Even though my focus is on fresh water sailors and much more on the 1750-1780 period, I keep running into questions about 1812 sailors hats. I’ve got a small quantity of images that show them off to different degrees, so here they are:
Another of Algiers. This was painted in 1818 by Nicolaas Baur, and is entitled “Anglo-Dutch fleet in the bay of Algiers as support for the ultimatum demanding the release of white slaves on August 26, 1816.” Although the sailors are small in the picture, you can see hat outlines and some colors.
Thames barges, 1805. This is an image from the Maritime Gallery (see http://www.themaritimegallery.co.uk/maritime-archive-1.php).
Rochester Castle, circa 1802. Perhaps a bit early for 1812, as far as fashions go. This is an image from the Maritime Gallery (see http://www.themaritimegallery.co.uk/prints-pre-1900-2.php).
The Brig Nancy Ann, 1809, from the Peabody Essex Museum (see http://www.pem.org/sites/archives/mpd/t0189.htm).
“A sailor heaving the lead”, colored etching by J. A. Atkinson, 1807. From A Pageant of the Sea: The MacPherson Collection of Maritime Prints and Drawings, by M. S. Robinson, London: Halton and Company, Ltd., 1950. p. 209.
