I was just told by a PL on facebook, that he & his crew leave the mainsail up partially, so the helmsman can see ahead of the ship. His claim is that it does not effect the ship's speed.
Is this true? Why is this true, if it is?
If the Galleon was designed to force teamwork, and communication with the helmsman, then why do Galleons get to sail at full speed without being at full sail?
