The choice in one paragraph
A vessel making 10 knots covers about 240 nautical miles in a day. Every route below is really a sum of those hours.

The Lengths
Cape Kri, Manta Sandy, Blue Magic, Sardine Reef and Mike's Point — the highest-density reef diving in the archipelago, all within an hour of each other. No long crossings, so almost every day is a diving day. What it cannot reach is the karst.
The week most first charters book. Everything above, plus the overnight run north to the limestone country — the viewpoints, the lagoons, and a village day. One passage night each way is the price.
Trades the north for the south: Boo Windows, Magic Mountain, Fiabacet and Daram. Better diving than the north and worse photographs. The southern run is four to six hours by speedboat or an overnight steam, in each direction.
The shortest route that reaches Misool AND Wayag without the week feeling like a delivery trip. Two of the eleven are passage days and one is deliberately unscheduled — that spare day is what makes the weather workable.
All of the above plus the long passage east to Cendrawasih Bay — a separate national park, and the one place in the region where whale sharks are resident rather than migratory. Nothing shorter reaches it.
A Worked Example
A private charter is never run to the minute — the crew moves the plan daily for tide and weather. This is the shape of it.
Day 1: Sorong Pulau Mansuar
Twenty minutes by road from Domine Eduard Osok to the harbour, and aboard by late morning. A gentle check dive off Mansuar in the afternoon while the crew settles you in. The marine park permit is registered before you sail.
Day 2: Mansuar Dampier Strait
Cape Kri and Sardine Reef, both worked on the tide rather than the clock — the strait runs hard and the dives are planned around slack. Kayaking in Kabui Bay between the limestone in the afternoon.
Day 3: Dampier Strait Wayag
You wake up inside the lagoons. Mount Pindito at first light for the view the whole archipelago is photographed from, Ridge Rock before lunch, and a bonfire at Secret Bay once the light goes.
Day 4: Wayag Aljui Bay
Wofoh at first light, then Pulau Yangaffo for the mangrove edges — shallow, sheltered and completely different water from the strait. The pearl farm in Aljui Bay in the afternoon, and a barbecue on a beach with nobody else on it.
Day 5: Aljui Bay Arborek & Friwen
Manta Sandy at slack water — a cleaning station on sand, so the mantas come to you rather than the other way round. Then Arborek: 197 people, community-run conservation, and pandan hats bought from the women who weave them.
Day 6: Friwen Pulau Mioskon
Pygmy seahorses on the fans and walking sharks on the sand after dark — Mioskon is a macro site, and the slowest, most deliberate diving of the week. Turtles, stingrays and schooling snapper in the shallows for anyone who would rather snorkel.
Day 7: Pulau Mioskon Sorong
The steam back runs through the night, so the last morning is breakfast alongside rather than a rush. Twenty minutes to the airport from the harbour.
Time Under Way
Sorong → Dampier Strait
50 NM · about 5 hours under way
Dampier Strait → Wayag
120 NM · about 12 hours — an overnight passage on most vessels
Wayag → Piaynemo
80 NM · about 8 hours
Piaynemo → Misool
150 NM · about 15 hours — the longest leg inside Raja Ampat
Misool → Cendrawasih Bay
A full day and night east, past the Bird's Head. The longest passage on any itinerary here, and the reason Cendrawasih needs fourteen nights rather than eleven.
What that means in practice
Roughly 400 NM one way to reach Misool via the north. A vessel making 10 knots covers 240 NM in a day, so distance — not the number of dive sites — is what sets your itinerary length.
When To Go
The long routes close before the short ones do. In June, July and August most vessels skip Misool entirely — a four-night Dampier charter still runs.
Questions
Seven, if you want more than the Dampier Strait. Four is a diving trip in one place and works well as that. Ten or eleven is what it takes to add Misool, and fourteen is the only length that reaches Cendrawasih Bay. The constraint is distance under way, not how many sites you want to dive.
Ten trades the north for the south — Misool instead of Wayag. Eleven reaches both, and keeps one day unscheduled. That spare day is worth more than it sounds: it is what lets the crew move the plan when the weather turns instead of cancelling something.
No. Cendrawasih Bay is roughly 600 km east of Raja Ampat, in a separate national park, and the passage there and back is most of a fourteen-night itinerary. Anything shorter would spend the trip steaming past the places you came for.
Yes, and it usually is. These are private charters — the route is a starting point, and the crew adjusts it daily for tide, weather and what you actually enjoyed. What cannot be changed is the distance between places.
October to April. Manta activity at Manta Sandy peaks December to March, visibility is best February to April, and June through August is the windiest stretch — most vessels skip Misool entirely then, and the long crossings are often not worth attempting.
The marine park permit — IDR 1,700,000 per international visitor, IDR 725,000 for Indonesian citizens, valid twelve months — plus your flights and any transfers. Everyone over 12 needs one, diver or not.

Most of the itineraries people ask for are a night or two short of what they actually want. We would rather say that at the enquiry stage than have you find out on day four, halfway to Misool.
