Check out some basic physics. A wave in a medium such as water is highly misunderstood by most people. The compression and rarefaction of the particles (i. e., water molecules, in this case - also bear in mind that water is an incompressible fluid) is almost entirely imperceptible out at sea (and I mean well out at sea). The breakers and what most people think of as waves occur only when the bottom of the wave starts to hit a substance even more incompressible, i. e., land.

Das Boot is a work of fiction. As a Lit major, I'm all for poetic license, but recognize it for what it is.

* German boats were smaller than US fleet boats. A smaller vessel will be more affected by sea state.

* Where you are is crucial. I respect the opinion of a sub vet, but notice where the boat was - in Long Island Sound in a hurricane. Shallow and enclosed; even a modern 350' long behemoth with the tonnage of a WWII CV is going to roll at a shallow depth.

In general, submarines do not roll, pitch, or yaw greatly under 100'. Furthermore, as far as SH3 and SH4 go - a great deal of the action in 4 occurs in 'blue water', away from a continental shelf. A lot of the action in 3 is above a continental shelf. This is a significant difference in what you can expect for sea state and weather, so maybe the devs have modelled it much more reralistically than one might think.
I happen to have a physics degree. Tsunami effects are a totally different effect than ocean waves. It has nothing to do with compressability of fluids.:rotfl: It does have everything to do with wave propogation, magnitude of the wave and relative depth where the tsunami wave is at the time.

These are two unrelated phenomena.

Before you flame a post, check your facts.
