The 2 pics above show the issues I tried to describe. At the #2 panel the hatch edge is lower than the body on both sides of the teardrop.
At the number 3 panel, there is a gap of about 1/2″ between the hatch and the teardrop body.
Some time ago I saw a picture on the forum showing an edging of fiberglass around the hatch opening. The text expressed annoyance at having to use fiberglass to fill a gap but there wasn’t any further comment or explanation that I could find.
