    we can exploit the deck water,but it can make a trouble,There is also the grey water tank with an excellent strainer

    sure its all by the thru hull
    But I still confuse,I must conserve the strength of bottom panel,so I don't want to make a thru hull for each system's''machinery cooling, sanitation, air conditioner,descharging''it can make the hull weak.

    Good...so why ask me then?

    Now you need to decide whether you wish to use a sea chest or individual inlets.
    That's YOUR call...

    That is a separate question.
    You cannot address this until you decide how you will arrange the SW intakes to the vessel's systems.
