Then somebody THOUGHT they saw a spout, so they decided to run the boat in circles, slowly.

Then I DID get seasick, but there was no "run up on deck and puke over the rail", because the first deck was completely enclosed and the second deck was half enclosed, so if you puked from there you'd be decorating the windows on the lower deck. So, I had to sit as close to the center of the first deck as possible with a barf bag. I remember thinking, "If the boat sinks now, I might die, but at least I won't feel like this anymore."

As we headed back in, as soon as we passed Point Bonita, I immediately felt better and within a few minutes I felt completely fine. On other trips on the Bay, I've never had any problem.
