Yes we did check it to make sure we had a good hold. It seemed fine and we were okay from the time we got there early afternoon until around 3am. The storm wasn’t really bad, just enough to send some choppiness into the bay. I think the constant action of the boat up and down combined with grassy/sand mixed bottom was what caused us to come loose. It really sucked having to deal with that at 3am, very dark and raining and very close to other boats. Not a fun way to wake up in the middle of the night! As Glenn said above, Great Harbor might be a good option for you.
