    Welcome to the Forum Jo Ho.

    You will not get any replies to such a vague question - you need to supply some more information.

    The simple answer to your question is all the types you mention are / can be used - it all depends on the usage, boat type, speed, etc.
    What kind of 20 metre high speed boat are you interested in?
    And what type of material - exotic composites, ordinary fibreglass, aluminium........ ?
    What does the boat have to do? Is it for commercial work, or is it a pleasure yacht?

    Thanks for caring,
    It will be used as a search and rescue boat, can reach up to 30 knots, and using aluminum material.

    At that size and speed it will most likely be standard frame and longitudinal with deep longitudinals aft to carry the engines and gear train. The trade-off between frame depth and longitudinal depth will depend on plate selection, compartmentation (i.e. bulkhead and tank location), self-saving features, etc.
