The gig was traditionally reserved as the captain’s or commanders’ boat and often referred to as the Captain’s Galley [1].

Captain’s galley: any colour except green and blue, at Captain’s discretion. […] The power and pulling boats of individual ships other than Flag officers’ barges and Captain’s galleys, should be uniform in appearance, although it is not compulsory for both categories to be alike.
