As a rule
these gullets are terrible boats built from substandard materials and are replaced rather than fixed. The vast majority are not even remotely seaworthy
and have a bad habit of flipping over in a stiff breeze even with no sails
Somewhere I have pictures of when I went to Turkey
... There was an entire row of these with masts and booms up, full rigging
going everywhere, but not a sail on any of the boats. When I spoke with the crew all of them said they didn't carry sails
since the boats were to unstable to handle the heeling motion.
In short, better to buy a 100' houseboat than one of these wrecks waiting to happen. And keeping up with all the wood... The 80' Gulets had two or three guys whose whole job was revarnishing the wood.
