Why use a marine navigation software to prepare a route, a journey, or a marine expedition?

Marine navigation software has become an indispensable tool in the world of offshore racing. It is critical for race directors to ensure the most accurate preparation and conduct of a competitive race.

The question of whether to install electronic chart software can arise for coastal navigation (cruises or racing) and for offshore trips, so it is very important to identify the merits of using this type of tool….

If a reminder was necessary, the sea is of course, a formidable environment. It requires accurate planning, both on land and at sea. This anticipation is needed in order to fully understand, prepare and carry out navigation with good seamanship.

The following factors affect each and every route navigated: the distance and time needed to cover it depending on the boat specs, the type of coastline and its dangers, weather and sea conditions, tidal currents, the ports or shelters along the route etc.

Nowadays, a navigation software installed on a laptop such as TimeZero developed by MaxSea, allows integration with, and quick and easy access to all of the above elements in just a few clicks of the mouse.

Whether you are at home in the preparation phase, or in live navigation mode, course preparation is made extremely comprehensive, and also allows a high level of interface customization.

The TimeZero software features a wide zoom level on charts, (which is identical to SHOM charts, and should therefore remain “familiar-looking”) which is the equivalent of having a wide portfolio of paper charts immediately accessible. Thus the tools zoom-in and zoom-out then allow you to have a good visual picture of the desired navigation area.

TimeZero allows you to overlay satellite photos on your chart, so that you can visualize specific places in advance, and plan a correct approach to the area!

It is possible to simultaneously create a course outline using the “route” tool and to start live navigation. With just a few clicks along the way, you have your route, distance and direction (true or magnetic option) between each waypoint, as well as the cumulative distance. You can name each waypoint, and insert or move a waypoint at any time during navigation of the route.

Preparing a route becomes fun and you can always refer back to your navigation logbook. By making all the possible adjustments, a basic route gradually transforms into a detailed course, corresponding with your expectations such as your safety criteria in relation to distance from shore or a shoal, a place that you want to see up close etc.

All data created in the software can then be saved with the route name, and even assigned to a specific layer, which as its name suggests can be displayed or hidden according to your wishes. Once activated, this route can be exported to your GPS for rapid access to route information.

Once the software is integrated with onboard navigation hardware (GPS and other suitable instruments) TimeZero is transformed into an even more powerful navigation aid. Your boat is symbolized by an icon to scale that moves in real time on your screen, as simple as a video game.

After importing the marine weather forecast file (commonly known as a “GRIB” file), you can launch the routing function to optimize your route by integrating the effects of weather conditions on your route. You can also calculate the ETA on the next waypoint or decide the fastest route to reach your end point. The routing function and comprehensive weather of TimeZero opens the door to anticipation, and accurate planning.

In conclusion, after many years at the chart table equipped with a Cras Ruler, a handheld compass and dividers, with an eye on the GPS, it now seems essential to have TimeZero onboard, whatever the intended sailing, inshore or offshore, whether racing or cruising!

Happy navigating to all of you this summer.
