Does anyone have experience of this and has successfully fixed it?

If you have the same hatch as me - Lewmar I think - the leaks we have had are through the handle axle / spindles. If you take these apart there are O rings which can be replaced and cure this problem.

Hope this helps

Thanks for the post but we have already done this and I can watch the water coming through the seal! It is definitely a Moonlight hatch (made in Denmark) not a Lewmar.
