Well, I got in and got down - but couldn't stay down until I filled my dry suit pocket with rocks. I didn't get below 4m on the whole dive - that was where the chalk reef was. There was also a current that made it all pretty tough and we finished with a long swim back to the centre of town, rather than our entry point. We got up to the walkway and took off our kit and Nick, who had been very good about my shortcomings, went off to get his car. As Wibble says, time underwater and the difficult dives add experience - I now know to go to Sheringham slightly overweighted, using my harness rather than integrated weights as I was feet light. But, all in all, not a bad first dive in the sea in the UK. The next one will be better.
