We have a 2003
Beneteau 411 and cannot get the hatches open. They are stuck fast. The
boat did not come with a proper key for these hatches either which makes it difficult, and we do not appear to be able to source one anywhere. Does anyone have any tips on how to open these please? The lid has an indented cross on the top which a key would slot into. We have cut a piece of laminated
wood to fit and tried turning it but it won't budge. A solution would be very much appreciated as we have been unable to inspect our
water tanks and there could be a monster in there and we would not know!
