These are some pics of USS Honolulu while transiting on the surface. It shows the bow wake and after wake. I believe we were going ahead full at the time (forward speeds were ahead 1/3, ahead 2/3, ahead standard, ahead full, ahead flank - ahead full was about 50% reactor power I don't remember how fast that was on the surface but it was not as fast as underwater). The last picture was from my last return to port during the maneuvering watch (All stations manned for coming into port). We were returning to Pearl, and, as a gift for my retirement, I was able to be up in the sail during this evolution for my first, and only, time. Usually, I was in the Engine room supervising (or when I was on Providence I was topside with aft line handlers). I am guessing the sub was probably doing ahead 2/3 or standard. Note how the bow now sticks up from underneath the water as the ship slows. The aft end of the submarine also becomes more above water (probably because of less of a wake).
