Raja Ampat's northern stretch forms its own distinct cruising and navigation zone, centred on Waigeo — the biggest of the area's four principal islands. Sailing here threads an intricate web of lesser islands, sheltered bays, and exposed channels, the Dampier Strait foremost among them. That strait is a deep passage dividing Waigeo from Batanta to its south, and it channels the Indonesian Throughflow like a funnel, generating the nutrient-laden, current-driven waters that power its extraordinarily diverse reefs.
Where a trip to Misool demands a long open-water haul across the Banda Sea, a phinisi charter up north stays within a relatively protected cluster of islands. Captain Yance Mambrasar, who has spent more than 25 years working these waters, notes that the run from Sorong to the Dampier Strait dive sites takes under six hours, putting your yacht (such as the 51-metre Dunia Baru) right in the thick of it by the opening afternoon.
