But you do have a deck core (I assume) and water can run inside that. So it's possible.
That said, chainplates are high on the list of things that leak on a boat given the geometry and the amount of flexing they do. So if you have a chainplate leak it probably really is the chainplate. But you never know.
Also, what about those screw holes? A leak in the screw hole could come out the chainplate inside.
