Communicate Everywhere - Ashore And Aboard

It is important to have a high quality communication system on board to ensure safety for boaters. Before, you set out, it is advisable to make sure the boat is equipped with More Than one communication device, so that it can be used to send out emergency signals while on board or call for help. Accidentally, numerous boaters die, as they do not have equipment to send out an emergency call and they do not get timely help.

Some of the important communications equipment that enables efficient communication while on the water is discussed below:

Marine VHF Radio: This equipment is usually installed on all boats and is used for a range of purposes. It is mainly used to communicate with other boaters or the nearest marina or service facility. It is also a very useful device for summoning rescue service. The VHF radio that operates in the VHF frequency between 156 and 174The VHF radio that operates in the VHF frequency between 156 to 174 MHZ is widely used for avoiding collision of ships at sea 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.

VHS with DSC: Many newer VHS radios are not available with DSC. Activating the DSC DISTRESS function will transmits a MAYDAY which will consist of vessel identification, coordinates and time, to facilitate prompt response. Another importnat advantage of the DCS is the ability to easily share position info with other DSC-equipped vessels using the position request and advanced 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.

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. Handheld VHF radios are usually water resistant or water proof, sometimes float and can be used as an emergency communication devise in the event of a ditching. They also feature various NOAA weather broadcasting stations.

Marine Speakers: Marine speakers, unlike the ordinary speakers, are of much higher standards. They are specifically built to withstand harsh conditions of the sea. Amplifiers, speakers and subwoofers make up a complete marine entertainment system. The main behind load hailer speakers is to make loud announcements and instructions to make sure that any nearby person hears them. The loud hailer can also be used as a fog signaling devise

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. Those radiotelephones are built in a way that they withstand the rigors of the seas. Some radiotelephones also have emailing capabilities. Operating a Single Side Band radio demands a Ham Radio license. Most of the newer Single Side Band radios have Digital Signal Processing (DSP) virtually eliminates noise and interference and operate on 1300 channels.
