you recommend me to let the propeller turn og should I stop
it from turning, if I'm only concerned with the speed of the
sailboat - when only using the sails?


I guess I'm too long winded.

It is my guess that a freely turning propellor would produce
less drag than a locked propellor. This is assuming that
there is no load on thepropellor other than the friction of
the bearings that support the propellor shaft.
