While the dive team was busy documenting sites KR10 and KR11 on the morning and afternoon of 14 January, the magnetometer team took advantage of the calm weather and sea conditions to run a survey along the outside of the entire Kenn Reefs system. The first area surveyed was along the outside fringe of the ‘foot and ankle’, with specific emphasis placed on detecting offshore components of known shipwreck sites (such as KR1, KR2 and KR4). Because sea conditions were calm, the team also ‘deployed’ Lee on a tow-board behind the magnetometer.
The tow-board (also known as a ‘Manta-board’) is a flat, hydrodynamic-shaped board with handles that is connected to a towing vessel with a length of line. The person using the tow-board grips the handles, is pulled through the water at low speed, and can visually search the seabed for shipwreck material. Most tow-boards are designed so that their users can turn, dive and ascend through the water column at will, simply by changing its orientation with the handles. Lee was positioned 10 metres behind the magnetometer in the hope he might be able to visually spot and identify any anomalies it detected.

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:

Since the early 1990s the Maritime Union of Australia (MUA) has held an annual commemoration for World Maritime Day (29 September) at the museum. The union members gather to remember fallen merchant sailors during wartime and the dangerous work of seafarers in the past and present. They march across the Pyrmont Bridge at Darling Harbour and lay wreaths at the two large anchors in front of the museum.
