not sure, but is it because you don't want a "false full sail" that is
actually the result of apparent wind caused by motoring?

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?
