The new regulations came into force last month and are designed to make the area safer for swimmers, boaters and other water users.
Last year, a passenger on a jet ski nearly lost his leg in a collision with a speedboat.
And last month, a member of the Société Jersiaise Marine Biology Section, which regularly carries out research around the Island’s shoreline, warned that it was a matter of time before a swimmer was killed by a speeding boat.
In a statement, a spokesman for Jersey Coastguard explained what action they had taken against people flouting the new rules.
He also said that officers had issued warnings to craft users in bays elsewhere in the Island.
‘Since the introduction of the new five-knot speed limit zone in St Brelade’s Bay, Ports of Jersey has been maintaining periodic patrols of both the beach and the bay during busy periods.
This has involved proactively talking to both beach and leisure craft users to advise and educate them on the new zone and further encourage the safe use of Jersey’s coastline and waters,’ he said.
‘Action taken since the introduction of the limit has included letters of advice for jet skis speeding in the bay, a warning issued to a vessel for not adhering to the rules and a formal interview took place between the Harbour Master and owners of two vessels seen operating in an unsafe manner in the bay. In the same period, warnings have been issued with respect to speeding incidents in Portelet, St Catherine, St Aubin and Grouville Bay.’
In addition to the speed limit which is in force in St Brelade’s Bay, any craft operating within a harbour or within 200 metres of the shoreline must travel at less than five knots.
