In Panama we had an LCM at our disposal. When we went outside the breakwater to go out for deep dives the water could get a little choppy. Those flat bottomed landing craft weren't very smooth riding. The students were in the cargo well while we gathered around on the wheel house deck. We used to open up cans of Ham and Lima Beans and eat them cold. We would let the nasty cold grease slither down our jowls. It never failed to evoke a couple of green faces and students heading to the rail to call "RALPF!!"
