Why do you think it brings out the worst in both motor and sail?

I believe it brings out the best of both.

Nothing wrong with a rock steady 8kt on any point of the compass. Most
times the main is just above idle and you can not hear. If the wind is
above 15 knots than I can make hull speed without main assist.

I know the alure of pure sail and the benifits of no prop drag. But
due to my current career and the high cost off communications I do not
have the luxary of unscheduled trips.
