British Maritime Flags: Naval Flags Flown in Portsmouth Naval Base
Parsons discussed Portsmouth, which is where much of the UK Navy is serviced. Parsons presented an overview of British flags discussing the red, white, and blue types of ensigns. He also noted that the Royal Yacht Squadron can fly the white ensign. He also showed great red flag of the HMS Warrior 1860 Red Ensign.
Another flag of interest was the "UK Out of Order" flag which has red and white vertical stripes.
