Black-Sailed Traders: The Keels and Wherries of Norfolk and Suffolk (Paperback) (ISBN-13: 9781912271443)

D Day - June 6 1944

Roy Clark in command of tank landing craft, LCT 770, landed on the beach at Arromanches-les-Bains to discharge tanks and troops; he noticed in the dunes a yellow flower growing and said to himself "these grow in my native Norfolk and if I ever get out of this alive, I will do something for posterity" and that was the conception of the Norfolk Wherry Trust.

Between 1950 and 1960 he tracked down as many wherrymen as he could and accumulated as much information as he could gather about Norfolk Wherries and wrote the book "Black Sailed Traders".
