Key Takeaways:
- Chart Plotters Do Not Print: Marine chart plotters are display and navigation devices, not printers. Charts need a separate printing solution.
- Laser Printers are the Answer: TerraSlate's waterproof paper is compatible with standard laser printers and professional digital presses for marine chart printing.
- Built for Open Water: TerraSlate's synthetic paper is 100% waterproof, rip-proof, and fade-resistant, making it the right substrate for nautical charts used in harsh marine conditions.
A chart plotter on a vessel shows exactly where you are. What it cannot do is print the chart you need to bring on deck. That confusion is common, and it leads navigators, charter operators, and boating professionals to the right follow-up question: how do you actually get a waterproof marine chart printed and ready for open-water use?
TerraSlate produces waterproof, rip-proof synthetic paper used by tens of thousands of professionals worldwide, including the U.S. Military. The paper line is engineered specifically for environments where moisture, handling, and exposure are constant.
In this article, we’ll examine what a marine chart plotter actually does, how waterproof paper chart plotter printing works in practice, and which TerraSlate paper options are built to handle marine conditions.
What a Marine Chart Plotter Does and Does Not Do
Understanding this question starts with knowing what a chart plotter is designed for. The confusion between chart plotters and printing is common enough that it deserves a direct answer before anything else.
Chart Plotters are Navigation Displays
A marine chart plotter is an electronic navigation device that displays digital charts on a screen. It integrates GPS positioning to show a vessel's real-time location overlaid on a nautical chart. The underlying data these systems draw from is explained in detail on the NOAA electronic chart data page. Their function is entirely display-based.
Chart Plotters Do Not Have Print Capability
Chart plotters do not include print functionality, are not connected to printers, and do not output physical documents. Physical backup charts require a separate workflow involving a computer, a chart file, and a printer.
Why Physical Backup Charts Still Matter
Despite widespread electronic navigation, physical charts remain critical for marine safety. Electronics fail, screens crack, and batteries die. A physical waterproof chart requires no power, has no navigation interface, and remains readable even if the vessel takes on water. Many maritime safety protocols still require printed backups on board, as outlined in the Coast Guard navigation rules governing chart carriage for U.S. vessels.
The Right Question to Ask
The right question is not whether you can print with a marine chart plotter, but which waterproof printer paper and printer combination produces a chart that holds up on the water.
Why Waterproof Paper Is the Right Substrate for Marine Charts
Marine environments are among the most demanding conditions any printed document will face. Standard paper and laminated charts both fail quickly in these conditions, which is exactly the problem waterproof paper chart plotter printing workflows are designed to solve.
The Problem with Standard Paper and Lamination
Standard paper absorbs moisture and degrades rapidly in spray, humidity, and rain. Laminated charts carry their own failure points. Lamination clouds up over time, can delaminate and bubble under repeated exposure, and cannot be folded, making on-deck storage and use cumbersome.
How Synthetic Waterproof Paper Performs on the Water
TerraSlate's waterproof paper is built from military-grade polymers. Each sheet is 100% waterproof, rip-proof, and resistant to grease, UV exposure, and extreme temperatures. The paper can be submerged without cracking, peeling, or delaminating. Toner holds its vibrancy under UV exposure and wet-hand contact, keeping navigation details sharp and legible throughout a full trip.
Foldability and On-Deck Usability
TerraSlate's synthetic paper can be folded, hole-punched, scored, and cut while remaining fully waterproof. A chart can be folded to a manageable size, stored in a dry bag, and pulled out for reference without losing structural integrity.
Thickness Options for Marine Use
For chart table and deck use, 10 Mil at 120lb Cover is well-suited. For lightweight carry, 8 Mil at 80lb Cover balances durability and packability. Both are 100% waterproof and laser compatible.
How to Actually Print Waterproof Marine Charts
Since the chart plotter itself is not part of the printing process, here is exactly how marine chart printing works in practice.
- Source the Chart File: Nautical chart files in PDF format are available from NOAA nautical charts for U.S. coastal and inland waters. These files can be downloaded and prepared for printing at the correct scale and size.
- Choose the Right Paper Size: TerraSlate's waterproof paper is available in sizes including 8.5" x 11", 8.5" x 14", 11" x 17", 12" x 18", and 13" x 19". Larger formats like 11" x 17" and 12" x 18" suit regional charts covering extended routes or offshore navigation where more visual space improves clarity.
- Use a Laser Printer or Professional Press: TerraSlate's waterproof paper is compatible with standard laser printers and copy machines. For full guidance, see our resource on printing on waterproof paper. No special inks or coatings are required. For high-volume or precision printing, TerraSlate's professional printing service uses ultra-high-end digital presses with industry-leading turnaround time and free overnight shipping on all U.S. orders.
- Handle and Store Without Lamination: Once printed, the chart needs no further treatment. Toner fuses directly to the surface and becomes waterproof immediately. Charts can be folded, rolled, or stored flat and will hold up through an entire voyage without degrading.
The process replaces an old workflow of printing on standard paper and then laminating, which adds cost and time and results in a product that ultimately fails in the marine environment.
TerraSlate Paper Options for Marine Chart Printing
TerraSlate offers a range of paper thicknesses in multiple sizes, all suitable for marine chart printing depending on the specific use case.
8 Mil for Portable Navigation
At 80lb Cover equivalent, 8 Mil delivers the right balance of durability and flexibility for charts that need to fold down and travel in a pack, dry bag, or jacket pocket. It reliably handles wet hands and repeated folding in standard desktop laser printers.
10 Mil for Chart Table and Deck Use
At 120lb Cover equivalent, 10 Mil adds the body and structure suited for charts spread across a chart table or stored flat on deck. Value-oriented PolySlate is also available in 10 Mil for operations where cost efficiency and waterproof performance matter.
Professional Printing for Larger Format Charts
For larger formats such as 11" x 17", 12" x 18", or 13" x 19", browse our best waterproof paper for map printing collection, or use TerraSlate's professional printing service for G7-certified color accuracy on commercial digital presses.
Final Thoughts
A marine chart plotter is a navigation tool, not a printing device. Getting a reliable physical chart for open-water use requires waterproof paper and the right printer, which is a separate, straightforward process.
TerraSlate's waterproof, rip-proof synthetic paper is purpose-built for exactly these conditions. Resistant to water, UV, and constant handling, it keeps every printed detail legible from departure to return.
