My career in experimental aspects of ancient ship design and construction started in 1981 with the construction of the late Tim Severin's Sindbad Voyage. Following that my interests expanded to maritime archaeology and ethnography. Over the forty years I was involved in several reconstructions of ancient ships, including a Bronze Age Greek rowing/sailing galley, a double outrigger voyaging canoe, a 15th-century BCE Egyptian ship, a Bronze Age reed boat, a 9th-century sewn-plank boat and an ancient pre-Biblical 'Ark before Noah'. Currently I am involved in research into the materials, strength and flexibility of sewn boat structures and investigations into the 9th-century Phanom-Surin ship in Thailand.
