I can speak for two marinas [one with a grass beach] in my area that have mast up dry storage with access to a close ramp for about $50 month. I have a wide beam cat and this enables me to put the boat together and either leave it on the trailer or beach. The other lake has a rock shore and no beach around the entire shore but its 12 miles from my house as well as being a constant level lake. Several cats sail out of there but I like the grass beach for cats. Both marinas have full locker rooms with showers, restaurants [one with live entertainment on weekends], security and fences with locked gates, well maintained etc. Dogs and kids rule at both marinas. The yacht clubs are at least double almost triple for the same service.
