David and Kurt are linked by their mutual quest to discover/ rediscover the shipwreck. Their problems are symbolised by the shifting sands. The image of footprints both as a heading and within narratives suggests evidence – someone has been there but couples with images of sand show evidence can be lost like the ship/wreck. Again history is inconclusive. USE OF NARRATIVES
