Portsmouth worked well today as the venue for an Underwater Navigation dive to kick off the Advanced Open Water syllabus for Dianne. Her skills were impressive. The visibility of some 40-50 feet really helped, allowing the legs on the triangular and rectangular navigation swims to be significantly larger than usual.
Chris was a great help, providing another set of experienced eyes in the water and towing the dive float. It's a great sign of approaching Summer that the Coastguard vessel, Cape Hearne, has returned to the harbour. The only negative in any of the diving recently continues to be the chilly, in-water temperature. Today's minimum was shown as 32F (0C). The air temperature of 4C (39F) wasn't anything to write home about, but the Sun was shining brightly, if intermittently.
