    ISO 11812 requires a top of sill height of 200mm for design category A.

    To me it is not clear from these rules whether it is allowed to acquire a sill height of 200 mm with help of the fixed profile of a hinged/sliding doorsystem, which has been attached watertight to the steel sill of the hull. See also attached figure "sill height.gif" to clarify this.

    The question is now: Is Situation 2 allowed?

    Your help is highly appreciated.

    "The sill height is the lowest height of the openings considered to be sills."
    So yes, 2 is allowed..

    This is the definition of "sill"

    Yes it is confusing. I suppose 2 is OK, but someone can find it wrong, since the sill as to be under the door.
    Anyway play safe.

    I used to be on ABYC's cockpit and scuppers committee, and from my understanding of it #2 is the correct way to do it.
