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
Beaufort scale winds in hurricanes would be 23 in the scale. Today, hurricane-force winds are sometimes described as Beaufort scale 12 through 16, very roughly related to the respective category speeds of the Saffir–Simpson hurricane scale, by which actual hurricanes are measured, where Category 1 is equivalent to Beaufort 12. However, the extended Beaufort numbers above 13 do not match the Saffir–Simpson scale. Category 1 tornadoes on the Fujita and TORRO scales also begin roughly at the end of level 12 of the Beaufort scale, but are independent scales – although the TORRO scale wind values are based on the 3/2 power
