Henry Wallace Stuart Clark MBE (20 November 1926 – 8 May 2011) was a sailor, author and businessman from Northern Ireland.
Clark was educated at Shrewsbury School and served in the Royal Navy Volunteer Reserve in World War II.
Nearly thirty years later he was heavily involved in another major reconstruction journey, the Lord of the Isles Voyage, from Ireland to Scotland in Aileach, a wooden galley of the kind used in those waters in medieval times.
The journey in Wild Goose by his son Miles, travelled around North Cape, Norway, and then through Russian waterways to the Black Sea, and on through the Mediterranean back to Northern Ireland.
His last book, The Call of the Running Tide, an all-new work edited by Bruce Clark and Tara Mackie, looking back on his long sailing career, was launched on Rathlin Island on 7 July 2012.
