Police officers are joining forces with the Coastguard to crack down on rogue motor boat owners following an increase in ‘reckless behaviour’ towards other water users.

Firemen, harbour masters and lifeboatmen will also join forces to gather evidence to prosecute the offenders.

A Maritime & Coastguard Agency (MCA) spokesman said: ‘The tide has turned against people who think they can act outside the law when on the water.’
