Three boat owners prosecuted on the Broads in February
The Broads Authority is hoping the cases will act as a deterrent to other boat owners
Three boat owners have been ordered to pay a total of more than £4,000 for offences on the Broads.
Great Yarmouth Magistrates' Court ordered Mr Drew, of Harleston, to pay a £1,000 fine, as well as £500 in costs and a £100 victim surcharge.
He was convicted of three counts of failing to navigate with care and caution, and breaking the speed limit on the Norfolk and Suffolk Broads.
On the same day another boat owner was fined £800 and ordered to pay £464 in costs and an £80 victim surcharge.
Mr Colman, of Bradwell, was convicted to navigate with care and caution, as well as speeding.
Earlier in the month on 3 February, Mr Walker of Upton appeared before Norwich Magistrates' Court was convicted for navigating without care and caution, with unacceptable manoevres and excess speed.
He was also convicted for failure to obey/conform with lawful direction and was fine £650 and order to pay costs of £400 and a victim surcharge of £65.
Senior Ranger for Compliance and Safety, Jon Hopes, said: "Preparing a prosecution file for a hearing at criminal court is time consuming and takes Rangers away from their other duties.
"We want to raise awareness to river users of the importance of keeping to speed limits, and navigating with care and attention. These cases should be a deterrent to others.
"Maintaining the 126 miles of navigational waters is expensive, and all the money raised from our boat owners’ tolls is spent on maintenance, dredging and navigational improvements."
The Broads Authority is asking people who witness boats speeding or being controlled dangerously to report it on 01603 or Broads.Control@broads-authority.gov.uk.
