Dive Site: Rhun Drift

About Rhun Drift

Rhun Drift is a captivating dive site situated within the Banda Sea, an area renowned for its pristine marine biodiversity and geological uniqueness. This remote region, often referred to as the 'Spice Islands,' benefits from deep-water upwellings and volcanic activity, creating a vibrant ecosystem that supports an extraordinary density of marine life. Divers here experience dramatic underwater landscapes, from steep drop-offs to expansive coral formations, all fed by the rich currents of the Coral Triangle. The topography of Rhun Drift is characterized by dynamic currents that sculpt its reefs and attract large pelagic species. While specific depths for Rhun Drift are not detailed, Banda Sea sites typically feature steep cliffs and seamounts rising from the deep, with active depths ranging from shallow reefs to over 30 meters. The unique environment fosters both soft and hard coral gardens, teeming with reef fish and attracting larger predators. The marine life at Rhun Drift, and throughout the Banda Sea, is influenced by seasonal upwellings, particularly from September to November, which bring cooler, nutrient-rich waters to the surface. This period is prime for observing massive schools of fish, including barracuda and trevally, and offers increased chances for encounters with hammerhead sharks. The site offers a true blue water diving experience, providing a glimpse into an untouched underwater world. Diving at Rhun Drift is typically a drift dive, where the current dictates the pace and direction. Liveaboards are the primary way to access this remote site, ensuring divers are well-briefed on entry and exit procedures adapted to the current conditions. The experience emphasizes going with the flow, making it a relatively effortless way to cover extensive reef areas and observe the prolific marine ecosystem.

Conditions & Currents

Rhun Drift is a quintessential drift dive, meaning currents play a significant role in the dive experience. Currents in the Banda Sea can be strong, especially during peak seasons driven by the Australian-Asian monsoon system, which results in intense upwellings. Divers will typically enter the water and allow the current to carry them along the reef, rather than swimming against it, making it a less physically demanding dive once neutrally buoyant. Visibility is generally excellent, often exceeding 30 to 40 meters during the prime diving months. Due to the nature of drift diving, negative entries are not always necessary, but swift and efficient entry and exit procedures are important, with the liveaboard following divers and picking them up at their surfacing point. The boat crew tracks divers by bubbles or a deployed surface marker buoy, ensuring safety and ease of retrieval.

Dive profile & how the dive runs

Diving at Rhun Drift typically begins with a live boat entry, where divers enter the water as the vessel drifts along the reef. Upon descent, divers maintain neutral buoyancy and allow the current to carry them, minimizing effort. The dive route often follows the contours of the reef or seamount, moving through various depth bands to explore different marine habitats. Dive depths can vary, but most action-packed pelagic encounters occur between 15 and 30 meters where thermoclines often aggregate schooling hammerheads and other large fish. The dive concludes with a safety stop, during which a Delayed Surface Marker Buoy (DSMB) is deployed to signal the liveaboard for pickup. The boat crew will then maneuver to the divers' exact surfacing point, ensuring a comfortable and safe exit.

Underwater photography

Capturing the vibrant marine life and dramatic topography of Rhun Drift requires adaptability due to the drift conditions. Wide-angle lenses are ideal for showcasing the vast schools of barracuda, trevally, and batfish, as well as the potential for schooling hammerheads against the blue water. External strobes are highly recommended to bring out the true colors of the corals and fish in deeper areas or against the backdrop of the open ocean. For macro opportunities, a good focus light and patience in the current are key. Buoyancy control is paramount to avoid contact with the reef while navigating the drift and to secure steady shots. Always be mindful of your surroundings and the current when composing your shots, and prioritize safety over capturing the perfect image.

Getting there & logistics

Access to Rhun Drift in the Banda Sea is primarily via liveaboard trips, often departing from Ambon. International flights typically land in Jakarta or Bali, followed by domestic connections to Ambon. These liveaboard itineraries offer comprehensive exploration of the Banda Sea and sometimes extend into the Forgotten Islands, with durations ranging from 7 to 14 days. The remote nature of the region means that liveaboards provide all necessary amenities and logistical support, including dive guides, equipment, and meals. While specific permit fees for Rhun Drift are usually included in liveaboard packages, divers should confirm this with their operator. Some trips might involve flying out from a different airport, such as Saumlaki, depending on the itinerary's range.

Safety & environment

Diving at Rhun Drift, like other remote Banda Sea sites, necessitates strict adherence to safety protocols. Given its isolation, the nearest recompression chamber is not immediately accessible, making robust dive accident insurance essential for all divers. Evacuation can be complex and time-consuming, reinforcing the importance of safe diving practices and conservative dive profiles. Divers must maintain excellent buoyancy control, particularly during drift dives, to avoid uncontrolled ascents or descents and to prevent contact with the reef. Staying close to your buddy and following the dive guide's instructions on current behavior and boat pick-up procedures are crucial. Always deploy a Delayed Surface Marker Buoy (DSMB) during your safety stop to ensure the liveaboard crew can easily locate you in the open water.
