Gotcha. Certainly spooky for the MOB and the thing that'll keep a skipper awake at night.
Was the MOB from your vessel?
Yes, an absolute idiot, previously warned started washing windows around the outside without a watcher... wearing Crocs... New owner had never pulled an anchor before so I stepped back to give him a pointer or two and saw the swimmer trying desperately to get on the boat... and failing.
Had I not made that step back no one would have known for a long time...
