    This is more a question for our designers that create CNC files for metal cutting, When you are nesting parts what size plate are you thinking about ? ? the largest one can get or the more common 4'x8' ?

    The size of plates that a shipyard uses is a question that depends on several factors, mostly for constructive reasons, rather than the preferences of the designer. For example, the power of the cranes will determine the maximum size (weight) of the blocks that make up the hull, which in turn will define the maximum size of the plates.
    The size of the pieces of the boat can define the size of the plates, when looking for the least possible waste.
    At other times it may depend on the type or the price of the material in the warehouse of the plate supplier.
    Always, when working for a shipyard, you have to ask them the size of the plates that best suit them.

    It really depends on the shipyard since a crucial factor is the bed size of the cutting machine(s) in the shipyard, which will limit plates to a certain length and breadth. Block/unit size does influence the size of plate to an extent, but more often than not shipyards will order plate by the tonne and the size of plate becomes almost irrelevant. Of course, if the majority of the blocks happen to be the same length, then ordering plate to that size is favourable.

    Tansl,

    Thank you sir I should have been a little more clearer in my question, since I was thinking in the + - 40' size vessel, not a massive ship.

    more in the line that a small yard, and or home builder could handle. and be truckable legal loads,

    Think, then, of the size of plates that are in the nearest store or in the cheapest ones you can purchase.

    Thank you again sir, what your saying in essence is find the material and cutting location before ordering the plans and or having a designed commissioned,

    Yes, that's basically it. Always, when designing a ship, you have to do it thinking about who is going to build it, what construction system is going to be used and what material and human resources are available. The same boat, made in different shipyards, may require different drawings, different information.
