If the water is getting down between the glass and the seal (or the frame and the seal, then a fool-proof solution is as follows:-
Go to Marine Superstore (Port Solent) and buy a tube of ABROMAST sealant (it’s a non-hardening butyl).
Squidge a line of it around the outside of the hatch and use your finger to push it into the gaps around the seal. Wipe the excess off with white spirit.
Job done. They’ll not leak any more.

PS. If you find that your hatches or windows start to leak from the foam frame gasket, remove them and re-seat them using this stuff to replace the foam gasket. Done all mine and the boat is now dry as a bone.
