Speak to Tim.
In 1990 the furthest thing from my mind was
scuba diving. Then a friend came along and said he had heard about this
club where you could go and have a try dive to see if you liked it. He
didn’t want to go on his own so would I go with him. Of course I said no
problem thinking it would all be a waste of time, but as soon as I got
the kit on and put my head under the water that was it, oh yes this is
for me. My friend never came again, he started flying lessons instead.
In 1991 I got my novice and by 1999 I was an advanced diver. You might
think that took a long time but back then we did things a lot slower,
and as anyone who knows me will tell you I never rush things.

Due to not enough sacrifices
to the weather god we only managed to get one day of diving. With
weather and sea sickness only 6 of us made it onto the UB1195 the German
U-boat that sank the James Egan Layne. The dive was amazing with the
wreck fairly intact and swarming in Pollock and housing 2 monster
congers. We'll be back to beat the weather and do the other wrecks.

Grey seal – Halichoerus grypus
There are three populations of grey seal each with a distinctive
reproductive season. The subspecies found around the UK coast is
H.g.atlanticus. The grey seals found around our coastline inhabit rocky
coasts and islands on the Atlantic side, also the North Sea coast down
to the wash and the Farne Islands.
In 1985, the world population was estimated to be about 125,000.The males are 210cm long and weigh 270kg; the females are smaller at 180cm and 140kg. The males are heavily spotted and are darker than the grey females. The nose is elongated and arched especially in the males, who frequently have scarred necks from where they have fought with each other to mate with the females The males reach maturity at about 6 years of age, but do not mate until they are 8-10 years old. The females have their first young at about 5 ½ years of age. Pups are born from October to December, with a peak in mid-November. The cow gives birth to one white pup - which is conspicuous on rocks, but this colouration was excellent camouflage when seals gave birth on ice.
At birth the pup will weigh about 33lbs, the pup is suckled for about three weeks and the mother’s milk is exceedingly rich and so after 3 weeks, the infant will weigh 110lb. It is then is deserted by its mother Over the next two weeks the pup loses its white coat and then takes to the sea.
Their diet consists of migratory and open-sea and deep sea fish (usually large specimens) and some invertebrates such as crabs and other shellfish. Seals suffer the same problems as desert animals in that they must conserve water – they cannot drink sea water as it is salty. They gain some water when they eat fish. Marine invertebrates are very salty, compared to fish, so the seal needs to burn fat to release energy in order to excrete the salt it has taken in. Thus seals get fat if they eat fish and thin if they eat marine invertebrates.
Seals possess other features to conserve water; they have very efficient kidneys and a profusion of passages inside the nose, which capture water lost through breathing.
Males can live to about 30 and females into their mid-40’s.
Wreck of the Month - The Rondo
A beautiful wreck in the Sound Of Mull. Sank in 1935 by accident when the anchor chain broke during a storm, allowing the Rondo to drift down the Sound until hitting a small island. There it sat balanced on top whilst recovery work removed most of the deck fittings. It eventually slipped down the rock face bow first to it current position with its bows at 50m with the rudder at 5m. The best way to tackle this dive is to drop to your target depth then do your dive by doing a very slow ascent criss-crossing up the wreck. If you do get any decompression stops or safety stops these can be carried out looking at the rudder which is covered in soft corals. Penetration is minimal but there are a couple of nice ‘tunnels’ to swim up. Watch out for the huge conger!!
