Predictions & assumptions
Timing follows the recorded route and its slower sections, reused in reverse for southbound trips. The three bridge sliders add assumed waits, not opening-schedule predictions. Stops are passage positions on the recorded route, not marina detours; Barnegat Inlet means the nearby ICW junction.
NOAA high/low tide times and heights are saved with this page. Heights between those events use a smooth cosine estimate and are marked estimated. Rising/falling refers to water level, not current direction.
Station ETAs refer to the closest passage position on your track. Stations in adjacent creeks or branches are shown with their offset; their tide may differ from the ICW. The route coloring interpolates nearby station heights and is a broader spatial estimate.
Best/lowest departures maximize/minimize the lowest tide height at Main Marsh Thorofare (8534393), Ludlam Bay, west side (8535221), Nummy Island, Grassy Sound Channel (8535661), Wildwood Crest, Sunset Lake (8535838), All Seasons Marina near the 34th Street bridge (proxy: NOAA 8534975), and the Atlantic City rail bridge (proxy: NOAA 8534638), evaluated at their individual pass-by ETAs. Only priority stations within the selected passage affect rankings; other stations remain informational. Short passages containing none of these six locations have no departure recommendation. This is not a least-depth or clearance calculation; local charted depths are not supplied, and saved boat draft and height are not yet used for clearance calculations. Passage duration does not change with tidal current.
The low-water alert checks the estimated tide at arrival against your chosen level (default 1.0 ft MLLW). It is an on-page alert, not a text, email or live monitoring service. Rail-bridge tide is evaluated on arrival, before its assumed wait. The two added checkpoint markers show your requested locations; their heights are explicitly nearby-station proxy estimates with no local time or height correction. Source details.
Predictions are feet above mean lower low water (MLLW), the usual tidal chart datum. Weather and wind-driven water-level departures are not modeled. A 2022 recorded route does not verify present channel depths or safe navigation.
