Flush with the exhilaration of discovering site KR12 and the ship’s bell, the team set to work the following morning (16 January) to document finds. John, Jacqui, Pete, Renee, Lee and Jules entered the water and conducted a baseline offset survey of the site, followed by detailed recording of the cannons and anchors. Jules then took close-up photographs of each anchor and cannon while Lee carried out a photogrammetric survey of these and other features, including the rudder hardware found in association with the bell.

Finding ‘Hope’ with a magnetometer: Kenn Reefs expedition, days 6 and 7

One of the major goals of the Kenn Reefs expedition was to find Hope, the small cutter built from material salvaged from Bona Vista, and later lost during the rescue of the brig’s crew. According to historical accounts, two boats were sent from the rescuing vessel (the ship Asia) to Observatory Cay, where they recovered most of Bona Vista’s crew, the brig’s allocation of specie (gold and silver coin brought aboard Bona Vista for trading purposes), and brought them aboard Asia. A skeleton crew of thirteen and the personal belongings of all of the brig’s officers and men remained aboard Hope, as did unspecified salvaged goods valued at £1,000. However, as Asia got underway and took Hope under tow, tragedy struck:

While the magnetometer crew conducted its initial search west of Observatory Cay, a second team embarked upon a metal detector survey of the cay itself and searched for evidence of survivor camps associated with the wrecked vessels Bona Vista and Jenny Lind.

The Australian National Maritime Museum and Silentworld Foundation recently led an expedition to the Australian Coral Sea Territory to conduct an archaeological survey of historic shipwrecks lost at Kenn Reefs during the nineteenth century. The Kenn Reefs expedition is a continuation of an ongoing collaborative project between the museum and Silentworld Foundation that commenced in 2009 and led to the discovery that same year of the wreck of the colonial government schooner Mermaid (lost in 1829 on what is now known as Flora Reef). No less than eight vessels are known to have wrecked at Kenn Reefs between 1828 and 1884, and most grounded in relatively close proximity to one another on the largest of the southernmost reefs in the chain, as it was located within an oft-travelled shipping route, but poorly charted until the mid-nineteenth century.
