    What does Wet Deck refer to? I have a blur idea that it is the bottom plate of the cross-platform structure of the catamaran. Is it correct?
    And is it possible to discard the bottom plate of the cross-structure, rather keep only the deck plate of sufficient thickness and, attaching adequate strengthening members onto the deck plate?
    Thanks,

    Wet deck is uncovered deck area (usually self draining through scuppers). It's usually a term used for commercial fishing vessels (mono and cat) and refers to the area where the nets are emptied and the catch processed. Coz it gets wet.

    Correct. A catamaran has structure that connects the two hulls together. This structure is called a raft or bridging structure (or others). The upper most deck plate, is the main deck and generally spans the whole beam of the vessel. The lower plate, between the two hulls, is exposed to the sea and thus called the wet deck plate.

    Anything is possible, but you have to design it and still satisfy the strength and deflection criteria.

    Leaving off either the top or bottom plate will make the structure heavier for the same strength. Assuming you properly design it.
