The Royal Welsh Yacht Club was formed in Caernarfon in 1847 by local solicitor Llewellyn Turner, William Knight (Rear-Commodore of Royal Harwich Yacht Club), Lord George Douglas-Pennant and other prominent locals.
Sailing regattas had been held in the town in 1829 and 1846 and were subsequently organised regularly by the club.
On 5 May the same year it was also awarded the warrant to fly the defaced blue ensign and three days later Queen Adelaide, bestowed her royal patronage upon the club.
[1] In 1854 the Club took the 13th century Porth-yr-Aur, formerly the town's west gate or watergate, built c.1284, as its clubhouse.
[6] Club members have achieved a number of seafaring accomplishments, including major ocean crossings and circumnavigations of the world.
