Regular price $19.99 Save $-19.99TIDELOG© is a graphic almanac based on official National Oceanic and Atmospheric Administration (“NOAA”) and United States Naval Observatory (“USNO”) tide, current, and astronomical predictions specific to each geographical area. These areas are graphed to give you a visual picture of each day’s conditions… at a glance!
Tidelog’s graphics make it hard to go wrong. This is why Tidelog is favored not only by recreational boaters, but also by commercial, scientific and industrial users.
Repeat customers include many of the big names in shipping, tugboat, piloting, engineering, construction, flood control, pollution control, aquaculture, police, harbormaster and other maritime professions.

This helps you make real-world assessments of the conditions you’ll face. For example, “the current ebbs all afternoon; low tide is just after dark; there will be no moonlight until late… so we’ll want to be in by about 6 to be sure we clear the shoals (remember that other time?) and still have enough light to see.” Other tide books lack this information.
Teaches without words! Watch the tides change with the moon’s phase, distance (apogee, perigee) and declination (north, south or over the equator). See the relationship between tides and currents; for example, low tide rarely corresponds to maximum ebb, nor even to slack before flood. (This is often news even to experienced boaters, but is simply a result of the inertia of a moving body of water.)
Everyone makes them. We’ve seen even old hands misread a “baitshop” tidebook: “Oh, I was reading the a.m. column and thought it was p.m.!” Tidelog’s graphics make it hard to go wrong.
Tidelog is favored not only among recreational boaters, but also by commercial, scientific and industrial users. Repeat customers include many of the big names in shipping, tugboat, piloting, engineering, construction, flood control, pollution control, aquaculture, police, harbormaster and other maritime professions. Tidelogs are used to combat whale strandings on Cape Cod, to predict geothermal activity in California, to harvest geoducks in Washington state, locate fossils in Chesapeake Bay and to plan kayaking trips on Tybee Island.
Built to last and survive heavy usage. Nice, gold-imprinted cover. Permanent, lay-flat binding.
