some guys dive off of private boats. and a lot of times they dive, leaving the boat unattended. I would highly recomend using two anchors tied about 45 degrees apart. depending on the bottom features, you need to follow at least one of them and tie it on. stories abound of divers returning to the anchor to only find a line in the sand pointing to their drifting boat. in a shallow water, one hour dive, a boat can drift VERY far.one could also argue to just not leave the boat unattended.
