Windy with rough surf, but not bad on the reef. Visibility was poor with lots of particles in the water, but I took my Mk ii and got some shots. Swam out to the blocks to descend. Couldn't see the bottom, but found the blocks once I got there. Then missed all the other landmarks in the bad visibility.
Ended up at the Perpendicular Rocks, where I got a shot of a juvenile Queen Angelfish.
After a couple of turns around the Knoll, I headed SW to the beach, where I fought my way through the surf and undertow to get on solid sand without wrecking my camera. Made it.
