Kendall McDonald, a former Fleet Street editor, has been diving (and writing about it) for more than 45 years. He has been DIVERs wreck expert since 1960.
What is everybody keeping from me  
Why dont I find a wreck under me when I use the Admiralty position for it on my set A wreck-diver told me I dont get on wrecks when I use positions given in dive books because authors alter them to keep the wrecks to themselves. Is this true John Robbins.

No, it is not true! If you dont find wrecks at the Admiralty print-out positions, you are probably using a GPS set that functions in minutes and decimals. The Admiralty gives positions in degrees, minutes and seconds which are correct to the nearest second - sometimes half-second.
So you should convert seconds to decimals of a minute by using a simple conversion table which the Hydrographic Office Wrecks Section (Admiralty Way, Taunton, Somerset TA1 2DN) will send you.
Then I hope you will find all these wrecks I have been keeping to myself.

Family affair  
On 1 September, 1895, the ironclad HMS Vanguard sank in the Irish Sea after being rammed by accident by HM Iron Duke in thick fog. Two of my wifes great-grandfathers were serving aboard Vanguard on that day and it is as a consequence of their meeting that my wife exists at all. Has anyone dived the wreck and are there any photos of her on the seabed Chris Thomas.

Yes, she has been dived. She is not a war grave, as all 300 men aboard were saved during the 59 minutes it took this 6000-tonner to sink. Her captain, Captain R Dawkins, was reprimanded and dismissed from the service, though in his defence it was said that he spent valuable time saving his crew when he should have been trying to save his ship.
Her present position is 53 12 46; 05 46 15W. The highest point of the wreck is 21m to her mast, which is on a bank to the north of the main wreckage. The 85m wreck is tilted to starboard in a big valley in the seabed, taking the depth to 35m.
If anyone has a picture of the wreck or something like a porthole from it, Mr Thomas would love to buy it as a piece of family history. I will pass on any offers.

Waratah lost or found  
Ive been reading a book by Clive Cussler called The Sea Hunters in which he lists the liner Waratah as discovered and surveyed by the American National Underwater and Marine Agency. Can this be right Alan Kendall.

Well, I dont think it can be, even though the book is the first non-fiction one that Cussler has written. Most of his other work concerns Dirk Pitt, his all-action hero, and his biggest best-seller was probably Raise the Titanic!
But raise the Waratah he has not. Nor does it seem that NUMA found her, let alone surveyed her, or so the wreck-hunters of South Africa tell me. Mind you, to be surveyed in NUMAs terms appears to be just seeing an echo-sounder or sonar trace!
The Waratah, a Blue Anchor liner of 8472 tonnes, was returning from Sydney, Australia to London on the return leg of her maiden voyage. She called at Durban on 25 July, 1909, sailed for Cape Town the next day, exchanged signals with another ship on the 27th, and was never seen again. Nor were any of the 211 people on board, of whom 119 were crew.
There was much talk at the time of the Waratahs difficulty in recovering when she rolled - one passenger is reported to have got off at Durban though he was booked through to London, claiming that the ship was unseaworthy due to its habit of hanging at the bottom of each roll. A violent gale was reported during her passage to Cape Town, but despite big searches no bodies or wreckage were recovered.
Emlyn Jones, the veteran South African diver who has been searching for the wreck for 20 years, is at the moment working on a new towed underwater video camera with which he hopes to take a look at a magnetic anomaly off the Transkei Wild Coast.
He thinks it might be the Waratah. He has had two tries at the site but says that the incredibly strong currents have made it impossible for divers to get nearer.

Cheerful outlook  
Can you give me any information on a ship called HMS Cheerful that sank in June, 1917, in Bressay Sound in the Shetlands Emlyn Hicks.

HMS Cheerful was a destroyer of 335 tonnes, one of the 30-knotters carrying 60 crew. She was one of those long slim jobs, over 60m long, built in 1897 by Hawthorn and completed in 1900. All C class boats of this type had three funnels, a turtleback bow and a big bridge.
Cheerful hit a mine on 30 June, 1917, and sank so swiftly that there were only 18 survivors. However, if you have been looking for her in Bressay Sound you are unlikely to find her. All the reports I have place her much further south off Helli Ness in the district of Cunninsburgh. Part of one of her lifeboats was brought up by a fishing boat in that area.
I have no knowledge of any diving on her, but it would be worth a call to the Hydrographic Offices Wreck Section to see if they have got her among the 60,000 wrecks on their computer.

A question of identity  
Is there any way to identify a U-boat without entering her if she is a war grave I was one of the team that found UC-47 off Flamborough Head. Shaun Carr.

In your case there was little doubt that she was UC-47. Her position, number of mine chutes and number and siting of torpedo tubes tells us that. But to be doubly certain you should find her number stamped on the propellers and on the external grease nipples on her hydroplanes (When the props were taken off for servicing, they were stamped to ensure that the same ones were put back on.)
Prop-stamping of German submarines of the 1914-18 war is very useful indeed in identifying remains, but although they were at first most meticulous about making sure the right propellers were on the right boat, towards the end of 1917 when spares and boats were in short supply the Flanders Flotilla was forced into make-do-and-mend. I know of one U-boat with one number on one prop and a different number on the other. In most cases the boats number was stamped at the base of one blade on the shank of the prop sleeve.

 The question we posed in the last Wrecks Q&A for Trevor Spiers about which shipping line had plates bearing a crest with the letters CSN Co seems to have intrigued a lot of wreck divers.
I have passed all the replies on to Trevor, who is deep in new research as a result. He now hopes to trace the name of the wreck off the Sussex coast from which he recovered the plate.
Some wreck-hunters suggested that CSN stood for Canadian Steam Navigation Company, others that it was the Cambrian Steam Navigation Company, and yet others that the first letter is wrong - that it was really a G which then made it General Steam Navigation Company.
One even suggested a name for the ship! Ill let you know the name when Trevor cracks it.
