If I'm expecting to be piloting I'll bring my own binocs, there are never enough on a boat and everyone is happier when "their" own good ones aren't being passed around.
But even when I'm traveling light, I'll carry my own handheld VHF. I know it *works* and after a boat is locked up and someone says "Didn't YOU call the launch?" it is always easy to pull it out and make the call.
In early/late season, I use a "jeep hat" instead of a watch cap. Five years ago you couldn't find 'em at all, now they're available all over. Like a watch cap with a short bill on it, the kind worn by Radar on MASH. Very handy to keep a low sun out of your eyes when you're trying to look aloft at the sails, and much warmer than a baseball cap.
