Another question inspired by a Dutch sailor. I caught on
to what he was doing, because I was not occupied with
anything else at the time. No one else on board did.

While motor sailing, close hauled, you trim your jib so that it is
slightly luffing?

Why would you do this?

To dump air faster. The curve of the sail and speed of wind across the
surface might be slower than the speed your motoring. Until the wind
is strong enough to stop the lufing it might cause drag.
