    Welcome to the forum.

    There's nothing easy about removing rotten parts. If you pry on it, it'll crush, if you tug at it, it'll break, etc. Generally, when things are bad, you shore them up with temporary bracing, so it can be removed wholesale, but with the security it'll stay together for a rebuild. This is often easier said then done, as it's hard to attach something solid to rotten elements.

    We'll need a lot more information, to provide more than generic and obvious advise. Photos of the concerned areas would be helpful too. Cabin removal should be pretty straight forward. Reinforcement in questionable areas also should be relatively straight forward, given some common sense and experience.

    we've build boat from 14' to 61' and have replaced cabin are several others both wooden and fiberglass hulls.
    with this one its the first one we seen with bolts of cabin to hull, the least amount of cutting is better, sort of looks like it the bolt will come out that the cabin should be able to lift off the hull, just wondering if someone knows
    if that true for the Marine if thats how the finnish builder designed it??

    Again, removing a cabin is pretty straight forward, if you've got some experience with this sort of thing. Some are designed to come of, if only for transport, others not so much, but without knowing what you're working with, I'm not sure how to help.

    Hard to say. Post a picture.

    Destroying things is easy and fun.

    A bolted on cabin is probably also adhesive bonded. Unbolt, pound in a wedge then cheese wire the bedding.

    You should carefully consider any change in the boats shape that may occur when removing the cabin. You may want to add structure before you remove the cabin.
