    We have had big rain lately and water is accumulating in the channel where the sliding hatch over the companionway goes under the fixed part of the hatch. When I open the sliding hatch, water comes pouring into the cabin from above where the slider comes out from over the coach roof, beneath the fixed part of the hatch. The slider is actually pulling water that has collected between the coach roof and fixed part of the hatch out. My boat is a 1987 MkII. Friends with MKI have visible drains at the forward end of the channel that allows water to drain. I don’t have that drain. I only have a drain at the aft end, near the winches. The issue is that the channel actually slopes up here.

    Now, water does seep out through at the forward corner, but the fixed part of the hatch is caulked at the forward end, if not by factory then by a previous owner. Is it possible there was a drain that has been sealed? I know the MkI is different. Would love to hear if any MkII owners have this problem.

    BTW- I have learned that if the sliding hatch, when closed, rests on the hatch boards and is pitched forward, the problem is worse. Even when it sits correctly, I still get some accumulation.

    When/After a rain I have to open my slider slowly or I have the same problem.
    I haven't looked for a drain or even why it happens.
    The forward edge of the fixed portion is caulked on my boat.
