Platinum+ Regular on SD / microSD Card from Nautic Way Maritime Bookshop

Introduction

The Navionics Platinum+ Regular digital marine chart on an SD or microSD card is electronic charting designed for marine GPS systems and chartplotters compatible with Navionics charts. It combines detailed marine cartography with advanced visualization and analysis features, including high-resolution shaded relief, satellite imagery, aerial photography and 3D views, depending on the reference and the capabilities of the equipment being used.

The term Regular refers to a geographical coverage category. It does not mean that the chart contains less detailed or less accurate nautical data than a Platinum+ Large chart. The main difference between Regular and Large concerns the geographical extent of the selected reference.

A Navionics Platinum+ Regular chart can therefore be particularly suitable for sailors who want coverage corresponding closely to their usual sailing area while benefiting from the premium features of the Platinum+ range.

However, choosing a digital chart should always take three essential factors into account: the exact chart reference, the geographical area covered and compatibility with the GPS or chartplotter.

What is a Navionics Platinum+ Regular marine chart?

Navionics Platinum+ is Navionics' premium range of digital marine charting. It includes the chart content available with Navionics+ and adds advanced visualization features. Garmin identifies detailed nautical charts, SonarChart HD bathymetry, Community Edits, Dock-to-Dock routing, SonarChart Live and various advanced charting options among the available features. Platinum+ additionally provides features such as high-resolution shaded relief, satellite imagery, aerial photography and 3D views.

The chart is supplied on an SD or microSD card depending on the reference and compatible system. It is designed for use in a marine GPS or chartplotter compatible with Navionics charts.

A Navionics Platinum+ Regular microSD card should therefore not be confused with a navigation application for smartphones or tablets. The physical card is intended for compatible marine navigation equipment.

What does “Regular” mean in Navionics Platinum+?

Regular refers to a geographical coverage category offered by Navionics. It is not a lower level of chart accuracy or quality.

A Platinum+ Regular chart can therefore provide the same main families of data and Platinum+ features as a Large reference, but over a different or more targeted geographical area.

The exact extent always depends on the chart reference. For example, a Regular chart may cover a specific maritime region, while a Large reference may cover a broader geographical area.

It is therefore preferable to choose according to the sailing area actually required rather than considering Regular as a “reduced” version of Platinum+.

Detailed marine charting

Navionics Platinum+ charts provide detailed marine cartography for coastal and inland waters. Depending on the area, the data may include:

• coastlines;

• depths and soundings;

• bathymetric contours;

• ports and marinas;

• navigation aids;

• hazards and obstacles;

• wrecks;

• tidal and current information;

• waterways and inland navigation data.

The availability and level of detail depend on the charted area and the specific reference.

This cartography can be used to plan a route, study a harbour approach, navigate along a coastline or analyse an area before going to sea.

SonarChart HD and bathymetry

Navionics Platinum+ also includes SonarChart HD, Navionics' high-definition bathymetric charting.

Depth contours make it easier to understand seabed configuration and variations in depth. This information is particularly useful for sailors who want to study the bathymetry of an area, as well as for anglers looking for depth changes and underwater structures.

On compatible equipment, SonarChart Live can display or create bathymetric charting in real time using data from the vessel's sounder. Availability depends on the equipment and its configuration. The Garmin/Navionics compatibility guide specifies the functions available on different compatible chartplotter models.

Platinum+ premium features

One of the main benefits of Platinum+ Regular compared with standard Navionics+ charting is its additional chart visualization features.

Platinum+ can provide overlays such as high-resolution shaded relief, satellite imagery and, depending on the area and equipment, other visual content. Garmin also lists aerial photography and 3D views among the Platinum+ features.

These features complement the traditional interpretation of electronic marine charts with more visual representations of the marine environment.

High-resolution shaded relief

Relief Shading provides a detailed shaded representation of underwater terrain. Changes in depth and seabed shapes can therefore be easier to interpret visually.

This feature can be particularly useful for:

• analysing seabed morphology;

• identifying bathymetric variations;

• planning a fishing trip;

• studying an unfamiliar sailing area;

• better understanding coastal and underwater terrain.

Satellite imagery

High-resolution satellite imagery is another characteristic feature of Platinum+. It can provide a more realistic representation of certain coastal areas.

It can be useful when approaching an unfamiliar area, examining the surroundings of a harbour or studying a coastline, while complementing the underlying chart data.

However, satellite imagery remains supplementary information. It does not replace official hydrographic data or direct observation from the vessel.

Aerial photography

Platinum+ can also provide aerial photographs of ports, marinas, infrastructure and other coastal features, depending on the covered area.

This information can help users understand their immediate surroundings when planning a port call or approaching a harbour.

3D view

The 3D view provides another representation of the charted area, with a perspective that can make certain land and underwater relief easier to visualize.

It is primarily an analysis and visualization tool. Availability depends on the chart reference and compatible equipment.

Example of use: coastal navigation

A sailor who regularly navigates along the same coastline can choose a Platinum+ Regular chart corresponding to that area.

Before departure, the navigator can review depths, ports, hazards and available chart information. Platinum+ visualization features can then provide additional information about underwater relief, coastlines and infrastructure.

Regular coverage can be particularly relevant when navigation is concentrated in a specific region and broader geographical coverage is not required.

