Is this a houseboat, power boat, sailboat? I've heard benchmarks of general maintenance for sailboats (even freshwater, ignoring the additional corrosive effects of salt air) that add up to several thousand dollars a year even when brand new (hull cleaning, paint, dockline replacements, the many many small parts that need to be replaced every few years to stay in seaworthy condition, etc). I'm curious how your experience compares.
