One thing I learned about the sea quickly - it's unpredictable. But I grew up in Chicago where they say, "If you don't like the weather, just wait ten minutes."
I've done some rafting and I've been asked to remain tied overnight. My thoughts immediately go to the worst case scenario. And then I say no. Whatever the "advantages" of remaining tied up are, the disadvantages overwhelm them. We can always get back together again in the morning, as long as we're still floating.
