    so WTF it a deck roach? just a roach that lives/hides under decks, like slatted Teak decks that have space between them and main water proof deck?

    Is deck roach the athwartship curvature of the deck ? A term such as sail roach; the area composed of outward curvature of the leech. I have not heard that term applied to decks before. Camber is another word that is sometimes used to describe deck curvature.

    It's not listed in this photo, but the roach of a squares'l is the curve that gives it clearance when bending around the mast and other spars. It is the reverse of the roach of a fore-n-aft sail.

    For a deck, the term seems a little ambiguous since a deck often curve along two axis.

    In whatever case, the term can imply some degree of curvature. Deck roach it is then.
    Descartes would not call his curves roaches but his curves would be there anyway.

    Its a novel way to describe deck camber.
