Whether you are interested in monitoring your vessel’s systems while underway or remotely from your home or office, Maretron’s N2KView^® software displays the information you need including engines, generators, tanks, rudders, navigation instruments, local weather, and much, much more. N2KView^® is completely user-configurable and you are free to create different screens for your exact needs while easily switching from screen to screen for monitoring all your systems. Digital displays, analog gauges, graphic displays, warning lights, and bar graphs, all can be configured exactly how you want them to be. You can even set the operating limits and color bands for analog gauges so you know when things are within limits and when they are not.

N2KView^® is a comprehensive vessel monitoring and control software that goes beyond simple monitoring. With N2KView^® you get additional functionality including alerts, video, control, and fuel management. The alerts functionality allows you to setup as many warnings and alarms as you need so you can be forewarned of potential problems. With alerts, you can relax knowing that the system is watching for smoke, CO, high bilge water, or anything else you deem important. N2KView^® video capability allows you to add cameras as part of the monitoring system - for example a camera in the engine room - or the cameras can be used as part of the security system. The control functionality gives you the ability to manage your electrical system; for example, you can turn lights or pumps on or off directly from N2KView^® and even tell if the lights or pumps are burned out and not working. Lastly, the fuel management function uses information from the fuel flow monitor, tank monitors, and GPS to provide advanced information like distance and time to empty as well as fuel rate and fuel economy.

N2KView^® software can run on your vessel's computer, or on standalone products like one of Maretron's TSM800C, TSM1330C displays or the Maretron Black Box (MBB300C) vessel monitoring computer.

If you want to run N2KView^® software on your vessel’s computer, you will need either a Maretron USB100 or an IPG100, which are necessary to get sensor information from the NMEA 2000^® network to the computer.

There is also a mobile version of N2KView^® which runs on iPhone or iPad, or an Android device. See N2KView Mobile for details.

Alerts are an important aspect of Maretron’s N2KView^® Vessel Monitoring and Control Software and when appropriately configured, alerts improve situational awareness and thus the safety of everyone onboard. Just think of all the things that need to be monitored to safely operate a vessel, for example is the bilge filling up with water, is there smoke or excessive heat in the engine room, are the batteries discharged, do I have enough fuel, is there carbon monoxide in the sleeping quarters, is there a door or hatch open, and the list goes on and on. You could create numerous N2KView^® favorite screens with indicators in order to manually monitor each parameter, but it’s awkward and inconvenient to constantly scroll through different screens to make sure all is well. This is where alerts within the N2KView^® software can dramatically improve safety without the need to manually and constantly monitor numerous screens. Once an alert is programmed within N2KView^®, the parameter is automatically monitored and you are immediately notified if something requires your attention. Notifications are sent to one or more annunciators, sounders, horns, or strobes placed throughout the vessel. And if you’re not onboard, N2KView^® can send an email or text message to notify you of any issues requiring your attention. It’s like having a second mate or engineer onboard monitoring your systems 24 hours day, 7 days a week, 365 days a year.

Generally an N2KView^® alert is configured so that if a parameter goes above or below a certain point, then the alert is triggered and the user is notified of the problem. An example of a simple “too high” alert is a notification if the refrigerator exceeds a certain temperature. Another example of a simple “too low” alert is a notification if a fuel tank drops below a certain level. Sometimes it is useful to go beyond simple high or low alerts and trigger an alert under a predefined condition. Take for example a generator running under no-load, which isn’t good for the generator (known as “wet stacking”). Unfortunately, a simple low load alert on the generator will produce a false alert when the generator is off, so we must define a condition during which time the no-load alert will trigger. For this particular example, we might choose a condition defined by the generator voltage greater than 100 volts, which indicates that the generator is indeed running. When the load is dropped (output power drops below 5 watts) and the generator is running (voltage is greater than 100 volts), an alert will trigger. If the generator is not running (voltage is less than 100 volts), the condition is no longer met and a false alert won’t occur. You can even go a step further and program a delay so the generator is allowed to run for some amount time without a load before the alert is triggered. In this way you can warm up the generator for 10 minutes before getting a notification to engage the load or cool it down for 10 minutes before receiving a notification to turn the generator off. This is just one example of a conditional alert with the potential to save thousands of dollars in unnecessary generator maintenance. Here is a table with some other examples of conditional alerts.

Setting and raising the anchor sounds simple. Winch it down when you want to stop and then winch it back up when you want to go.

Chapman says, “Sooner or later, carelessness and lack of technical know-how will lead to difficulty, possible danger.” (Maloney, 2006). Until now there has been no system available to comprehensively monitor and guide you through all the phases of planning, setting and retrieving your anchor. Most anchor watch alarm systems make fundamental errors such as using the GPS position to log the anchor drop point. This places the anchor directly under the GPS, resulting in errors of 10-15m and false triggers. Some serious mariners have resorted to apps on their phone and going to the bow to log the anchor position.

N2KView now includes a comprehensive Anchoring Module to make anchoring easier. Watch the video to see how N2KView can make anchoring easier for you.
