This video is not for the faint of heart, but it is a dramatic testimony to the courage and dedication of the crew of a RNLI (Royal National Lifeboat Institution) rescue boat who went out in 45-mph winds and 30-foot waves to rescue six fishermen on a disabled fishing boat off the north coast of Scotland.
The fishing boat became disabled when it fouled its prop in a westerly gale, and it started drifting toward shore. It took the RNLI rescue boat more than nine hours to tow the fishing boat back to port; the tow line parted a total of five times.
