The datum for charted depth shall be mean lower low water (MLLW) per enclosure 2.2.1. The contractor shall include official NOAA or other regulatory agency information on tidal ranges, periodicity and length of tide ranges, including a discussion on how contractor’s proposed use of tide heights to satisfy transit requirements may affect the shipyard availability arrival/departure times and the complete scope of work:

7.2.3.1. Underway in confined waters (harbors) – 3 feet of charted depth.

7.2.3.2. Underway in inland waters – 2 feet plus squat of charted depth. (Note:
