What this video covers
Jeanne Socrates departs Kingfisher Bay on Fraser Island just after 6 a.m., timing a solo southbound passage through the Great Sandy Strait to cross Sheridan Flats near high water.Watch The charted depth at Sheridan Flats is 0.2–0.4 metres — well below the 2-metre minimum her boat needs.1:08 A flood tide adds roughly 3 metres, bringing the effective depth to approximately 3 metres over the bar.1:08 She holds 5–5.5 knots to arrive at the flats around high water, leaving the smallest possible margin for error.0:57 The flood tide direction is confirmed by the boat swinging to point north, since the flood runs south in that stretch.0:29 Fraser Island, the world's largest sand island, shapes the entire geography of the strait: the shallows are sand accumulated over millennia, not rock, and the charted depths reflect that shifting substrate.1:50 Timing a departure to a specific speed in order to hit a tidal window over a near-zero-depth bar is the central technique demonstrated here.
