In December 2014 I dived Swansea Bridge three times.
The first was a highly enjoyable drift dive with Mick Todd and a group from Sydney. I did not want to take any risks with my camera and left it behind.
Mick and I followed that up with a dive under the bridge. We got in as Slack was ending. Mick blamed his Sydney group “Unfortunately we got in 20 minutes too late because of being hampered as usual by a bunch of Pommie immigrants. There’s not much we can do about that, we have got very slack immigration laws here unfortunately”
My third dive was a Social Dive with Snorkel Safari Swansea. Slack was expected to be very brief and so it proved with just 5 or 6 minutes of totally slack water.
