A Raja Ampat dive boat is designed around three problems: current, distance and turnaround. Sites in the Dampier Strait run hard on tide, the good reefs are spread across long open crossings, and a dive centre only makes money if it can put divers in the water three times a day without exhausting them. Our new-build dive vessels are typically 12–20 m with a compressor room, proper tank handling and a hull that holds station in current. Indicative budgets run USD 150,000–450,000. Construction contracts are issued by PT Komodo Galangan Nusantara.
Hull behaviour comes first
Most dive-boat disappointments are hull problems wearing a deck-layout disguise. Three characteristics matter more than anything else here:
- Station-keeping in current. Pick-ups at Cape Kri or Blue Magic frequently happen with two to four knots running. A hull with enough directional stability, adequate rudder authority and predictable low-speed handling makes that routine. A hull without it makes it dangerous.
- Sea-keeping on the crossing. Enough freeboard and a bow that parts a short chop rather than slamming through it. Divers who arrive soaked and bruised do not dive well.
- Manageable draft. Deep enough to track, shallow enough to work reef edges and beach landings safely.
Getting all three at once is a design exercise, not a catalogue choice. It is the reason we start from your actual dive sites and schedule rather than from a length.
Compressor room and air supply
The compressor installation determines both the operating tempo and the guest experience. Key design decisions:
- Segregation. Compressors and their intakes belong in a dedicated, ventilated space away from cabins, exhaust outlets and generator uptakes. Intake placement is a safety issue, not a convenience one.
- Capacity with margin. Size the compressor set to refill the full cylinder complement between dives with time to spare, then add redundancy. A single compressor is a single point of failure that cancels an afternoon.
- Access for maintenance. Filters, belts and separators need to be reachable without dismantling the boat. If servicing is awkward, it will be skipped.
- Noise and vibration. Isolate mounts, line the space, and route ducting so guests seated aft are not sitting on a drum.
Nitrox membrane systems, banked storage and oxygen handling are specified together — the detail sits in oxygen systems and safety for new-build dive boats.
Deck layout and diver flow
A good dive deck moves each cylinder once. Racks are positioned so a diver kits up where the tank already sits, steps directly to the entry point, and returns to a rinse and de-kit area that does not block the next wave. Camera handling gets its own table with padded surface, individual charging outlets and a dedicated freshwater rinse — mixing camera rinse with mask and fin rinse is how expensive housings get flooded.
Boarding is the other place designs fail. Ladders must be wide, deeply immersed and usable in a swell with fins on; a second ladder is worth the cost on any boat carrying more than twelve divers. The full treatment is in designing the ideal dive deck and deck material choice in hull and deck material comparison.
Safety systems
Raja Ampat is remote. Evacuation is measured in hours, not minutes, and the nearest recompression facility is a serious journey away. That reality should shape the specification:
- Emergency oxygen sized for a realistic evacuation window, stowed accessibly and secured for a seaway.
- Redundant communications — VHF plus satellite messaging — because mobile coverage is unreliable across most of the archipelago.
- A dedicated casualty space where a diver can lie flat under shade, not the saloon floor between guest bags.
- Surface marker and recall procedures designed into the boat: a working horn, a proper lookout position, and a tender or chase boat where drift diving is routine.
Dive support and expedition vessels
Beyond day boats, we build larger dive support vessels for expedition, research and film work — hulls with extended range, deck space for compressors and rebreather support, workshop area and accommodation for a technical team. These overlap with the liveaboard programme; see custom liveaboard new-builds.
Budget and schedule
A 14–16 m day dive boat typically runs 6–10 months from contract to handover; a 20 m dive support vessel with more complex systems runs longer. Machinery, compressor plant and finish level drive the budget more than length does. Line-item drivers are on the pricing page, and the machinery framework in technical specifications.

Frequently Asked Questions
How should oxygen storage and compressor rooms be laid out on a new dive boat?
Compressors and oxygen storage belong in segregated, well-ventilated spaces with intakes placed clear of engine and generator exhausts. Both need maintenance access without dismantling surrounding structure, secure mounting for a seaway, and noise isolation so guest areas are not affected. Emergency oxygen is stowed separately and kept immediately accessible.
What deck features are important for underwater photographers?
A dedicated camera table with a padded surface, individual charging outlets, secure stowage for housings and a freshwater rinse tank used only for cameras. Wide, uncluttered deck space and a stable platform for handing gear in and out of the water matter just as much as the table itself.
What makes a hull suitable for diving in strong Raja Ampat currents?
Directional stability and rudder authority at low speed, so the boat can hold a line while collecting divers in two to four knots of current. Add enough freeboard and a bow shape that handles a short steep chop on the crossings, and a draft that tracks well without preventing reef-edge and beach work.
How long does a day dive boat take to build?
A 14 to 16 m day dive boat typically takes six to ten months from contract signature to handover, depending on material, machinery lead times and specification level. Larger dive support vessels with complex systems take longer.
