Kenneth Lewis, of High Street, appeared before Corby magistrates on October 17 when he was fined £1,000 and ordered to pay £230 and £308 compensation to cover the unpaid charge.
All boats kept, let for hire or used on Environment Agency waterways must be registered.
Registration discs and numbers must be clearly visible to the authority’s enforcement staff.
It is the owner’s responsibility to inform the Environment Agency in writing of a change in ownership of the boat.
Irven Forbes, Waterways Manager, said: “Failing to register a boat just does not pay – not only do people risk being prosecuted and fined up, but they still have to pay their registration charge and will end up with a criminal record.”
For advice on how to register a boat, contact the Environment Agency’s Boat Registration Team on 03708 506 506.
