Rotting boats will be disposed of in an effort to clean up waterways around Truro.
The city’s harbour master said more boats had been abandoned because of the harsh economic climate.
Many of the boats moored along Malpas Road have clearly been left to rot. Mark Killingback, harbour master for the ports of Truro and Penryn said it was notoriously difficult to track down boat owners.
He said: “We have got two which are going through an abandonment procedure.
“It’s when they stop paying us and we can’t find them that we look into abandonment.
“Money is tight and boats are not cheap to run. If they are not tended and the moorings break they may find themselves in the navigable channel.”
The Durundal, which is moored near the Boscawen Park car park, is in a state of disrepair and has fallen sideways.
The harbour master said his staff were in discussions with the owners of the boat over what could be done.
Mr Killingback said the idea of owning a boat was often more attractive than the reality.
He said: “Everybody has a dream that they are going to turn a sow’s ear into a silk purse. The reality is that the price of materials and their labour means that after a while it becomes impossible for most people.”
The situation is complicated by the fact that boats can change hands easily and so boats are often not registered to current owners.
Mr Killingback said: “We get people for whom it’s been their pride and joy and they disappear or they might fall into ill health.”
