Lewmar coastline hatches are quite weak and the catch blocks are held on with just two pop rivets. As such those rivets can be bent over time and the seal on the hatch will not keep water out anymore.
This is an attempt to improve the compression on the hatch seal. It has not been tested yet, but I will give updates if it works.
There is a range of different sizes from 1 to 6 mm thick.
