That's seriously nasty Ian, I wonder if the guys were going out to a shout, or just playing in the breakers.
It would be one thing getting out to a distressed vessel in those conditions, but how about getting the rescue completed?
If you read the comments below the pic, it was the mechanic and not the pilot that went out in that force 11 to a stranded trawler. Lots of cajones. Our Coast Guard goes out in like seas off the mouth of the Columbia River between Oregon & Washington on the Northwest coast of the US.

Its never too rough or bad, if the call comes they go, whether as many of the crew turn up as would do on a nice sunny afternoon is another thing !but generally you can count on six or seven of the hard nuts turning up no matter what. The wind can be ripping the roof off the boathouse but they still go.
We were caught in a very bad blow off Cape Town a few years ago - in a 45' raggie - and we called the Cape Town Harbourmaster to warn him we were out there. He said they would launch the lifeboat to come and tow us in. We said it would be impossible to attach a tow in these seas and he insisted it was their duty to try. Ten minutes later he called back and said it was too rough to launch the lifeboat!
So, for South Africa at least, there is a limit beyond which they will not launch. Our anenometer was pegged at 64 knots and they were reporting gusts of 100 knots (200kph) at the airport. Seas were huge. I don't know if they have a specific set of conditions at which they call it a day, or if it's up to the individual lifeboat skipper.
