The boat hull cleaner 1 has a telescoping handle 6, a buoyancy control means 7, and a cleaning portion such as a scrubbing brush 8. The buoyancy control means 7 can be filled with water or some other fluid to regulate its buoyancy. When the boat hull cleaner is in use the buoyancy control means 7 serves to encourage the scrubbing brush 8 against the hull 3 to facilitate cleaning of the hull 3.
