On my SN I used a filet knife to cut the sealant of the windscreen/dodger, lifted it with a halyard enough to remove the hatch door. I replaced it with a plexiglass door - fantastic to brighten the main cabin. Removed the sweep so as not to scratch the plexiglass - no problem. See my posts on the subject from a few years ago.
