When I purchased my houseboat a couple of months ago, I took possession of it at Aqua and saw the rental houseboats for sale. I was told the marinia wanted out of the business. They just did want to fool with it any more.
It appears there is an oppurtunity availble in that area.
I will have two rental boats in service soon in Pensacola. Web page under construction and to be posted at house boat magazine at that time.
