Simplified Wreck Survey

Wreck details for the FPT IV, an underwater obstruction located off the coast of Selsey in the English Channel at coordinates 50 43.959 N, 0 53.842 W. The wreck site was most recently surveyed in October 2018. The vessel remains intact with a clearly distinguishable hull. The current structural dimensions of the FPT IV are 36.5 meters in length, 7.8 meters in width, and a height of 3.4 meters. The least depth measured by multibeam echosounder is 8.40 meters within a general surrounding water depth of 11 meters. The wreck is oriented on a 258/78 degree axis. Previous reports from 2013 suggested the wreck was buried, but the 2018 survey confirmed its presence at the current coordinates. Earlier survey history involved salvage attempts in 1989 and the removal of navigational marker buoys in 1990 after the site met required clearance standards.
