Pinnacle (Fathers #1) Dive Site
Site Overview
Pinnacle (Fathers #1), within the Fathers Reefs (between New Britain & New Ireland) of Papua New Guinea, is one of the region's most rewarding dive sites and a highlight of any Coral Triangle diving itinerary. A deep seamount where, in season, scalloped hammerheads school in the blue alongside silvertip sharks, dogtooth tuna, barracuda tornadoes, and massive gorgonians. Geographically the site features seamount and pinnacle and drop-off formations built from coral and rock substrate, dropping from a shallow top of around 12 metres to a maximum depth of about 45 metres, with an average working depth near 25 metres. Visibility is typically excellent, ranging from 15 to 35 metres, while water temperatures hold between 27 and 30 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Scalloped Hammerhead (Sphyrna lewini), Silvertip Shark (Carcharhinus albimarginatus), Dogtooth Tuna (Gymnosarda unicolor), Bigeye Trevally (Caranx sexfasciatus), Barracuda (Sphyraena barracuda), Grey Reef Shark (Carcharhinus amblyrhynchos), alongside dense reef fish, invertebrates, and the soft and hard corals that blanket the reef. The mix of nutrient-rich currents and Papua New Guinea's remote, well-protected reefs makes Pinnacle (Fathers #1) one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. Pinnacle (Fathers #1) is best enjoyed as part of a boat programme out of Kimbe, and it rewards wide-angle photographers, naturalists, and experienced drift divers alike. Papua New Guinea's strong community-based conservation ethos and remoteness help keep the reef pristine, so divers are asked to maintain exemplary buoyancy and respect the fragile marine environment at all times.
Dive Briefing
"Your dive at Pinnacle (Fathers #1) begins with a negative descent along the mooring line or wall, depending on the current on the day. You negative-enter in the current and drift around the seamount, watching the blue for hammerhead silhouettes, then ascend with a safety stop as the current eases. Plan to spend the deepest portion of the dive along the seamount between 12 and 25 metres, where the coral is most colourful and the larger fish congregate. Hook in on the seamount if the current is strong, and stay with your guide so the group ascends together. Mid-water, watch the blue beyond the wall for passing Scalloped Hammerhead (Sphyrna lewini) and other pelagics, and keep an eye on your no-decompression limits given the depths involved. Ascend slowly with a safety stop at five metres to off-gas safely. Because Pinnacle (Fathers #1) can experience strong currents and occasionally reduced visibility after heavy rain, dive with a surface marker buoy and always follow your operator's site-specific briefing and emergency plan."

Traveler Notes
Who is this for?
Pinnacle (Fathers #1) is aimed at advanced divers holding at least a Advanced Open Water certification, and it suits those comfortable managing strong conditions and maintaining neutral buoyancy along seamount terrain. Photographers, marine-life enthusiasts, and experienced divers will find it especially rewarding, while this is a serious blue-water dive for experienced divers, while Coral Gardens is the gentler alternative. Divers who prefer calm, shallow, zero-current conditions should choose one of Papua New Guinea's sheltered house reefs or lagoons instead, and anyone without the recommended certification should complete a check-out dive with a local operator first.
For Non-Divers
Non-divers can watch the seamount from the liveaboard while divers drift the blue.
