Really nice video of U89 taken by Richard Knights in July 2016 from the Rosguill

Somewhat unusual photograph of the stern section of the Audacious showing the outlay of the rudders and screws, taken from above by Simon Kay.  Detail etc. added by present author.

Another couple of nice photos – this time of the WW1 U-boat, U89 in 60m – taken by Darren McDonagh

Deck Gun on U89

Conning Tower on U89

Some nice photos of the Justicia Bow taken by Darren McDonagh (for orientation, see shot line in first 2 photos)

Couple of nice shots of the Laurentic bow taken by underwater photographer, Cathy de Lara.

I’ll use the words of Irish Technical diver, Stewart Andrews, to tell the story : –

As it turned out, this ‘dark’ and unsettled (deep) season came to a thrilling end with some proper exploration off Donegal. The very best discovery was left until the last dive. A big thanks to “Rosguill” skipper Michael McVeigh and trip leader Rez Soheil with some advice from the deep exploration guru, Barry McGill.

There are only four WWI U-Boats (operational) sunk off the north coast of Ireland –

One is the very large, popular and photogenic U89 in 61 metres, complete with two deck guns.  

Another – U110 sunk the luxurious British liner RMS Amazon and has yet to be found.

Another – U45 which was sunk by HMS submarine D7 – again, yet to be found

That leaves UB124 – one of the Type UBIII Coastal Torpedo Attack Boats which was physically smaller than the others, (distinguished by having just one stern torpedo tube) and having taken over from UB64, finished the attack on the troop carrier RMS Justicia. At over 32,000 tons, the Justicia was the largest ship sunk by U Boat in WWI & the second largest vessel afloat in the world at the time of her sinking
Having sunk Justicia, she herself was destroyed by depth charges on 20 July 1918. This was the only ship she ever sunk.
A very exciting dive indeed!  I hope to talk more about this at TekDive15 in Antwerp in November – in the meantime, here are just two images. The conning tower has been separated from the wreck as a result of the depth charges. The other image shows the single stern torpedo tube with the outer hull missing around the tube.

Visibility in mid – August has been a lot less than expected for what is usually one of the best months of the season.  Averaging just 10m where 20 to 25 should be the norm.  Coupled with very late plankton which is shutting down a lot of ambient light.

However, diving goes on with the “dealable” 10m vis and Rosguill found a new wreck last year in 97m and dived it recently to find a very nice Type IX Operation Deadlight WW2 German Uboat.

Snorkel head shown with exhaust outlet on left hand side -radar absorbing material (Alberich) and ball float covering the air intake on right hand side. There is also a small bracket to hold the radar detection unit. For scale the snorkel float is approximately the size of a football.

Sitting just aft to the conning tower are the surface running engine intake and exhaust manifolds – periscope shown above and behind.

After a slow start surface water temperature is now normal – 14 degrees in mid-July.

Vis on the classics has varied from 10m to 20m with a usual 15m

Ambient light has been a little lower than normal for this time of year – plankton bloom late and hence heavier than normal.

Weather has been mixed the whole season so far and remains unsettled looking forward.  It has been many years since we had such poor weather in May & June and we had a storm mid-July which I have never seen here (June – yes, but never July or August).

The iconic bow of the Justicia, some signs of collapse.

Shot – Spot

Surface water temperature this year has been stubbornly low and last day in May has not yet reached 11 degrees.

Visibility start May was 8m or so but 30 May on Justicia was a respectable 13m

After a couple of really nice weeks weather around Easter the weather has been very unsettled.  5 – 10 day range forecast is optimistic.

Nice photo of one of the screws, not often dived at the stern, on RMS Justicia (70m), taken by Stewie Andrews, 30 May 15.

Marvellous YouTube video produced & filmed by the great Norman Woods showcasing some of the classic north Donegal wrecks…

Second week in September 2014 with unusually calm weather and the vis is maximum 12 metres – 7 metres on the Audacious 12th September.

Inexplicable and unbelievable.

These videos having been accessed appear to be a type 11D and a Type 1XC/40.

Vis has been in the 20m range lately. One particular day 30m vis was reported on HMS Audacious with impressive ambient light.

Surface water temperature around 16.5 degrees.

After an extremely settled period from start May to end July, the weather has become unsettled. Fingers crossed!!!

Weather, water temperature & visibility really cannot be beaten at this moment off north Donegal. Calm seas, 16 + degrees Centigrade & 20m+ vis.

Below is a very nice photograph from a couple weeks ago of the bow of HMS Hurst Castle – taken close to the bow fairlead and also showing the ship’s anchor still in the hawsehole.

Also 2 photographs from differing angles of the “Squid launcher” on HMS Hurst Castle. The Squid launcher was the latest technology during WW2 which allowed anti-submarine charges to be delivered forward of the surface vessel at a depth determined by the “ASDIC”. This system dropped the squids in a triangle pattern which may be ascertained by the 2 slightly offset tubes.

Very nice photograph of the 88mm gun on the deck of U 89, rammed by a HMS Roxburgh and lost with all 44 men.

In 60m, this is an absolutely fantastic dive.

Surface water temperature now extremely high for this time of year at over 15 degrees C.

Visibility after being great was at 8 and 10m on couple days at HMS Audacious. However, reports of other sites are of very good visibility.

Vis around 15 – 18m off north Donegal at the moment. Water temperature around 12.4 centigrade.

Plankton seems to be only starting now – very late or very little?

Couple of nice photographs from Stewart Andrews (copyright) of one of the 4.7 inch guns on HMS Viknor and another of the bow of HMS Pinto.

In 60m this WW1 U boat is a super dive.

Video by diver on the Rosguill.

15 metres plus on a wreck out west 3 May.

Good start to the season

4 May – Justicia – 18m & lots of ambient light. Cold though! Surface 10.5 C.
