I'm not so sure the exact size ship we speak of. But if you recall back
a long time ago when the original poster spoke of a hypothetical wire
not working at 4 feet underwater. I even suspect that a 30 foot vessel
might take greater than a 4 foot excursion, especially in your neck of
the woods!

It really doesn't matter if the vessel has a draft of 4 feet or 24
feet,as the coupling to the seawater is to the hull/water boundry
which is the same as the surface of the water from the RF point of
view. Skin Effect, or Skin Depth @ any frequency is a Surface Effect
and that surface is the hull/water boundry, for any hull material.
