This video is a basic introduction to sea charts. We will go through how to read depths and bridge heights, plot magnetic and true courses from the compass rose using a parallel ruler and how to measure distance in nautical miles. In particular detail is information on converting from magnetic to true and from true to magnetic. This is on of the fundamental skills required for coastal navigation.

A slick way to do echart navigation on google earth, as well as viewing all NOAA charts and even a fast way to download the RNC versions. NOTE: WE UPDATED THE LINK BELOW JAN 16, 2018 (thanks to PorcineJim ) Main link at NOAA describing the process https://nauticalcharts.noaa.gov/data/gis-data-and-services.html#seamless-raster-nautical-chart-services Direct link to the Google Earth file we need https://seamlessrnc.nauticalcharts.noaa.gov/rnc/noaa_rncs.kmz ( Note this only works with US charts because they offer free echarts, whereas most other nations do not. Brazil may be an exception, but they do not offer the Google Earth function that i know of. )

Polaris ships bridge simulator used to supplement maritime training courses at Diverso Impex - Maritime training center in Croatia. Check out the list of simulator STCW courses - http://goo.gl/SnRPGo Maritime training and crewing center DIVERSO IMPEX LLC is among the first companies that started with the professional training of seafarers in Croatia. Seafarers Training takes place on the cutting-edge teaching and simulation equipment (Ship’s Bridge Simulator Polaris, Arpa Radar, electronic maps, ship simulator, ROC, fire polygon, lifeboat, …), all with the participation of highly skilled and professional teachers with years of experience in the maritime industry. Diverso Impex LLC in Split is certified by ISO quality system. FULL MISSION BRIDGE SIMULATOR "POLARIS" by KONGSBERG is a device that is installed on the most sophisticated ships at the present. It is user friendly and the crew quickly adapts to work on it. The simulator can be used quite successfully on a plan of training students who are preparing themselves for the vocation of deck officer, and, subsequently, of shipmaster, but also for the training of already experienced mari¬ners with a lack of experience on a certain type or size of ship, as well as for the training of pi-lots. The display of the integrated navigation system on the bridge, where all devices are networked to assist the navigator in the conduct of the ship. 1. ECDIS (Electronic Chart Display & Information System) Electronic navigation map, which replaces the existing paper maps, all ships must be equipped with the same in the near future. The map has two kinds of image displays: raster and vector. IMO (International Maritime Organization) - is linked to the electronic ticket and imposes the use of vector map in ECDIS due to the possibility of integration of the maps with other devices in the IBS (Integrated Bridge System) 2. ARPA (Automatic Radar Plotting Aids) It is a device used for the detection of other objects in the area and for avoiding them. The machine itself is connected to a Doppler log and Gyro compass it has the possibility of overlap with the navigation map which is good to verify the position of the ship. 3. CENTRAL CONSOLE consist of CENTRAL DISPLAY UNIT - It consists of other navigation devices networked to form an integrated navigation systems such as: GPS / DGPS - device for positioning the ship AIS - Automatic Identification System - a device that provides information obout the ships in the area ( the name of the ship, its call sign, MMSI number, etc.) DOPPLER LOG – A device for reading boat speed through the water ECHO SOUNDER - A device for determining the depth of the sea under the boat MAGNETIC COMPASS REPEATER GYRO COMPASS REPEATER INCLINOMETER - A device which reads the tilt of the boat (left – right) WIND INDICATOR - A device that gives us the relative wind speed and the wind direction. CENTRAL COMAND BOARD – therein lies the steering wheel , auto pilot, engine telegraph, BOW Thruster Controller , STERN Thruster Controller , VHF radio.

Two Arleigh Burke-class destroyers — the USS Spruance and the USS Preble — conducted a Freedom-of-Navigation operation on 11th Feb. They sailed within 12 nautical miles of Chinese occupied Spratly Islands. China claims almost all of the South China Sea and is trying to establish de facto control of the waters. It wants all ships & aircraft navigating in the area to identify itself to the Chinese Navy. Vietnam, Philippines, Malaysia, Brunei, and Taiwan also have claims on these waters but China has outmuscled them and set up military infrastructure in the many islands including the Spratly Islands. The South China Sea route is significant as about $5 trillion in trade and almost 50% world’s oil shipment passes through it each year. The waters are also thought to have 11 billion barrels of untapped oil and 190 trillion cubic feet of natural gas. Countries like the US, Japan and India have no claims in the area and want ‘Freedom of Navigation’ as per international maritime laws. Cmdr. Clay Doss, a US Navy 7th Fleet spokesman, told CNN that the purpose was "to challenge excessive maritime claims and preserve access to the waterways as well as to show that the US will fly, sail, and operate wherever international law allows” Viewers may note that the US conducts Freedom-of-Navigation regularly. As usual, Beijing has reacted to the operation sharp manner As reported by the South China Morning Post, Chinese foreign ministry spokeswoman, Hua Chunying, accused the US of entering Chinese waters without permission and engaging in provocations that threaten China's sovereignty, In this video, Defense Updates analyses why China should fear USS Spruance and USS Preble?

