A U-boat at 12 meters is at periscope depth, which is almost 40 feet. That means depth to keel. A Fleet boat is much larger (about twice in dimension and 3 times in displacement), so her depth to keel at periscope depth is about 60 feet. In both cases the top of the shears would only be submerged about 2 to 3 meters, almost close enough to disturb a still surface.

Not to belabor the issue but I found a British web site that covers their submarine service. I received an answer to a question I sent them, about depth.
The answer came from a Chief Stoker who entered the British Submarine service in 1952 where they were still using WWII standards. Their periscope depth was 32 ft. and the depth was measured from the surface to the middle of the hull. Later they went to Nato standards - that was like most Western Navies, and now measure from keel depth.
