Notices to Mariners Week 27 reports a new survey of the Swin Spitway by Roger Gaspar, author of Crossing the Thames Estuary. He has produced the very useful PDF of his latest survey showing the best water a little East of the buoyed Spitway and waypoints for the suggested transit for deeper draft vessels near low water. Well worth putting them in your plotter if heading up that way, as we normally get there near low water.
