Of all the various websites supplying weather information, I have always found yours to be the most accurate. I started using your site when I was the Training Officer for the local RNLI station and word spread like lightning around the various UK stations of how good yours is.

Theyr.com weather products represent an innovative step for the yachtsman to gain a much more detailed insight than previously possible into the weather conditions likely to be encountered en route." The TRANSAT is the first ocean race that has had a weather support service of the calibre provided by theyr.com.
