I just spent the last hour of my night watch waving my zebra striped birthday Type IV flotation device at boobies who were trying to land on our solar panels by moonlight.
The first booby that I noticed had already landed. When I came up to scan the horizon, it made a noise and scared the bajeezus out of me. I grabbed the first thing at hand (the cushion) and batted at it. After whacking that booby off the boat, I watched their flight pattern, realized that they were coming in only from the port side, into the wind, and flaring up at the last minute to try to land on the rolling boat, and stood there watching the port side and swatting at them.
I am a vicious booby deflector. My arms are actually sore from holding the flotation cushion over my head. The next time someone asks what I do on night watch, this is the story that I'll tell.
