I mentioned in the video, the cool thing is that we complicate everything by 1) having a different name for items on a boat vs those same things on land, bunk vs bed, bulkhead vs wall, block vs pulley and 2) everything on a boat has 2 names for the same item Capn Jack always called the bow line a painter.
British warships (roughly equivalent to WWII U.S. "PT boats" and the Kriegsmarine's "E-boats") had a giant steel "splash guard" in front of their forward deck gun. They called it a "wave guard". I would have called it a "knee-knocker".
Wooden Sunfish had a raised band of wood surrounding the cockpit they called a "coaming". (Which it would have been called correctly).
Fiberglass Sunfish have a raised bump surrounding the cockpit. Not quite a coaming--and so modest a bump--it could be called a "dribble guard".
