I visited Anegada a few years ago in a boat with a 6' 11" keel. I mudded her briefly two times in a matter of a few minutes. If you know what you're doing it's probably not a problem. It was my first time there so I wasn't very familiar with the landmarks. I've been there since that time with shoal keel boats with no problem. I seriously doubt I'll ever make that trip again with a keel over 6ft - just not worth the stress.
