Just smile and go on, admit nothing! Well, we all forget things, like ICE, the drain plug, clean out plugs, lanyard, throttles in neutral, etc. We usually only forget those things once! After that, we adopt better checklist discipline, or we just use the mental note technique, until the wife or kids interrupt our mental note technique!
I forgot I was dangling my box anchor 10' deep to clean it off before full retrieval. OUCH! I generally dangle it there and run at low speed no wake mode for a few minutes to clean it off. It works like a charm...unless you forget about it nd either increase the no wake speed or take off! I did neither, I mistakenly set a no wake speed of greater than low, and that was enough speed to get it to bounce off the hull. Luckily, it was only cosmetic, but what a PIA, or rather, PIB (pain in bow).
