The Spithead Review
In June 2005 Challenge was invited to attend The International Fleet Review by Her Majesty the Queen at Spithead. This was quite an eventful time as after Challenge had dropped her anchor at the precise spot the the Admiralty had assigned for her she developed a leak in the steam pipe for the windlass. this meant that the anchor could not be raised other than by hand. Fortunately Bob Adam, (chief engineer) managed to remove the leaking pipe and get one made ashore, refitting it just before the anchor had to be raised again thus saving the day
The International Festival of the Sea, 2005 was a festival held at H.M. Naval Base, Portsmouth between the 30 June and 3 July 2005. It was the fifth in a series of International Festivals of the Sea held in the United Kingdom since 1996, and was also the final part to the long week of festivities that began with the International Fleet Review 2005 off Spithead, Portsmouth on 28 June 2005. The event allowed people to walk around the Naval Base, to go on board all of the visiting vessels, including several vessels belonging to the Royal Navy and also for visitors to walk through the large sheds of the VT Shipbuilding group on site and see the parts of the Type 45 destroyers, HMS Dauntless and HMS Daring being constructed there.
