YouTube Video: Sailor Explains What Caused the Fastnet ’79 Disaster

This YouTube video is a concise lesson in boat design, wave theory, heavy weather sailing, disaster survival, and so much more. It’s also one of the best explanations of the disadvantages of the IOR (International Offshore Rule) design boats. The IOR rating system was introduced in the sixties, and used until the early eighties. Many of the sailboats designed during those years were designed to maximize performance under the IOR rules.
