My very cool uncle who lived at the marina in a house boat. There were many house boats , and I remember what a very cool existence it seemed to be.
Today there are no marina's with house boats in Florida. Maybe I am wrong, it's possible. But I have searched the state. You can find house boat friendly places but they are not house boats that look like houses. They are the vacation rental boat/style. They call themselves house boats, but they all look the same and they do not look or feel like homes.
I found this and was impressed. Imagine the possibilities, if only the would stop zoning Marina's for more condo developement. That is what was happening up in Long Island NY with a house boat community.
