the tramp and then mounting / dismounting the compass for racing. The question is can you attach the grommets on a rigged tramp (due to the tension on the fabric) or do I have to remove it and install the grommets?.

I was told I could use a hot nail or such to melt small holes in the tramp and use them to mount the compass.

Its a new trap so I am a little hesitant about any perforation...
