MaxSea Navigation Software

MaxSea navigation software, now integrated into the TIMEZERO ecosystem, is a marine navigation solution designed to plan, monitor and analyze sailing and powerboat navigation. It is suitable for cruising sailors, offshore navigators and professional users who need to combine digital marine charts, GPS data, AIS information, weather data and onboard instruments in a single navigation environment.

Marine navigation software does not replace the nautical publications and navigation documents required for safe navigation. Instead, it provides an additional tool for organizing navigation information, preparing routes and monitoring the vessel while underway. MaxSea/TIMEZERO can be used with different chart sources, tide and current information, weather data and information received from onboard navigation equipment.

MaxSea and the TIMEZERO range

The MaxSea name remains strongly associated with marine navigation software and electronic navigation. The current product family is built around the TIMEZERO environment, including TZ Navigator for recreational navigation and TZ Professional for professional maritime applications. Available functions depend on the software, version, installed charts and optional modules.

TZ Navigator is designed for different types of recreational navigation, including sailing, powerboating and racing. TZ Professional is intended for professional maritime users requiring a more advanced navigation environment.

This distinction is important when choosing MaxSea navigation software because charting, weather routing, radar, sounder, AIS and other specialized functions are not necessarily available in the same way in every configuration.

Digital marine charting with MaxSea

Marine charting is at the core of electronic navigation software. TIMEZERO uses a chart engine capable of displaying data in both 2D and 3D, with different chart sources depending on the geographical area and products being used.

The navigator can prepare a passage directly on the digital chart, display a specific marine area, search for locations, create waypoints and build a route. Depending on the available charts and data, the display can also provide additional information such as depth shading, tides, currents, satellite imagery or bathymetric data.

The ability to work with different chart sources makes it possible to adapt the navigation environment to the vessel and the cruising area. Depending on the configuration, users may work with vector or raster chart data from different marine chart providers.

During passage planning, digital charts can therefore complement paper charts from organizations such as Shom, Admiralty or NGA, together with the nautical publications appropriate for the intended area. The software provides an electronic planning environment while the navigator maintains a complete approach to navigation documentation.

Route planning with MaxSea

Route planning is one of the fundamental functions of marine navigation software. MaxSea/TIMEZERO allows users to create a sequence of waypoints defining a route between a departure point and a destination.

A route can be prepared for a short coastal passage lasting a few hours or for a multi-day offshore or ocean passage. The navigator can place waypoints while considering coastlines, hazards, restricted areas, available depths and expected conditions.

Route-planning tools can include:

• creating and modifying routes;

• adding waypoints;

• creating marks and annotations;

• recording and recalling tracks;

• checking selected route-safety parameters;

• displaying navigation data;

• activating a route during navigation;

• using GPS position data.

The TIMEZERO Route Planning Wizard can also take factors such as tides, currents and transit time into account when helping determine an appropriate departure time. This can be particularly useful for coastal navigation where tidal conditions influence departure or arrival.

GPS, instruments and navigation data

MaxSea/TIMEZERO can operate as a central navigation-data environment when connected to the vessel's electronic equipment.

Depending on the configuration, data may come from GPS, navigation instruments, AIS and other equipment using interfaces such as NMEA 0183 or NMEA 2000. Some configurations can also integrate with Furuno equipment and networks.

The software can then display the vessel's position, heading, speed, route information and other data received from onboard instruments.

This integration is particularly useful on an offshore sailing yacht. The navigator can prepare the route on the computer, monitor the vessel's actual position and compare planned navigation data with the conditions encountered at sea.

AIS and ARPA

The AIS function displays vessels equipped with AIS transmitters around the own ship. Received information can be displayed directly on the digital chart, helping the navigator identify and monitor surrounding traffic.

Depending on the configuration, TIMEZERO also provides AIS/ARPA functions. Targets can be monitored and selected alarms can be configured to draw attention to potentially dangerous situations.

AIS does not replace visual lookout, radar watchkeeping or normal collision-avoidance procedures. It is an additional source of information that can improve situational awareness.

During an offshore passage, AIS becomes particularly useful when traffic increases near commercial shipping routes, port approaches or traffic separation schemes.

