Water temperature in Vobster Quay yesterday was still a reasonable 15 degrees, until you get below 15m (at which point it drops to 11c) and possibly even less below 20m. But we did not go that deep.
Instead Sam & I explored the aircraft fuselage on dive 1 and the Jacquin II boat wreck on dive 2. While exploring the wreck we were joined by a freediver who went into the cabin through the window and out through the hole in the roof. He didn’t stay long!
