Captain Calamity rescued yet again in his yacht named Mischief

Now the RNLI rescue service is becoming exasperated with the troublesome sailor.

Lifeboat crews say they have lost count of the times they have gone to his aid.

But 51-year-old Glenn says he is involved in extreme sports - and it is the public calling out the rescuers that is causing the problem.

On Wednesday the RNLI were alerted by the public after spotting his Hobie 16 catamaran capsize several times off Lusty Glaze beach in Newquay, Cornwall.

But the hapless sailor says there was no real danger.

Mr Gareth Horner, RNLI lifeboat operations manager at Newquay, said: "We have lost count of the times we have launched this chap and his boat.

"He was sailing in poor conditions at the limits of high water on a lee shore. This is asking for trouble.

"He got away with it by the skin of his teeth. He was very lucky.

"If they had come ashore 100 metres to either side of where they ended up - with the sea breaking against the cliffs and rocks - the outcome would probably have been very different."

Mischief has a long history with Newquay RNLI - in February 2006 she was rescued four times in four hours - twice by the lifeboat and twice by local fishing boats.

The lifeboat arrived at the latest rescue to find two sailors making their way to shore with the boat abandoned in the surf.

Newquay harbour master Derek Aunger said: "He was out in conditions that were far greater than he can handle.

"He thinks of it as a bit of fun and an extreme sport but he's exposing others to danger."

The RNLI estimates it costs £2,200 each time they launch a lifeboat.

Glenn Crawley said: "I was out with a friend when the mast failed and I found myself with a bit of a challenge.

"We beached the boat and put it to rest - the first I knew of the RNLI involvement was when the job was all done.

"Capsizing a catamaran is all part of performance sailing. Like any extreme sport there's an element of risk.

"The problem is that as soon as somebody decides on my behalf that I'm in danger, the RNLI are obliged to respond.

"If there isn't an emergency it would be nice of them to be honest enough to admit that."

He said the catamaran needed minor repairs after the latest incident.
