Whois & Analysis for tide-forecast.com

Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth.

A harbor or harbour (see spelling differences), or haven, is a body of water where ships, boats and barges seek shelter from stormy weather, or are stored for future use.

The term "harbor", referring primarily to a sheltered body of water, is often used interchangeably with "port", which is a man-made facility built for loading and unloading vessels and dropping off and picking up passengers.

Ports are often located in harbors.

A port is a location on a coast or shore containing one or more harbors where ships can dock and transfer people or cargo to or from land.

Port locations are selected to optimize access to land and navigable water, for commercial demand, and for shelter from wind and waves.

Ports with deeper water are rarer, but can handle larger ships.

Since ports throughout history handled every kind of traffic, support and storage facilities vary widely, may extend for miles, and dominate the local economy.

Some ports have an important military role.

A nautical chart is a graphic representation of a maritime area and adjacent coastal regions.

Depending on the scale of the chart, it may show depths of water and heights of land (topographic map), natural features of the seabed, details of the coastline, navigational hazards, locations of natural and human-made aids to navigation, information on tides and currents, local details of the Earth's magnetic field, and human-made structures such as harbours, buildings and bridges.

Nautical charts are essential tools for marine navigation; many countries require vessels, especially commercial ships, to carry them.

Nautical charting may take the form of charts printed on paper or computerized electronic navigational charts.

Recent technologies have made available paper charts which are printed "on demand" with cartographic data that has been downloaded to the commercial printing company as recently as the night before printing.

With each daily download, critical data such as Local Notice to Mariners is added to the on-demand chart files so that these charts will be up to date at the time of printing.

A coastline or a seashore is the area where land meets the sea or ocean, or a line that forms the boundary between the land and the ocean or a lake.

A precise line that can be called a coastline cannot be determined due to the Coastline paradox.
