Up until the last few years, I was an avid boater. It becomes a lifestyle and I admit that I really miss it. Although RVing is not inexpensive, boating has become very expensive, especially larger boats. Berthing fees, marina fuel costs, insurance, maintenance and repairs just got to be too much for me. My 5th wheel trailer has provided great family recreation and we will continue it but I often long for weekend outings on the water. Wish I could do both. Anyway, I don't think you are going to save money by owning a houseboat.
