Thanks for all the informative replies to this question. It seems that a bottleneck will not have slack water coincide with high or low water. So the only way to predict the best time to pass through the bottleneck is either from accumulated experience, published on charts, tide stream tables, sailing directions, or pilot, or maybe a local fisherman. If none of these are available for the location, perhaps it's best to allow plenty of time to hang around and wait. We have this situation nearby at "The Narrows", the eastern entrance to Westernport Bay. At the narrowest, the bottleneck is 600 metres or so wide. The chart marks 5 - 6 knot streams, but unlike the western entrance, used by shipping, there are no time predictions. I gather that the annual swimming event crossing this section is timed for slack water. A boat is placed mid strait. When the boat stops drifting, the starter's gun fires.
