That is what I do. It is better to have a load on a diesel even when idling.
When I set the anchor overnight, I reverse at full throttle in order to set
it properly, so mine are usually dug in pretty good. Once in a while, she
will set really deep, but never so deep that the windlass can't pull it out.
The windlass will work on the chain rode if you keep it tight, but it is
rough on the chrome. A simple solution to protect the finish without a
conversion to a rope/chain gypsy is to secure an old piece of halyard
between the anchor shackle and the rope rode shackle. When you get to the
chain, take it off the windlass and take a couple of wraps of the halyard on
the drum and haul her on in.

If the engine is running, I feel that good seamanship requires me to keep a
good watch so I sit in the cockpit, usually partaking of a beverage of some
sort and enjoy the view.