Weather, tides and currents

Modern marine navigation software is no longer limited to chart display. TIMEZERO can integrate weather information such as wind, precipitation, cloud cover, air pressure, waves and selected oceanographic parameters.

Forecast information can be animated to show how weather conditions are expected to evolve over time. Tide and current information can also be used when planning a route.

These functions are particularly useful when comparing different navigation scenarios.

For example, when sailing between two ports affected by strong tidal currents, the navigator can study how the current may influence the departure time and passage duration. During an offshore passage, weather information can help identify favorable or unfavorable wind areas and anticipate changing conditions.

MaxSea weather routing

Weather routing is an advanced function of the TIMEZERO environment when the appropriate routing module is installed.

The principle is to calculate an optimized route using forecast weather, currents and vessel performance. For a sailing yacht, polar data can represent theoretical performance at different wind speeds and angles.

The routing algorithm uses an isochrone method to compare possible vessel movements over time.

A typical example is an Atlantic crossing. The direct route between two points is not necessarily the fastest or most suitable route. A slightly longer route may provide better wind conditions, avoid an area of weak wind or reduce exposure to an unfavorable weather system.

Weather routing remains a decision-support function. The navigator must evaluate the results, monitor forecasts, consider the limitations of weather models and apply sound nautical judgment.

Navigation safety and route monitoring

Electronic route planning should always be combined with proper nautical verification. TIMEZERO includes various functions designed to improve navigation safety, including route checks, alarms and a security cone depending on the software and configuration.

The security cone can help identify certain hazards or shallow-water areas located ahead of the planned vessel track when the required chart data is available.

Other alarms can relate to depth, anchoring or AIS/ARPA targets.

These functions should never be regarded as a substitute for chart reading, lookout procedures and normal navigation practices.

Coastal and offshore navigation

MaxSea/TIMEZERO can be used in many navigation situations.

For coastal navigation, the navigator can plan a route between ports, take tides and currents into account, monitor the GPS position and observe surrounding traffic through AIS.

For offshore cruising, the software can be used to prepare several passage legs, record tracks, analyze weather conditions and work with wind, current and wave information.

For ocean passages, weather-routing functions can provide additional decision support, particularly when combined with sailing polar data.

For professional maritime use, TZ Professional provides a more advanced environment including AIS/ARPA functions, S-57 chart support depending on the configuration, and a range of specialized modules.

MaxSea, digital charts and nautical publications

Electronic navigation software should be considered as one element of a broader navigation-documentation system. Digital charts do not automatically replace paper charts or nautical publications required for a particular type of navigation or under applicable regulations.

Navigators can therefore combine MaxSea/TIMEZERO with charts and nautical publications from recognized sources such as Shom, Admiralty or NGA, depending on the cruising area and products available.

Sailing directions, lights lists, nautical almanacs, navigation books, regulatory publications and other marine documents remain useful when preparing a complete passage.

The objective is to maintain consistent, current and appropriate information for the intended navigation area.

Who can use MaxSea navigation software?

MaxSea/TIMEZERO can meet the requirements of several types of users:

• sailing and powerboat cruisers;

• yacht and motorboat owners;

• offshore navigators;

• crews preparing ocean passages;

• racing sailors and navigators requiring routing functions;

• professional mariners;

• users integrating GPS, AIS and onboard instruments;

• navigators wishing to combine charting, weather and navigation data.

The choice between a recreational and professional configuration mainly depends on the type of navigation, onboard equipment and required functions.

Conclusion

MaxSea navigation software, through the TIMEZERO environment, provides a comprehensive solution for planning and monitoring marine navigation. Digital charting, routes and waypoints, GPS, AIS/ARPA, weather, tides, currents, safety functions and, depending on the configuration, weather routing or specialized equipment integration can be combined within the same navigation environment.

Its value is particularly clear when the software is used as a decision-support tool alongside marine charts, navigation instruments and nautical publications. From coastal sailing to ocean passages, MaxSea/TIMEZERO provides a structured environment for route preparation, real-time navigation monitoring and analysis of changing marine conditions.
