Abstract:		 Visual inspection dives completed to assess in-situ protection measures put in place following excavations between 2017-2019. Exploratory dives also conducted to investigate seabed anomalies around the site. This included a preliminary photogrammetry survey and video recording of the newly exposed rudder. The rudder was subsequently recorded in detail and reburied. Conservation of the Invincible's cut-water has entered phase two, using heated PEG solution. Discovery of the rudder off the stern (SE end) of the wreck site, which lead to photogrammetry survey and video recording. The exposed extent of the rudder is 11.6m long, 1.62m wide at the lower end and 0.65m at the head end (Figures 1). It is to be complete with all it’s identifiable features, such as pine sheathing over the hard wood timber structure; five iron pintles and iron strapping at the head end; emergency chain attached to a ring on the outer edge, which lies across the upper end of the rudder; and two pedant hole between 3 rd and 4 th and 4th and 5 th pintle. It also has a carved feature on the outer side of the rudder where aligns just below entry into the gundeck (Figure 1). The rudder was successfully recorded and reburied in September 2022 using geotextile sheets and ten tons of gravel sandbags. The first phase of the PEG treatment has finished on the Invincible's cut-water. When the PEG solution reached 40% the second phase of heat treatment began. The tank has been fully insulated and a heating system installed to heat the PEG solution (Figures 5 and 6). This will continue until the solution reaches 80%. A turned wooden bowl was found exposed outside the gun deck structure of the port side (Figure 7). The bowl is currently desalinating at Bournemouth University’s conservations facilities. Following desalination PEG treatment will start followed by freeze drying at York Archaeological trust.
