I think you need to be either 24.564m from the left or 35.321m from the right, depending on the sun or moon reflection and the current, also take into account the wind and the tide...
Left Side, Right Side, Middle Side, Inbetween Side? I think your best bet is to spend some time down there and work it out for yourself mate, you might have just been on the wrong side of the beach at that time, fish don't stop and wait for us, spend enough time at any spot and you'll get the feel for it and where the fish should be! People can give you reports on how they have gone, but they can't put you on the grain of sand to catch a fish, that my friend is what makes fishing fun! And the sense of achievement so much when you get on!
Good luck
