A high percentage of RNLI rescues involve people who get into trouble on beaches because they use unsuitable inflatables, don't inform themselves about tides, don't check the weather forecast, don't take sensible precautions when windsurfing or sailing, get stuck on cliffs, walk into the sea when drunk, try to commit suicide, etc. These days fishing vessels are bigger and better built so don't generally have difficulties in stormy weather, as they did in the past.
Would it be acceptable not to rescue these people because it was their own "fault"? I can't believe some of the comments on this thread.
The RNLI also gets called out when there is inland flooding. They are extremely well-trained and their expertise is valued throughout the world, which is why they host overseas rescue operatives and send RNLI staff overseas as advisers.
My family has been involved as volunteers with the RNLI for 200 years since it was first founded and still are - one of them was even honoured in the New Years Honours List. When there was more shipping around our coasts, many of the rescues were of foreign sailors and I have never read of any resentment that British volunteers were saving foreigners and I've read hundreds of articles and books about rescues.
People don't seem to understand the motivation of people who put their own lives on the line to help others - a life is a life as far as they are concerned.
PS. Vivian I know the RNLI is well run - that was the point I was making about why the RNLI prefers to remain a charity rather than be state funded and organised.