It hasn’t been easy to rally the whole world behind us.” Yet at the same time, some ecologists fear that such a map will also aid mining industries who seek profit in the previously unattainable depths of the Earth.” The Ocean: Haven’t We Already Mapped It? https://schmidtocean.org/cruise-log-post/the-ocean-havent-we-already-mapped-it/ “Most of the seafloor that has been mapped thoroughly is close to shore. Thanks to all of the hydrographers that constantly survey the world’s coastlines, we now have nautical charts (specialized maps) that are used to safely navigate ships. Coastal areas are well surveyed and often re-surveyed because seafloor conditions continuously change, especially close to shore. Hydrographers make sure that ships have the information they need to navigate safely by detecting and reporting new hazards to navigation with each chart update.” ____________________ How close are we to colonizing the moon, mapping the human brain and curing cancer?

An animated infographic depicting China’s territorial disputes. Is China trying to expand its territory? Click here to subscribe to The Economist on YouTube: http://econ.trib.al/rWl91R7 ONE reason China’s spectacular rise sometimes alarms its neighbours is that it is not a status quo power. From its inland, western borders to its eastern and southern seaboard, it claims territory it does not control. In the west, China’s border dispute with India is more than a minor cartographic tiff. China claims an area of India that is three times the size of Switzerland, the state of Arunachal Pradesh. Further west, China occupies Indian claimed territory next to Ladakh in Kashmir, an area called the Aksai Chin. China humiliated India in a brief, bloody war over the dispute in 1962. Since 1988, the two countries have put the dispute on the backburner and got on with developing commercial ties, despite occasional flare-ups. More immediately dangerous is the stand-off between China and Japan over disputed islands in the East China Sea, known as the Senkakus in Japan and Diaoyu in Chinese. Japan says they have always been its territory and admits no dispute, claiming also that China only started expressing an interest when it began to seem the area might be rich in oil and gas. A new and much more dangerous phase of the dispute began in 2012 after Japan’s government nationalised three of the islands by buying them from their private owner. China accused Japan of breaking an understanding not to change the islands’ status. Ever since, it has been challenging not just Japan’s claim to sovereignty over the islands, but its claim to control them, sending Chinese ships and planes to patrol them. Raising the stakes is Japan’s alliance with America, which says that though it takes no position on who owns the islands, they are covered by its defence treaty with Japan, since it administers them. Especially provocative to America and Japan was China’s unilateral announcement in November 2013 of an Air-defence Identification Zone, covering the islands. The worry is less that big powers will deliberately go to war over these desolate little rocks, but that an accidental collision at sea or in the air might escalate unforeseeably. Similar fears cloud disputes in the South China Sea, where the maritime claims in South-East Asia are even more complex, and, again, competition is made more intense by speculation about vast potential wealth in hydrocarbon resources. Vietnam was incensed in May 2014 when China moved a massive oil-rig to drill for two months in what it claimed as its waters. This was near the Paracel Islands, controlled by China since it evicted the former South Vietnamese from them in 1974. To the south, China and Vietnam also claim the Spratly archipelago, as does Taiwan, whose claim in the sea mirrors China’s. But the Philippines also has a substantial claim. Malaysia and even tiny Brunei also have an interest. But it is with Vietnam and the Philippines that China’s disputes are most active. The Philippines accuses China of salami-slicing tactics, stealthily expanding its presence in disputed waters. In 1995 it evicted the Philippines from Mischief Reef, and in 2012 from Scarborough Shoal. This year it has tried to stop the Philippines from resupplying a small garrison it maintains on the Second Thomas Shoal, and appears to be building an airstrip on the Johnson South Reef. The United Nations Convention on the Law of the Sea—UNCLOS—is one forum for tackling these disputes. But UNCLOS cannot rule over territorial disputes, just over the waters habitable islands are entitled to. And China and Taiwan point to a map published in the 1940s, showing a big U-shaped nine-dashed line around the edge of the sea. That, they say, is historically all China’s. This has no basis in international law, and the Philippines, to China’s fury, is challenging it at an UNCLOS tribunal. In fact China often fails to clarify whether its claims are based on the nine-dashed line, or on claims to islands, rocks and shoals. That lack of clarity alarms not just its neighbours and rival claimants, but the United States, which says it has its own national interest in the freedom of navigation in a sea through which a huge chunk of global trade passes Also alarming is that if these arguments over tiny specks in the sea become so unmanageable, what hope is there for resolving the really big issues? And the biggest of all is the status of Taiwan, still seen by China as part of its territory, but in practice independent since 1949. For now, Taiwan and China have a thriving commercial relationship. But polls suggest that few in Taiwan hanker after unification with the mainland. And China’s rulers still insist that one day they will have to accept just that.
