three lifejackets, the one on the right moves away, that leaves Yamamoto with Fuddy close to him, and if that's her head, with the sun shining on her forehead, then she's not wearing that jacket properly. What that black blob is and the green 'thing' is open to interpretation, her dark trousers possibly, and and what might be yellow/green shoes. But for someone not propeerly supported by her jacket, those knees are a long way up out of the water.
Hey, maybe the black trousers belong to Yamamoto, and she's between his knees? Then the shoes would be his. I think I had better make that coffee now...
