What's the point of nautical maps?

I'm curios, what's the point of nautical maps? It's open water, people can just sail straight in the direction they want to. What's the point?

It's easy to think of the ocean as just a big, empty space, but it's actually full of features, both visible and invisible, that can be a big hazard to a vessel. Nautical maps or charts provide crucial information than on can think of. They show things like water depth, which is probably the most critical bit of info coz you don't want to run aground in shallow water, especially if your ship has a deep draft. They also mark the location of submerged rocks, reefs, and shipwrecks that aren't visible from the surface but can tear a hole in a hull. Beyond just hazards, charts also show navigation aids like buoys, lighthouses, and day markers that help sailors figure out their position and stay on a safe course, especially at night or in bad weather. They also show things like shipping lanes, anchorage areas, and even the direction of currents. So, while you can technically "sail straight," you're much safer and more efficient with a chart guiding you around all the potential dangers and along the most efficient routes. It's basically the road map for the sea!
