How about having a simple loop of string you could put them on, and put this around your neck when you head off to sailing, or start rigging..maybe put it on a loop with the box keys if you have. This way, they'll be dangling aroung your neck until you put them in. Only thing is that you would have to get into the routine of putting them back on the loop afterwards <img src="http://www.catsailor.com/forums/images/graemlins/confused.gif" alt="" />
I once asked a friend to put them in <img src="http://www.catsailor.com/forums/images/graemlins/crazy.gif" alt="" /> This resulted in a lost plug and the boat drifting to the far shore before being drained and sailed back with a plastic bag to help <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />
