dockominium
n.— «One response has been the rise of the dockominium, an idea that started in Florida’s year-round boating environment. Marinas sell boat slips like real estate, assuring the owner perpetual ownership, tax write-offs for interest paid if the boat docked in the slip is used as a second home, and, the idea’s promoters say, a chance to cash in on the shortage.» —“Builders Put Squeeze on Boaters” by Iver Peterson in Manasquan, N.J.
