Loch Ness Project's Search for Crusader
2000 - 2002


On September 29 1952 John Cobb
, the famous Brooklands racing hero, holder of many speed records,  died after his boat Crusader disintegrated after hitting a boat-wake during a world water speed record attempt on Loch Ness. He became the fastest man on water (206.89mph) though did not achieve the record since the accident occurred before he could complete a second run over the measured mile.



At the end of the measured mile Crusader nose-dived into the deep dark waters of Loch Ness. John Cobb's body was swiftly pulled from the water by his support team and the wreckage from crusader sank to depths of over 200m.


Smaller pieces of the boat, blown off by the crash, were found floating and taken away to be burned on the shore.


Later, a memorial cairn was built at the loch-side by the local people to the  memory of a "gallant gentleman".

The Loch Ness Project decided to search for Cobb's boat in 2001, since this year is to be the 50th year since the tragedy. Using photography, archive film and digital image analysis, Adrian Shine began to plot the probable location of the wreckage of Crusader.



Over a period of 18 months, working from his laboratory at the Loch Ness 2000 Exhibition Centre, and the Loch Ness Project research vessel "Deepscan", Adrian identified strong sonar contacts during night searches of the area.


Skipper, John Minshull and Adrian Shine spent many long nights sweeping the plotted line with sonar and mapping the site.



This year as they closed in on the wreck they were joined by Gary Richardson, manager of Loch Ness 2000 and by other  Loch  Ness Project members and volunteers including David Martin, Elaine Minshull and Maralyn Shine.



By June the Loch Ness Project was satisfied they had found the debris field.  At this point the American Academy of Applied Science, on expedition  at the loch,  announced an interest in finding the Cobb wreck during the last 2 days of their visit  and were to be assisted by Gordon Menzies, a resident, owner of Temple Pier and as a child witness of the record attempt.



Adrian Shine presented the Project's data to the Academy team. Bob Rines, calling from the U.S.A,   immediately offered the Loch Ness Project assistance from his Cabaco ROV and  pilot Joe Caba and pilot Mike Nicholson of Deep Sea Systems aboard the vessel Boy David (Skipper Ken and David Skea).



On Thursday the 4th July exmination of the sonar contacts began and on Friday 5th July Adrian navigated the ROV over the search line and at 3pm success was achieved. The remains of Crusader, stark, angular and twisted loomed out of the dark sitting quietly in 200m of water. There were feelings of  satisfaction on the completion of the technical quest but also a sense of awe with John Cobb's courage and his achievement.



Sonar and underwater camera's were supplied by Kongsberg Simrad in Aberdeen and installed aboard the Project's research  vessel  "Deepscan".
