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.
