Royal Charter (ship) by some passengers, though not confirmed, that the master, Captain Thomas Taylor, was advised to put into Holyhead harbour for shelter. He decided to continue on to Liverpool however. Off Point Lynas the "Royal Charter" tried to pick up the Liverpool pilot, but the wind had now risen to Storm force 10 on the Beaufort scale and the rapidly rising sea made this impossible. During the night of 25/26 October the wind rose to Hurricane force 12 on the Beaufort Scale in what became known as the "Royal Charter gale". As the wind rose its direction changed from E to
Fujita scale and the wind speeds associated with the damage listed aren't rigorously verified. The Enhanced Fujita Scale was formulated due to research which suggested that the wind speeds required to inflict damage by intense tornadoes on the Fujita scale are greatly overestimated. A process of expert elicitation with top engineers and meteorologists resulted in the EF scale wind speeds, however, these are biased to United States construction practices. The EF scale also improved damage parameter descriptions. The original scale as derived by Fujita was a theoretical 13-level scale (F0–F12) designed to smoothly connect the Beaufort scale and the Mach number scale.
