Those Dinghy Barracuda!
09 August 2007
Wow! Who needs coffee after an experience such as this morning's!
While reclining in the cockpit with our respective mugs of mud, Hal and I heard muffled cursing and not so muffled splashings over at the dinghy dock. Being rather unusual we decided to investigate and found one poor old cruiser dancing in his dinghy with a barracuda swimming around his feet!
How did such a thing happen?
As a fish head was also found in the dinghy along with the barracuda we are guessing the barracuda was chasing the fish and followed it right through the air and into the boat where dinner was then served!
