FAQs about Laptop Marine Chartplotters

What is the difference between a GPS plotter and a chartplotter?

A GPS plotter and a chartplotter, while often used interchangeably in casual conversation, actually refer to slightly different functionalities within marine navigation systems. A GPS plotter is primarily a device that uses Global Positioning System (GPS) technology to determine and display the geographical position of the vessel on a basic grid map. It is fundamentally focused on providing real-time location data.

A chartplotter, on the other hand, builds upon the basic functionality of a GPS plotter by incorporating detailed marine charts into its display. These charts include additional navigational data such as water depths, locations of navigation aids, potential hazards, and other pertinent marine information. Chartplotters are equipped with sophisticated software that not only shows location but also allows for route planning, tracking, and integration with other navigational systems like radar or sonar. This integration makes chartplotters essential for serious maritime navigation, offering a more comprehensive tool for planning and executing voyages safely and effectively.

Can I use a tablet as a marine GPS?

Yes, a tablet can be effectively used as a marine GPS with the right setup. Many modern tablets come equipped with built-in GPS modules, which means they can function without an internet connection. However, to utilize a tablet as a marine GPS effectively, you need to ensure it has a reliable GPS receiver and is compatible with marine navigation apps that are designed for plotting and route management on water.

Installing marine navigation software on your tablet can turn it into a handy chartplotter. Some popular apps available include Navionics, iNavX, and SeaPilot, which offer features ranging from chart updates, AIS integration, and route planning. Additionally, for enhanced accuracy and reliability, external GPS receivers that connect via Bluetooth can be used with tablets that lack robust internal GPS capabilities.

When using a tablet as a marine GPS, it’s important to consider the device’s durability and waterproofing. Many standard consumer tablets may not be suitable for the harsh marine environment unless they are protected with waterproof cases or are specifically designed for outdoor use.

What size screen is a chartplotter?

Chartplotters come in a wide range of screen sizes, catering to different vessel types and navigation requirements. The most common screen sizes range from 5 inches to 12 inches, measured diagonally. Smaller boats and personal watercraft might opt for compact units with 5- to 7-inch displays due to space limitations. These smaller units are typically easier to mount and handle in tight spaces.

Larger vessels, on the other hand, often require bigger screens for clearer visibility and more detailed chart presentations. Screens that are 9 inches or larger allow for better viewing of complex navigation information and are beneficial in planning and tracking long voyages. These larger screens also facilitate easier interaction with touch controls, especially under rough sea conditions. Ultimately, the choice of screen size should be influenced by the specific needs of the navigator, the size of the vessel, and how the chartplotter integrates with other onboard navigation systems.

Why are chartplotters so expensive?

Chartplotters are specialized devices that combine advanced GPS technology with sophisticated mapping software and robust hardware designed to withstand the harsh marine environment. Several factors contribute to the high cost of chartplotters:

Advanced Technology: Chartplotters incorporate high-precision GPS receivers, detailed electronic nautical charts, and the capability to integrate with various other navigation systems like radar, fish finders, and AIS, which all add to the complexity and cost of the device.
Rugged Construction: They are built to endure extreme conditions, including saltwater exposure, UV radiation, and vibrations, which necessitates the use of high-grade materials and watertight sealing technologies.
Software Licensing and Updates: The cost often includes licensing fees for the cartographic data and periodic updates to ensure the accuracy and reliability of the navigation information.
Market Niche: The marine electronics market is relatively specialized and does not benefit from the economies of scale seen in more mass-market consumer electronics, which can also contribute to higher prices.

Despite their cost, chartplotters are considered a crucial investment for serious mariners due to their integral role in ensuring safe and efficient navigation.
