As regards the angle of a sailing ship when heeled over keep in mind the phrase "lee rail under" which describes a very extreme angle when sailing.

In 1972 I served on the USS Compton (DD-705) out of Boston Harbor. During one storm I remember watching the list indicator while on watch in the engine room. We recorded a list of 42 degrees. As I remember we were holding on to anyhting cool enough to touch as we waited for the old girl to come back on to an even keel.
