smurphny - Thanks. The list is an offshoot from briefings that I've received when going to sea on Naval vessels. It's a practical list based on questions or situations that occurred over the years.
One item that I tell people verbally is that sailboats lean. It's what they do. The boat will not tip over because of 6400 pounds of lead in the keel and mostly because I won't let it. A lot of people don't know that.
I stress that if anyone wants a PFD at any time, they are to tell me immediately. We have inflatables that aren't hot or dorky and there is no shame in wearing one. I also tell them that nothing bad is going to happen to them because I won't let it. The goal is to come back with the same number of crew, not leaking anything red, and boat still pointy up front.
I once had a licensed captain compliment us on the pre-sail briefing that he overheard. That made my day.
