Yes, it was worth it until the grandkids came along and tied up weekends. Then the boat sat and was eventually sold.
We kept pontoon boats on the water for years. There were open slips in a protected marina 15 minutes away. Removed in the winter, trailered home to clean the pontoons, back to the marina for pole building storage. We used it enough to want the slip: park vehicle, walk down, uncover boat, load up, untie and go. Much quicker than waiting in line at the public ramp for up to an hour on busy days. No storage worries, no boat ramp loading accidents, no government environmental inspections for transporting an invasive species. We did have wasps build their home on every dock we ever rented. Another boat had raccoon problems after they cleaned fish on their boat. Security can be an issue, a stranger can untie and joyride a boat with little effort.
We trailer a fiberglass boat now, the current water we use is dirty and we only get out 5-7x a year.
