The ʻAuʻau Channel is one of the most protected areas of ocean in the Hawaiian Islands, lying between Lānaʻi and Maui. The channel is also protected by Molokaʻi to the north, and Kahoʻolawe to the south. The depth of the channel reaches 108 feet (33 m), and its width is 8.8 miles (14.2 km).
Māui sailed a canoe called Mahaanui and after he had pulled up the North Island (Te Ika a Maui) he left Mahaanui on top of a mountain in the foothills behind what is now Ashburton. That mountain now bears the name Mahaanui, [13] and the coastline between Banks Peninsula and the Waitaki River is called Te tai o Mahaanui (the tides of Mahaanui).
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
Maui (center right, with Molokaʻi, Lānaʻi, and Kahoʻolawe to its left) as seen from the International Space Station [2] Maui (/ ˈ m aʊ i /; Hawaiian: ) [3] is the second largest island in the Hawaiian archipelago, at 727.2 square miles (1,883 km 2). It is the 17th-largest in the United States. [4]
Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).

Waiʻanapanapa State Park is a 122-acre (0.49 km 2) state park in Hana, on the island of Maui, in Hawaii. It is located at the end of Waiʻanapanapa Road off Hana Highway at mile marker 32, 53 miles (85 km) east of Kahului, Maui.
Tide flow information is most commonly seen on nautical charts, presented as a table of flow speeds and bearings at hourly intervals, with separate tables for spring and neap tides. The timing is relative to high water at some harbour where the tidal behaviour is similar in pattern, though it may be far away.
