WHAT ARE THE BENEFITS OF COMBINING VHF, AIS AND MOBILE INTO A SINGLE DEVICE?


We all have a responsibility for


protecting our oceans and our local environment and on a superyacht the crew should be doing everything that they can to minimise the environmental impact of the yacht. Regulations controlling the discharge of grey and black water, bilge or ballast water are difficult to plot. Base line data is often affected by headlines and rocky outcrops, meaning yachts can be beyond the required distance from the coast by line of site, but still in a restricted area. It is not just the potential fines or delays that should be the main cause for concern however, but a social responsibility to ensure that our wonderful industry is not having a detrimental impact on some of the most precious places on the planet.


Most mobile contracts offer low cost roaming bolt-ons, but these aren’t always highlighted to the customer. To avoid sky- high data and roaming charges, there’s a few ways you can reduce use, without reducing your communication options. Before travelling, ask your provider to set a data roaming cap. You can also set a warning limit on your phone. Set iCloud syncing, app updates and any apps with background refresh to only do so on Wi-Fi connection. And take advantage of every Wi-Fi hotspot! Newer iPhones and Samsung handsets allow for an eSIM as well as a normal SIM, which allows you to add a local pay-as-you-go plan to your phone and avoid costly charges in areas not covered by your package. Choose a contract that suits the typical yachting routes and has bolt-on packages available. We love Vodafone - sometimes more expensive than other suppliers but best value for money.


Analogue radio


modulates one voice call for each 12.5kHz band, with no encryption making it easier for anybody to monitor crew and guest movements. However, despite their trusty and dependable nature, analogue radios remain an enormous security risk for keeping communications private on board. Digital radio encodes and encrypts the voice, allowing more channels for a frequency. This means that the calls are routed so that disciplines are securely separated. Deckhands and engineers can be contacted individually without other radios picking up the conversation, while the captain can still listen to them all. Unlike analogue, digital radio is feature- rich with text messaging, priority and private calling while enabling data transfer, allowing the transmission of alarms and service calls plus GPS location of handsets and tenders.


Combining disparate functions into a single system provides the user with a cohesive integrated experience, reducing install time, cost and complexity. Installation is simplified using a single box, eliminating external splitters and additional antennas. Operation becomes seamless with services like VHF, DSC and AIS operating congruently. This maintains service integrity for functions like AIS position reports, otherwise blocked by external splitters during VHF voice transmission. AIS targets on a plotter view quickly become contacts for DSC direct calling. Safety is improved by combining and prioritising alarms across multiple functions to a single device, keeping crew focused on what’s important and giving them the tools to act quickly. The convergence of VHF, AIS and MOB is logical for both the user and the installer, and will soon become the new standard in safety communication.
