With my cell concerns sorted for now we found two nurse sharks under the stern by the props, hiding in the darkness. Sadly scared away by our presence. Perhaps the electronics in our CCR’s causes them some discomfort? Swimming idly along the stern ramp we kicked our way into the gargantuan well deck, devoid of anything except a lavatory, slap bang in the middle. Needless to say, my childish humour took over and I sat on it, making some grunts, much to the amusement of my buddy! With the giggles subsiding we finned over to the middle deck and were welcomed by the darkness, broken only through our two torches lighting the way ahead. Down alleyways, through machinery rooms and workshops we swam, along narrow passageways and through open watertight hatches. Some of the passageways were so narrow a proper fin kick was not possible, merely a wiggle of the toes, unless the inevitable was accepted and a grab and pull method was used for propulsion. A conventional up and down fin kick would have resulted in a silt out for our number three behind me, which would have been less than ideal for her!
