Qatar's annual pearl diving event, the 'Senyar', sees traditional dhow boats with pearl divers competing for a first prize of 400,000 Qatari riyals. The event aims to keep Qatar's heritage alive and showcases the serious business of pearl diving, with teams of up to five divers vying for the largest number of pearl oysters. The boats are skippered by experienced sailors who need a deft touch to put the dhow in the right place for the divers.
