May 26, 2014 · The Williams & Heinz Maryland Cruising Guide map kit has tidal current charts for the Northern Chesapeake Bay (north of Cove Point) toward the back of the volume. I believe Reeds Nautical Almanac has them as well. The Bay has relatively benign tidal currents, but there are some places where it may affect you. In addition to tidal currents, some ...
Jul 11, 2008 · For tidal height it is the "rule of 12" 1-2-3-3-2-1. 1/12 the total change in the first hour, 2/12 the second hour, etc. I know of no similar general rule for currents. Current flows are just too variable. Consider the Cape Cod canal, 3 ft tides on one end, 9 ft tides on the other.
Jan 27, 2013 · 5054 posts · Joined 2000. #3 · Jan 27, 2013 (Edited) Several factors control the current in the C&D canal. 1. Tide amplitude on the Del River is 6ft., 1.5ft. on the Ches. Bay. 2. The Del River is a 'flowing river'.... adding to the tide height by virtue of its volumetric flow direction. 3.
May 26, 2022 · First off as others have said the the H/L tides do not match with the slack currents. If the current has a perfect sinusoidal rhythm, it will follow the rule of 12ths. Assuming the current runs for 6-hours. Hours 1 and 6 will have 1/12 tidal flow volume. Hours 2 and 5 will have 2/12 tidal flow volume.
Nov 8, 2017 · I'm looking for a website or an Android app that will show a single graph depicting predicted currents and tides. There are dozens of websites and apps that show graphs of predicted tides. I haven't found any websites or apps that show graphs of predicted currents. I would like a website or...
Jun 28, 2010 · Yes, I'm conservative, but with the currents, rocks, shoals etc in New England, I get an annual book - and with a sailboat and an auxiliary engine, I do want to know the exact start and end of favorable currents - think Wood's Hole, CC Canal, passage from Nantucket through the Race into LI Sound. Etc. My opinion.
May 23, 2012 · Are there any navigation software packages other than Nobeltec Odyssey that can do route planning with ETA's based on specific departure times and incorporating the impact of tidal currents? Odyssey does route simulations based on your entered departure time (or desired arrival time) that incorporate expected currents from current stations near ...
