Backing down on a mooring ball or anchor to 2000-2500 rpms for 15-20 seconds helps ease my mind a bit. While that is probably standard practice for most on this board, I see many charterers pull up to a ball, slip their lines through the pendant, tie off, and then immediately jump in the dinghy and head to shore. I do see more people backing down while anchoring, but it is kind of inherent in the anchoring process and I think that most novice charterers go to extreme measures to avoid anchoring - at least in the BVIs. Backing down doesn't offer any guarantees, but at least it is a proactive step to make sure there isn't an impending failure with the ball or your anchor set.
