Why Waterproofing Matters in Waterproof Marine GPS and Chartplotter

Waterproofing is a critical feature for any electronic equipment intended for use in marine environments, where exposure to water is a constant threat. A waterproof marine GPS and chartplotter are designed to withstand the harsh conditions encountered at sea, including splashes, sprays, and sometimes even full submersion. Below, we delve into the importance of waterproof capabilities in marine electronics and explore the various standards of waterproofing.

Importance of Waterproof Capabilities in Marine Electronics

Waterproof capabilities are essential for any electronic device intended for use in marine environments. On the water, devices are constantly exposed to elements like rain, sea spray, and even direct immersion. Ensuring that marine electronics such as GPS and chartplotters are waterproof not only enhances their functionality but also extends their operational lifespan and reliability. Below are detailed reasons why waterproofing is crucial for waterproof marine GPS and chartplotters:

Protection Against Water Damage: Water can severely damage electronic circuits through corrosion or short-circuiting. Waterproof devices are sealed against such ingress, ensuring that their internal components remain dry and functional even when exposed to water.
Increased Reliability: Devices designed to be waterproof are inherently more reliable in marine settings. They are less prone to failures caused by moisture, which is particularly important for equipment relied upon for navigation and safety in potentially hazardous conditions.
Longevity of Device: Waterproof electronics are specifically designed to withstand the corrosive nature of saltwater and the varying temperatures of marine environments. This resistance significantly extends the usable life of devices, reducing the frequency and costs of replacements.
Safety in Rough Conditions: In rough sea conditions, high waves and rain are common, which can easily affect electronic devices. Waterproof chartplotters and GPS systems ensure continuous operation, which is vital for maintaining course and avoiding hazards.
Usability in All Weather: A waterproof marine GPS and chartplotter remain operational regardless of weather conditions. This feature is crucial for mariners who often have no control over environmental changes and must rely on their equipment in all scenarios.
Resale Value: Marine electronics that maintain functionality and appearance due to robust waterproofing tend to retain higher resale values. This makes them a better investment over time compared to non-waterproof models.
Compliance with Marine Standards: Many marine electronics need to adhere to specific safety and equipment standards that include waterproof ratings. Using devices that meet these standards ensures compliance with maritime regulations.
Peace of Mind: Knowing that your navigation systems are protected against water ingress allows sailors and marine operators to focus on navigating and managing their vessels, rather than worrying about equipment failure.
Cost-Effectiveness: While waterproof models may initially cost more, they offer better long-term value by avoiding the need for frequent repairs or replacements due to moisture damage, making them a more economical choice overall.

Different Standards of Waterproofing and Their Meanings for Marine Use

The degree of waterproofing in electronics is typically expressed through the IP (Ingress Protection) rating system, which describes the level of protection an enclosure provides against various forms of moisture and particulates. Here’s how different IP ratings translate to usability in marine environments, explaining their significance for waterproof marine GPS and chartplotter:

IPX0 – No Protection: Devices with this rating offer no protection against water, making them unsuitable for any marine application.
IPX1 – Dripping Water: This level protects against vertically falling droplets, such as condensation. It’s minimal and generally inadequate for open-water or exposed environments.
IPX2 – Dripping Water When Tilted: Offers protection when the device is tilted up to 15 degrees. While slightly better, it’s still insufficient for active marine use where spray and wave splash are common.
IPX3 – Spraying Water: Protects against spraying water up to 60 degrees from vertical. Suitable for interior marine environments but not for areas exposed to heavier splashing.
IPX4 – Splashing Water: Ensures protection against water splashes from all directions, making it appropriate for general marine activities but not for situations where the device might be submerged.
IPX5 – Water Jets: Can resist low-pressure jets from any direction, suitable for more exposed areas on a boat where equipment may be subject to stronger sprays.
IPX6 – Powerful Water Jets: Highly resistant to high-pressure water jets, this standard is suitable for deck-mounted electronics where sea spray and wave washing are frequent.
IPX7 – Immersion up to 1 Meter: Devices can withstand being submerged in water up to 1 meter deep for 30 minutes, ideal for accidental drops overboard or operations in very wet conditions.
IPX8 – Continuous Immersion: The highest standard, suitable for continuous submersion in water deeper than 1 meter, applicable for diving or high-endurance marine operations.

Each of these standards provides a framework to gauge the suitability of a waterproof marine GPS and chartplotter for various levels of exposure to water, helping users select the most appropriate model for their specific marine activities.

FAQs about Waterproof Marine GPS and Chartplotter

What is the difference between a GPS and a chartplotter?

A GPS (Global Positioning System) device provides geographic coordinates based on signals received from satellites, pinpointing a location anywhere on Earth. It displays latitude and longitude information and can show the direction and speed of travel. A chartplotter, on the other hand, extends the functionality of a GPS by integrating it with electronic navigational charts (ENCs). The chartplotter combines GPS data with these charts to create a dynamic map where your position, movements, and other navigational data are overlaid on the digital charts. This makes it easier to navigate waters as it shows not just where you are, but also your relation to nearby geographical features, underwater hazards, and navigation aids.

Do I need a chartplotter on my boat?

Whether or not you need a chartplotter on your boat depends on the type of boating you do. For casual boating near shore where you are familiar with the waters, a basic GPS may suffice. However, if you engage in more serious offshore boating, fishing in deep waters, or travel to unfamiliar areas, a chartplotter becomes invaluable. It provides enhanced situational awareness and safety by displaying detailed information about the waterways, including depth charts, buoy locations, and other crucial maritime data. Chartplotters can also integrate with other systems such as radar and sonar, increasing their utility further by aiding in navigation and obstacle avoidance.
