A comprehensive picture of the life and responsibilities of an English medieval shipmaster. Despite a background of war, piracy, depopulation, bullion shortages, adverse political decisions, legal uncertainties and deteriorating weather conditions, between the mid-fourteenth and the mid-fifteenth centuries the English merchant shipping industry thrived. New markets were developed, voyages became longer, ships and cargoes increased in size and value, and an interest in ship ownership as an investment spread throughout the community. Using a rich range of examples drawn from court and parliamentary records, contemporary literature and the codifications of maritime law, this book illuminates the evolving management and commercial practices which developed to regulate the relationships between shipowners, shipmasters, crews and shipping merchants. It also brings to life ship performance, navigation, seamanship, and the frequently harsh conditions on board.
