Yes. Depends on size of the bay relative to the narrowness of the neck. Slack water will occur when the relative levels of the bay and "ocean" outside the bay are the same height (ignoring the effect of momentum of the tidal stream). OTBE, this will be somewhere close to mid-tide, and may only occur for a very short time. This is discussed in David Burch's book on kayak navigation, and Bascom's Waves and Beaches, also. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
