Eldridge Tide and Pilot
Ok, I am being cheap and do not want to buy another Eldridge for 2010. Besides I only use the current charts and really nothing else in the book beyond the occasional general reading. Typically we sail in Nantucket and Vinyard sounds and occasionally Block Island Sound. I use Eldridge for sailing with favorable currents. This year I was wondering if I just print the tide table for Boston Harbor off the web (more or less free) would the current diagrams in Eldridge hold true? That is, if I know the time of the tide at Boston Harbor would the estimated current velocities shown in Eldridge be constant more or less each year? Understanding that different moon phases will also increase or decrease the current strength. Any thoughts would be helpful.
