Here's some advice regarding that for when/if you get seasick the next time out...being INSIDE a moving boat is the worst place to be. Your inner ear senses movement but you cannot orientate on a horizon. That is what causes the nauseous feeling. You'd do better sitting in the cockpit/flybridge outside while the boat is moving.
Someone said upthread that there are a lot of beautiful places you can't get to on a boat. Well, yeah, but there are plenty of beautiful places that you can ONLY get to on a boat! Lucky is the man who can do both!
With a boat you can skip the train to Hawaii.
Unfortunately, it doesn't work in my case. I seem to have a peculiar affliction for a certain type of motion that only occurs on the ocean, or a body of water connected to it, such as a large bay. I'm not sure what it is, but I think it has something to do with the ocean's swells - the heaving motion.
As long as a boat is moving fast, 12+ knots or so, I don't experience any motion sickness, regardless of wave height. When the boat slows, or stops I get sick.
I'm a pilot and have no issues with motion sickness while flying, even if performing maneuvers that would make most queasy. Stick me in or on a body of saltwater (freshwater lakes don't bother me) and I get nauseous every single time. I have tried to overcome it dozens of times, but nothing has worked so far.
I think when my ancestors came to America, many centuries ago, the trip must have been so horrible, the memory of that experience somehow embedded itself into my genes! lol
