Mensch, this reminds me of when I took a whale-watching cruise to the Farralon Islands, nearly 30 mi. outside the Golden Gate. An all-day trip. Miserably cold, bobbing up & down like a cork -- the only thing worse was going below, to be met with a greasy food-like stench. The risk of nausea was worse inside, so I spent most of the day on deck. In retrospect, a dilemma endured by many a U-bootman, no doubt.
Yes, we saw whales -- close enough to get sprayed when they exhaled.
