In 1645 the Portuguese still held Dibba but the Dutch, searching for potential sites for new commercial activities, sent the warship "Zeemeeuw" ('Seagull') to explore the Musandam peninsula between Khasab, on the Persian Gulf side, and Dibba on the east coast. Claes Speelman, the captain of the "Zeemeeuw", made drawings in his logbook, including what is certainly the earliest depiction of Dibba in a European source. Within a year or two the Portuguese were forced out of Dibba and held only Khasab and Muscat, which they finally lost in 1650.
