At Tower 17, the wind was out of the Northeast at about 10 mph. The NOAA forecast was for 6 to 7 foot waves, but we had 2-3 foot waves on the beach. I had no problem at all getting out, even with the camera. Once past the breakers, it was hard work to swim in the chop, but just hard, not difficult and certainly not dangerous. I swam out past the swim buoy and descended close to the blocks. I couldn't see them until I got to the bottom, but spotted them nearby. Swam up the gunsight and to the Cigar Rock , but missed the Gray mid-way rock. Spotted the big rocks North of the cut-out coral head and turned North towards the Perpendicular Rocks and the Knoll. I was having a hard time staying calm. Lot of surge. Lot of current. I focused on my breathing and controlling my buoyancy. I had some trouble breathing down. I kept wanting to fill my lungs with every breath. Still not a bad dive. Eight minutes shy of two hours. Got some pictures. No turtles.