Example of use: fishing

For fishing, the combination of marine charting, SonarChart HD and underwater relief visualization can be particularly useful.

The navigator can analyse depth contours, identify slope changes and examine the general structure of the seabed. High-resolution shaded relief can make underwater terrain easier to interpret.

SonarChart data and information recorded by the sounder should nevertheless be interpreted with the usual caution associated with bathymetric data and local conditions.

Example of use: harbour approach

When approaching an unfamiliar harbour, detailed charting makes it possible to review available information about approaches, depths, hazards, navigation aids and infrastructure.

Platinum+ visual features can provide additional information when preparing the approach, particularly through satellite imagery and aerial photography available for the relevant areas.

The navigator should nevertheless always check official nautical information and local conditions before and during the approach.

Dock-to-Dock routing and route planning

Charts compatible with Navionics functions may provide Dock-to-Dock routing. This technology can generate a suggested route between two points based on available chart data and selected parameters.

It can be useful for quickly planning a coastal passage or comparing different route options.

However, Garmin states that Dock-to-Dock routing is intended as a planning aid and does not replace prudent navigation. The suggested route must be checked by the navigator according to depths, hazards, restrictions, weather conditions and other relevant information.

SD or microSD: what is the difference?

Navionics Platinum+ charts are supplied on SD or microSD cards depending on the reference and equipment concerned.

The physical card format alone does not guarantee compatibility with a chartplotter. A device equipped with a microSD slot is not necessarily compatible with a Platinum+ chart.

The exact GPS or chartplotter model should therefore be checked against the Navionics compatibility guide.

The Garmin/Navionics guide currently available lists models compatible with Navionics+ and Platinum+ and details the functions accessible on each type of equipment.

Compatibility with a marine GPS or chartplotter

Compatibility is one of the main criteria when choosing a Platinum+ Regular digital marine chart.

Before selecting a reference, check:

• the make of the GPS or chartplotter;

• the exact model;

• the equipment generation;

• its software version;

• the supported SD or microSD format;

• compatibility with Navionics Platinum+;

• the exact chart reference;

• the required geographical coverage;

• the Platinum+ functions available on the equipment.

An important distinction must be made for Garmin equipment: Navionics+ and Platinum+ memory cards are not compatible with Garmin chartplotters. Garmin states that owners of Garmin chartplotters should use the appropriate Garmin Navionics+ or Garmin Navionics Vision+ charts for their equipment.

Activation and chart updates

Navionics Platinum+ charts supplied on memory cards include a one-year subscription providing access to the content and updates available during that period. Garmin states that once this period has expired, an active subscription is required to continue accessing new content, including daily chart updates.

Activation can be performed using the Navionics tools provided for this purpose, including Chart Installer.

For regular navigation, keeping electronic charts updated provides access to the latest available chart content. However, this does not replace official nautical information, Notices to Mariners, local regulations or weather information.

Who should choose Platinum+ Regular?

A Navionics Platinum+ Regular digital marine chart can be suitable for:

• sailors who mainly navigate within a specific region;

• coastal navigators;

• anglers using a compatible GPS sounder;

• users looking for detailed charting with advanced features;

• sailors wishing to use underwater relief visualization;

• users interested in satellite imagery, aerial photography and 3D views;

• boaters who do not require Large geographical coverage.

Regular therefore does not represent a lower level of quality. The choice between Regular and Large mainly depends on the geographical area required for navigation.

Key points to check before choosing a Platinum+ Regular chart

Before choosing a Navionics Platinum+ Regular marine chart on SD or microSD, it is recommended to check:

• the exact chart reference;

• the geographical area covered;

• the precise chartplotter model;

• compatibility with Platinum+;

• the SD or microSD format;

• the chartplotter software version;

• the functions available on the equipment;

• activation and update conditions.

The question is therefore not simply whether to choose a “Regular” or “Large” chart. The objective is to identify the combination that precisely matches the navigation requirement: reference + geographical area + compatible equipment.

Platinum+ Regular and electronic navigation

Digital marine charting is an essential part of modern navigation, but it should not be regarded as the sole source of information.

Even with detailed and regularly updated electronic charts, navigators should maintain a comprehensive navigation process: route planning, depth checking, consultation of official information, weather monitoring, visual observation and adaptation to actual conditions.

Automatic routing and visualization features should be regarded as decision-support tools rather than autonomous navigation systems.

Conclusion

The Navionics Platinum+ Regular digital marine chart on SD or microSD combines detailed nautical charting with a range of advanced features designed for compatible marine GPS systems and chartplotters. It includes the main features of the Navionics+ ecosystem and adds visualization options such as high-resolution shaded relief, satellite imagery, aerial photography and 3D views, depending on the reference and equipment.

The term Regular primarily refers to a geographical coverage category. It does not mean that the chart is less accurate or less comprehensive than a Platinum+ Large chart. The choice should be based on the geographical area actually required for navigation.

For coastal navigation, regional cruising, fishing or seabed analysis, Platinum+ Regular can provide a particularly rich charting environment.

Checking the exact reference, geographical coverage and compatibility with the GPS or chartplotter remains essential before use. Electronic charting should also be integrated into a comprehensive navigation process using official nautical information and applicable safety procedures.
