An Automatic Identification System, or AIS, is basically an electronic transponder that is usually installed on a boat that identifies it. This is most common in marine locations. The transponder sends out a VHF signal on a continuous basis that provides information about a ship such as it’s name, type, position, and call sign.
This VHF signal is valuable because it relays information to other ships about its direction of movement as well as well as its speed. Received VHF signals then provide a visual display of all transmitting ships that are within a certain range. The system therefore provides a highly valuable service to water vessels in helping to track the progress of other watercraft in the nearby area. This decreases the chances of collision on the waterways. . The data that is received by other AIS-enabled vessels is most of the time displayed on a computer display screen or positioned as an overlay on a chart plotter. This will help to substantiate radar readout.
Ship captains use these devices to help make vital waterway navigation decisions so as to reduce the risk of collision. This system also is a valuable tool to help search and rescue operations. The device can pinpoint the exact position of a ship in trouble regardless of weather conditions.
Dangerous situations can be avoided by programming the system to track specific vessels. This information can be exchanged automatically by the ships captains allowing for safer navigation. Ships with over 300 tons of cargo & all passenger ships are required by the International Maritime Organization to be fitted with the marine guidance system. It is not required for recreational boats but it is increasingly becoming more popular. Globally, it is thought that this technology is is used in more than 40,000 maritime vessels.
Without a doubt, the technology’s primary use is to prevent collisions. The tracking does not work alone. VHF radio communications can be limited and considering the fact that every vessel isn’t required to have it, it is not the perfect solution. It is not an automated collision avoidance system as defined by the International Regulations for Preventing Collisions at Sea (COLREGS). In the hands of a skilled captain however, it is one of many tools utilized for safe travel.
During sea navigation, identifying other ships in the area is crucial for captains to make the best decisions on any voyage. That likewise does not mean that all other types of navigational observation is discarded. There is certainly, obviously, visual observation in which the captain will often make use of binoculars to position far away obstacles or boats. There is also acoustic observational warnings that a captain must pay attention for such as sirens, whistles, or VHF radio. Finally, there is radar or Automatic Radar Plotting Aid (ARPA) that can provide important navigational data to enhance what the AIS is plotting. Despite having all this kind of technology, incidents can even now occur. It is often due to time delays and the natural limits of radar or even just plain human error when this takes place. The graphical charts and all the other observational tools must be utilized if water travel is to be safe and AIS is a small part of that.
Kite surfing is becoming an extremely popular sport all over the world. You require some precise kite surfing gear before you set out to pursue kite surfing. They include an inflatable kite and a board along with some control equipments which will make sure that you are safe.

The kite surfing board is used by you to balance on when he is skimming over the waters tugged by your kite. This is another piece of equipment that is absolutely necessary in kite surfing. You have to ensure that like the kite even the kite board is one that will suit the condition of the water. A 14 to 18 meter square board would be best for someone who is just beginning to learn the sport and for places where the wind is not too high. They assist you to surf the waters comfortably with a good sense of equilibrium. The standard sized boards generally suit all surfers, but the boards that are still smaller are made use of by more experienced surfers who are quite comfortable with strong winds. These boards are also less heavy and can be utilized for acrobatics.
Kite surfing is extremely dangerous and cannot be pursued without the required control equipments. These equipments differ in relation to the kind of kite that is being used. Two lines inflatable kites have a two line control bar while four line kites have a four line control bar accordingly. The functioning of these control devices is very simple. You just have to tug on the bars to move it in what ever direction you want.
Normally all control systems are provided with a safety release system that is a vital factor of the kite surfing gear. The deadman safety release system is mandatory in all any control bar and it is capable of de-linking the kite from the surfer in the case of a crisis. The inflatable and the foil safety mechanisms will not operate if the rider becomes unconscious.
Before you set out to start kitesurfing, it is imperative that you take the necessary steps to learn how to use the control device and maneuver the kite. You will find that the kite reacts to any push-pull action on the control bar. Generally the quick release safety system is a part of the control bar when you buy one.
Another piece of kitesurfing gear is the harness that is available in different types like the seat harness and the waist harness. These help the surfer to lessen the tension on his arms. You also have the vest harness that can be used as a floating mechanism preventing the surfer from the sudden impact and harm.
You require owning pre-stretched surfing lines which are self oiled with a circular cross section to minimize the hauling of the wind to fly stably. Remember that this should be of a long lasting substance as it is on this that the rider depends for support.
You will also require a board bag, an Emergency Position Indicating radio beacon showing you where you are and an anemometer that will gauge the speed of the wind.

Kite Surfing provides the dual excitement of surf boarding as well as flying for the daring adventure seeker. The wind plays the most important part here, guiding the surfer through the water while he balances on surf or a kite board.
Before attempting this sport, you need to become proficient in flying a kite. As a first step, get a trainer kite which will help you master the speed and the controls.

Before you even think of using your brand new boat out for a cruise on the water it is in your own best interest to take a boat safety class and have a boat safety review to look for the mandatory safety equipment. The US Coast Guard can provide you with a list of required as well as proposed boat safety devices.
Life vests, or personal floating devices as they are formally called, should be easily available for every occupant of the vessel. They should also be adjusted to the built of the person who is designated to use them in case of an emergency. They must be in good working order including all the straps and clips in place and operational. It is a great idea to have them fitted to the individuals so that if required they can be put on without much further adjusting. In some states there is a minimum age for which the putting on of a life vest is obligated at all times.
As a huge factor of boating safety there must also be present on board a recently inspected fire extinguisher. It should be distinctly labelled so that anyone can locate it if needed and reach for it in time. There are varied kinds of fire extinguishers, designed to extinguish different kinds of fires. For boating safety it is advisable to obtain a Type B or C fire extinguisher, these are created for putting out fires initiated or fuelled by oil, grease and gas, or electrical fires.
As a last part of boating safety, especially for vessels with gasoline engines and particularly when the engine is mounted in the boat, great wind circulation is vital.
Not only to keep away from any build up of carbon monoxide, threatening the crew with poisoning, but also to limit gasoline fumes from building up and turning into a dangerous fire hazard.
