I looked up Gulet cruising and found a number of examples which use both sail and motor depending upon the harbour requirements.

Some cruises are expensive and others not to bad.

NO! Not for canvas. They are for flying the flags that it's 5 O'clock somewhere. LOL!

Roy nailed it. And they do haul canvas. 😊

I remember before the revolution there, having a one week holiday on a Gulet which had accomodation for 40 squeezed onto a 50+ foot boat.
These could be a modern version?

When you see masts this high then they are for sails to be raised even if this is only a token gesture, as was the case when we had our holiday.
