BIG difference between my first boats - WW-II diesel boats - and the later and new nuclear ones. A nuclear submarine is a complete, independent enclosed city - except for food. 98% of the time you have no idea you're 100 or 1,000 feet down. During high speed (excess of 25 knots) maneuvers the sub banks into turns, nose up, nose down depth changes - just like aircraft except in a much denser, slower environment. A missile boat, dead stop, hovering at launch depth, is dead flat and quiet. When one of those 80,000 pound Polaris/early Poseidon birds leaves the tube the entire 8,500 ton boat flexes a few inches in the middle and the thump of the gas generator will wake the dead. (The missile motor does not light off until after the bird clears the surface - the bird is "shot" out of the tube by a huge slug of high pressure steam created by a small rocket motor firing through 100 gallons of distilled water) We can launch a bird every 32 seconds, if need be. The sound of the automatic depth control system (80,000 or more pounds is a LOT of instant weight change) is fearsome - with air, hydraulics, water, missile tube hatch closing all in their own orchestra.Sub, I think a ride in submarine would be a rush, too, but I'm very claustrophobic so not sure how I'd respond inside one.
