Communication In Land And Sea
It is important to have a high quality communication system on board to ensure safety for boaters. Prior to the journey, it is advisable to ensure the boat is equipped with more than one communication device, so that it can be used to send out emergency signals while on board. Accidentally, numerous boaters lose their life, as they do not have equipment to transmit an emergency signal and they do not get timely help.
Some of the important communications equipment that enables efficient communication while on the water is discussed below:
Single Sideband Radiotelephone: This high-powered radio is an ideal tool, which is used for long range communications usually by long distance cruisers and commercial operators. These radiotelephones are built in a way that, they are capable of withstanding the rigors of the seas. Some radiotelephones also have emailing capabilities. Operation of a Single Side Band radio requires a Ham Radio license. Most of the innovative Single Side Band radios have DSP that virtually eliminates all noise, operating 1300 channels.
Marine Speakers: Marine speakers, unlike the ordinary speakers, are of much higher standards. They are specifically desinged to withstand harsh sea conditions. Amplifiers, speakers, subwoofers make up a complete marine entertainment speaker system. The main purpose of using load hailer speakers is to produce loud announcements and instructions so everybody hears them. The loud hailer can also be used as a fog signaling devise.
VHF Handheld Radio: While not a requirement a hand held VHF radio can serve as an inexpensive spare radio in case of a malfunction of the installed radio. Portable VHF radios are usually water proof, and can generally be used as an emergency communication devise in case of a ditching. Those also include various NOAA weather broadcasting stations.
VHS with DSC: Many newer VHS radios are not available with DSC. Activating the DSC DISTRESS function will send a MAYDAY which will consist of vessel identification, Latitude / Longitude and time, to receive prompt response. Another importnat advantage of the DCS is the ability to easily share location info with other DSC-equipped vessels using the location request and other position sharing functions. With the push of a few buttons you can request the position of another vessel, or simply send your position information to the vessel you select.
Marine VHF Radio: This equipment is usually installed on all boats and is used for a range of purposes. It is majorly used to communicate with other boaters or nearby port or service facility. In addition, it is regarded as a very helpful device for summoning rescue service. The VHF radio that operates in the VHF frequency (156 to 174) MHZ is vastly used for preventing collision of vessels at sea. Marine VHF Radio mostly works on the principle of 'simplex' transmission, where communication takes place in only one direction at a time.
