Site Overview

The Nordby Wreck is a fascinating piece of maritime history resting on the seafloor off Raiatea, representing the remains of a fifty-metre three-masted schooner that sank in 1900 and has been gradually transformed by marine life into an artificial reef of remarkable biological and historical interest. The wreck lies scattered across the sandy bottom at depths between eighteen and twenty-five metres, with the main hull structure, anchors, and cannons still recognisable despite more than a century of coral encrustation and biological colonisation that has softened the hard lines of the original vessel into organic curves covered in living reef organisms. Batfish are the most conspicuous residents of the wreck, their distinctive triangular bodies and curious nature making them frequent companions for divers exploring the site as they patrol the wreck structure with their characteristic slow deliberate swimming style. Lionfish have colonised the various overhangs and sheltered spaces created by the deteriorating hull, their spectacular feathered fins and venomous spines creating a beautiful but cautionary presence among the wreck's nooks and crannies. The wreck's extensive colonisation by marine organisms has created numerous micro-habitats that support an impressive diversity of small invertebrate species including nudibranchs, shrimp, and crabs that make excellent macro photography subjects for divers who take the time to search carefully. Frogfish of various colours inhabit the coral-encrusted cannons and anchors, their remarkable camouflage making them challenging but rewarding finds for patient observers exploring this unique underwater heritage site.

Dive Briefing

"Descend from the boat to the sandy bottom where the scattered remains of the Nordby Wreck materialise from the blue water as your eyes adjust to the underwater environment. Begin your exploration at the main hull section where the coral-encrusted ribs of the schooner create a dramatic framework for photography and observation. Batfish are typically encountered immediately, their distinctive shapes and curious behaviour making them excellent photographic subjects as they circle the wreck structure with apparent interest in the divers. Lionfish occupy the sheltered overhangs and darker recesses of the wreck, their spectacular fin displays providing some of the most photogenic subjects on the site. The anchors and cannons scattered around the wreck perimeter have been transformed by more than a century of coral growth into unrecognisable organic forms that illustrate the remarkable power of nature to reclaim human artefacts. Search carefully for frogfish on the coral-encrusted metal surfaces and for nudibranchs on the various sponge species growing on the wreck structure. The macro life on this wreck is extraordinary, with numerous shrimp species and small invertebrates inhabiting every available surface. Complete your dive by circling the full extent of the wreck site before ascending for your safety stop above the sandy bottom."
