But DrL and I can drive a tractor/trailer.....
And those definitely can take on the characteristics of a sailing ship. Lots of "sail area" on high profile vehicles.
Actually I couldn't see owning a sail boat and not being qualified to use it. I once met the master of a 57 foot schooner. It was in Piraeus and the ship was owned by an Italian businessman. The master of the ship was a retired Sergeant Major from the British army. The crew was just him (George was his name) and a lady from then-Yugoslavia who was the maid and cook. He let me tour the ship. I loved it. They just sailed around and would pick up the owner or other guests here and there.
