Thanks for the advice. I read your post before heading out early Saturday but didn't have time to reply. When I got down to Cockenoe Island on Saturday afternoon, all the sailboats were anchored on the Westport side, and all the powerboats were in the lagoon, so I anchored up with the other sailboats. The bottom on that side (I think) is sand and rock. Holding was good enough that my boat was still there and hadn't dragged after 3 tide changes, a night of steady 10knt winds and really choppy 2ft seas. From shore she looked like a cork with a toothpick stuck in it bobbing every which way!! My wife asked why our boat was swaying more than the other boats out there, to which I replied those other boats were heavier. She was gripped by temporary boat envy.
