I guess the incident described second-hand below by Captain Arnold could happen anywhere at anchor. Scarey to think about, but at least the cruiser in question was not harmed.
There has been a HUGE debate about whether cruisers should have guns aboard raging on several of the other mailing lists. Incidents like this will certainly make one think!

An experienced cruiser who goes every year to the Exumas from Chesapeake, moored as he always does in Winyah Bay just south of Georgetown in the charted mooring area just before you turn into the Estherville Canal (or after if you’re going north) .
He was woken up at 4am by somebody trying to get on his boat. It was a fellow asking for a cigarette and without permission he clambered on board and approached the cabin hatch asking if he could look around. My friend had a .45 pistol. As the guy poked his head down through the hatch he hit his face hard with the gun then demanded the guy immediately back off and jump off the boat or he’d be shot. He did so – where another guy had a small boat a few yards away. Apparently he learned there had been a series of robberies on boats in the bay. This incident was in May this year.
We have to consider the unpalatable fact of poor economic times. Amateur Piracy might well become a current risk on the ICW – especially to those who like mooring overnight in lonely coves. Owners should have a weapon of some kind on board – though maybe not a gun, since a flare pistol might be equally effective. And should NEVER come out of the hatch since by staying inside the boat, you hold the stronger position if temporarily.
You might recall I had a similar experience of two guys being on my boat at night as I was docked at Deep Creek Lock. In that incident I think they were simply teenagers looking to steal something on deck – but who knows – they are certainly volatile situations which could easily go wrong.
I’m holed up in Mill Creek, VA, – an absolutely pristine beautiful creek with deep water and high bluffs with only a few splendid homes hiding behind trees. Meeting a friend tomorrow across the river at Reedville. No signs of pirates here as yet. 🙂
Best wishes
