COASTGUARDS warned today they will prosecute rogue jet skiers and other water users who put lives at risk off the Dorset coast.

Patrols will continue throughout the summer at hot spots to ensure people are behaving in a safe manner.

Portland Coastguard district operations manager Mark Rodaway said he was pleased that most personal watercraft users behaved responsibly.

But he urged people who have not yet done so to join a club and get the proper training before heading out to sea.

Last week jet skier Mark Goodwin was jailed for six months after a collision at Bowleaze Cove in which fellow rider Paul Facer sustained horrific injuries.

The case made legal history after a judge classified a jet ski as a boat for the first time, allowing the prosecution to proceed with the charge.

Mr Rodaway said: "Vessels that are hired out could be considered commercial craft and that is something the Maritime and Coastguard Agency can regulate against, ensuring minimum safety standards are met.

"The MCA is working with the industry and the Government studying these issues in light of the court's rulings."

Mr Rodaway said there was an increase in all maritime activities including jet ski use because of people having more disposable income and leisure time, coupled with the fact that travellers are reluctant to go abroad because of the current international climate.

Portland Coastguard is working with Dorset Police's marine section, harbourmasters and local councils to ensure the waters remain safe.

Mr Rodaway added: "We have always gone down the education route with regard to personal watercraft safety and we will continue to do that where we can.

"However, there are rogue elements who can present a danger to themselves and others.

"If they do not listen to safety advice and do not conduct themselves in a safe manner then we will be going after them and if necessary taking them to court."

Users of jet skis and speedboats are being reminded to observe speed limits, operate their craft in designated areas and look out for swimmers and divers.

They should also consider the effects of noise pollution and the wake of their vessels, as well as staying away from marine mammals such as seals.
