Saturday morning as we were getting ready for a courtesy ride to Yorktown, Susan asked me to listen to a new funny sound on the boat. We turned everything off and could hear a faint crackling sound that we thought was coming from the bilge. As we started to open up the floor boards the sound became more distinct, but couldn't pinpoint the source. We kept pulling up the cushions, opening up the access and storage compatments and just couldn't find the problem. Susan went up the the service department to ask for help, while I started to investigate if the sound was also comming from the dock or other boats. As I was laying on the dock for the boat next to me, Susan came back to say it was just snapping shrimp. It turns out the local Grass Shrimp feasting on the bottom of our boat are territorial and when another shrimp apporoaches they snap their claws to defend the spot. An hour later we'd put the covers and cushions back and were off to another adventure.
