In case this is still an open question, I just went through this. Have Lewmar
low profile size 10 hatch
. Latch broke at the piece glued on the hatch
lens. Latches are glued on at the factory and was not able to find anyone that can re-glue or help. There are (were) 2 options:
1. purchase a new new lens. The lens has a gasket and the frame is split (2 piece). Separate the 2 pieces of the frame, slide out the old lens and gasket, slide in the new one and reassemble the frame.
2. purchase a new hatch
and swap out the tops by pulling the hinge
pins. Not cheap but goes fairly easily.
I went with number 2 since it is pretty cold here and i wanted it to go quickly and didn't want to fool with the gasket in the cold.
Right after I finished I learned from Lewmar
that they have now changed the design to bolt through latches and going forward the latches will be replaceable without replacing the lens. Obviously some suppliers will be trying to move the older glue-on models so try to get replacement lenses or hatches
with the new feature if you think the latches will break with any frequency. I have only had one out of 8 break so far and I have no idea why it broke.
Hope this helps.
