BB,
I don't think so. The truth is the only thing that crane does is to allow bigger boats to be put on racks. Instead of having a slip, a big boat (let's say over 25,000#) can be put automatically on rack. That increases spaces. I bet that computer controlled crane is not cheap and don't expect lower fees for the moment.
About that rackominium idea, I really don't understand it either. There is a place that opened on Dania Beach with this concept about a few years back. You buy your space instead of renting it. The price was about 100K for a rack. Even if I am paying $300 a month for dry storage, I would have to pay about 30 years to cover for my investment. Considering most people buy bigger boats every 3 to 5 years, then the rack becomes too small so you have to sell. I used to go by that marina every weekend and for over a year, most of the racks were still empty. I have no idea how it is now, but I don't understand that business for small boats.
