Although the idea of the anchor to bouy and lazy line is a good one, for me it's a compromise, albeit a small one. I keep the boat running to ensure there's no chance of engine starting problems in case of an emergency pick up...
Keeping mobile also allows you to just stand off the bouy, keeping watch for traffic, enebling you to put yaurself between divers/bouy and any craft that ingnore your A flag as well as help position the RHIB if it's a bit choppy... |
Horses for courses; it's common practice to anchor here - down this part of the world, we rarely have big tidal streams and our population density is so low so that even in the popular areas, we rarely see other boats, particularly close inshore to the cliffs where we do 80% of our dives.
This is today's tidal prediction for Hobart:

We rarely get much more than a metre difference between successive high & low water, so in some ways, it's like being in a lake in many places, currents are very modest.
