Displays the location of buoys for the State of Hawaii as recorded on NOAA nautical charts, which are used as aids to navigation (ATONs) to indicate traffic channels, to warn against potential dangers, or for other navigational purposes. Some include lights or radar reflectors to make them visible at night and in conditions of reduced visibility.

Displays the locations of lights for the State of Hawaii as recorded on NOAA nautical charts. These aids to navigation (ATONs) are used in conjunction with beacons and buoys to indicate traffic channels, to warn against potential dangers, or for other navigational purposes. In the IALA B maritime buoyage system (North and South America), red lateral markers have even numbers and should remain on your right when returning from sea ("red, right, returning") while green lateral markers have odd numbers and should remain on your left.

Boundaries of bottomfish restricted fishing areas (BRFA) for the State of Hawaii. It is unlawful for any person to take or possess bottomfish while in a vessel that is drifting or anchored within any BRFA. Bottomfish species covered by these rules include: a) 'ula'ula koa'e or onaga (Etelis coruscans); b) 'ula'ula or ehu (Etelis carbunculus); c) kalekale (Pristipomoides sieboldii); d) 'opakapaka (Pristipomoides filamentosus); e) 'ukikiki or gindai (Pristipomoides zonatus); f) hapu'u (Epinephelus quernus); and g) lehi (Aphareus rutilans).

Displays the locations of commercial harbors for the State of Hawaii. Commercial harbors and ports are harbors in which docks are provided with cargo-handling facilities.

Boundaries of available marine dumping zones for the State of Hawaii as recorded on NOAA nautical charts. Regulations for ocean dumping sites are contained in Title 40 ("Protection of Environment), Subchapter H ("Ocean Dumping"), Parts 220-229 of the U.S. Code of Federal Regulations (40 CFR 220-229). Additional information concerning the regulations and requirements for use of these sites may be obtained from the U.S. Environmental Protection Agency (EPA).

Boundaries of discontinued marine dumping zones for the State of Hawaii as recorded on NOAA nautical charts. These areas are no longer permitted for dumping. Regulations for ocean dumping sites are contained in Title 40 ("Protection of Environment), Subchapter H ("Ocean Dumping"), Parts 220-229 of the U.S. Code of Federal Regulations (40 CFR 220-229). Additional information concerning the regulations and requirements for use of these sites may be obtained from the U.S. Environmental Protection Agency (EPA).

Boundaries of fisheries management areas (FMA) for the State of Hawaii. The mission of the Hawaii Division of Aquatic Resources (DAR) is to manage, conserve and restore the state's unique aquatic resources and ecosystems for present and future generations. Major program areas include projects to manage or enhance fisheries for long-term sustainability of the resources, protect and restore the aquatic environment, protect native and resident aquatic species and their habitat, and provide facilities and opportunities for recreational fishing.

Displays the locations of launch ramps (slipways) for the State of Hawaii. While harbors may also have launch ramps, these sites solely provide a launch ramp and no other facilities. A launch ramp is a ramp on the shore by which small ships or boats can be moved to and from the water, usually from a trailer.

Displays the locations of some of the submarine sewer pipelines for the State of Hawaii as recorded on NOAA nautical charts, including Oahu as well as one each on Maui (Kihei) and the Big Island (Kona). Not all submarine pipelines are required to be buried, and those that were originally buried may have become exposed. Mariners should use extreme caution when operating vessels in depths of water comparable to their draft in areas where pipelines may exist and when anchoring, dragging, or trawling.

First introduced to Hawaii in 1967 with Hanauama Bay on Oahu, Marine Life Conservation Districts (MLCD) are designed to conserve and replenish marine resources. MLCDs allow only limited fishing and other consumptive uses, or prohibit such uses entirely. They provide fish and other aquatic life with a protected area in which to grow and reproduce, and are home to a great variety of species.
