Let's see I was on the Chesapeake in almost windless hot day down near Tangier with some kind up gnats intermittantly biting me. One bites me on the temple and I give it a good slap which kills the gnat and also launches my brand-new prescription sunglasses into the bay. To which I declared, "F***, sh**" and then relaxed.
Just north of there I went below thinking I had the boat all nicely balanced, as I came back up on deck the boat jibed knocking my Tilly hat into the bay and breaking my non-sunglasses. Spent an hour or more tacking back and forth trying to find the hat without success.
To save my tools, I have adopted the lanyard approach or at least the full consciousness death grip on the tool in use.
