I was stationed on Oahu from 77 to 81. I did a lot of fishing, peackcock bass on the the crystal clear freshwater interior lakes, saltwater from boats and the reefs. Good times and good eating.
Quick story: My best friend and I went on the reef out near Kanehoe. Gilbert had done this growing up in Guam and warned me to watch the water level under me while on the reef for any big waves that come in. What that means is a big wave will draw more water away from the shore before it crashes. We both hooked decent fish and didn't pay attention. I got mine in close and happened to notice that we were missing about 4ft of water below us and looked up just in time to get knocked a$$ or tea kettle by a big wave. Rolled me all over the coral and rocks. When I got clear, I started looking for Gilbert, who was much smaller than me and couldn't find him. About that time, I saw one of his flip flops go floating by. I started worrying about what I was going to have to tell his wife and yelled his name a couple of times. I hear a groan coming coming from a crevice in the coral near me and found Gilbert all twistd up in there. Helped him out and, other than some bumps and a lot of scrapes, he was Ok. Then he got a big grin and holding up his catch, says "At least I didn't lose my fish!" I had lost mine.
