Interesting facts about Maritime Chart
1: Maritime Chart Paper is Waterproof
Maritime chart paper is specially designed to be waterproof. It is made from synthetic materials that can withstand exposure to water, ensuring that the charts remain intact even in wet conditions.
2: It Resists Tearing and Fading
Maritime chart paper is highly durable and resistant to tearing. It can withstand rough handling and remains intact even when subjected to frequent folding or unfolding. Additionally, it has excellent resistance to fading, ensuring that the charts retain their clarity over time.
3: It Features Anti-Glare Properties
To enhance readability under various lighting conditions, maritime chart paper often incorporates anti-glare properties. This reduces the reflection of light on the surface of the paper, making it easier for navigators to read and interpret the information displayed on the charts.
4: The Paper Is Designed for Precision Printing
Maritime chart paper undergoes a meticulous printing process to ensure accurate representation of geographical features. High-precision printing techniques are employed to achieve precise line thicknesses, colors, and details necessary for accurate navigation.
5: It Meets International Standards
The production of maritime chart paper adheres strictly to international standards set by organizations such as the International Hydrographic Organization (IHO). These standards define specific requirements for color schemes, symbols, and other elements used in nautical charts.
6: Chart Paper Sizes Vary Globally
The sizes of maritime chart papers vary across different regions around the world. For example, in Europe and most parts of Asia, A0 size (841mm x 1189mm) is commonly used for large-scale charts, while in the United States, the B size (11 inches x 17 inches) is often preferred.
7: Chart Paper Series Follow a Specific Order
The series of maritime chart paper follows a specific order known as the "A-series" and "B-series." The A-series includes sizes A0, A1, A2, A3, and so on. Similarly, the B-series includes sizes B0, B1, B2, B3, and so forth. Each subsequent size is half the area of its predecessor.
8: Maritime Chart Paper Originated from Parchment
The use of parchment for maritime charts dates back to ancient times. Parchment was initially used due to its durability and resistance to water damage. Over time, advancements in papermaking techniques led to the development of specialized waterproof chart paper.
9: Electronic Charts Are Gaining Popularity
With advancements in technology and navigation systems, electronic charts are becoming increasingly popular among mariners. However, traditional maritime chart paper continues to be used as a reliable backup option in case of electronic failures or emergencies.
10: Chart Paper Is Essential for Safe Navigation
Maritime chart paper plays a crucial role in ensuring safe navigation at sea. It provides vital information about water depths, navigational aids like buoys and lighthouses, coastal features such as rocks and shoals, as well as other important details necessary for plotting accurate courses.
