    In general, if a vessel design has always been classed by an IACS society with a navigation notation of "coastal area" and then the designer wanted to design it for "unrestricted navigation" what would be some of the implications?

    • Scantlings increased
    • Skin thickness increased
    • Rating of glazing
    • etc.

    The changes can be many and very large: scantlings, freeboard (bow, center and stern), stability, safety, fire fighting, points of possible flood, navigation equipment, ...
    I think you should go point by point, along the regulation applicable to the boat, comparing what the boat has and what the new regulation requires.
