Even if I had the $$ I am not sure I wouldn’t go nuts living on a boat. Many are too small and seem restrictive.
I would probably go stir crazy.
I amanother not claustrophobic but I do need my space. We have owned our boat 14 yrs and we looked at a bunch before finding this one. I would crawl on board and immediately exit shaking my head no. Ours has tons of room on board. She is beamy. People who have never been on board are shocked at the room.
If I was gonna live on one it would be a double cabin motoryacht. They are like condos on the water.
