Patrol workers say it will help to cut response times to major incidents.

More than 6,000 people a day use the Sennen Cove area during the busy summer tourist season and lifeguard patrols are at the beach every day.

But lifeguard staff say that, with so many people using the water, they need the jetski to make sure that they get to bathers in trouble in time.

The new equipment was bought by Penwith District Council.

It has also been partly sponsored by Lyn Walton, a regular visitor to Sennen, who contacted the council to say that she liked the cove so much that she wanted to help.
