It was a change in the law that docked it. There is some loophole that they used to be able to get by on, but now the loophole is closed. They are trying to get Congress to change it so that they can sail again.
We stayed last 4th of July. There IS airconditioning and the breakfast was delicious. This is a very old boat, and the cabins are small. The bathrooms are miniscule. However, we LOVED the history! We had a great time, and would do it again.
