Why I Needed to Change My Simrad Cruise 9 from MPH to Knots

When I first started using my Simrad Cruise 9, the default speed setting was in miles per hour (mph). While that made sense for some land-based activities, I quickly realized it wasn’t ideal for my boating needs. Since nautical navigation relies heavily on knots, having the display in mph made it harder for me to interpret speed and distance accurately. Changing the units to knots gave me a more intuitive understanding of my boat’s performance and helped me communicate better with other mariners.

Another reason I found the switch necessary is that most marine charts, weather reports, and navigation aids use knots as the standard speed unit. Sticking with mph created unnecessary confusion and increased the risk of miscalculations when plotting courses or estimating travel times. By changing my Simrad Cruise 9 to knots, I aligned all my instruments and references, which improved my overall safety and confidence on the water.

Finally, using knots feels more professional and authentic when I’m out at sea. It’s a small change, but it makes a big difference in how I experience navigation. It also helps me stay consistent with boating terminology and practices, which is especially important when sharing information with other sailors

My Buying Guides on Simrad Cruise 9 Change From Mph Toknts

When I first got my Simrad Cruise 9, one of the things I wanted to customize was the speed units—specifically changing from mph (miles per hour) to knots. If you’re like me and prefer nautical units for a more accurate boating experience, here’s what I learned and how I approached it.

Understanding Why Change Units from Mph to Knots

I realized that while mph is common for land vehicles, knots are the standard for marine navigation. Knots give a better sense of speed over water, and using them makes interpreting charts and weather information much easier. If you’re navigating coastal waters or offshore, switching to knots is definitely the way to go.

Checking Compatibility and Software Version

Before trying to change the units, I made sure my Simrad Cruise 9 was running the latest software. Sometimes, older firmware versions don’t offer full customization or have different menu layouts. I recommend checking Simrad’s official website or using their update tool to ensure you have the latest version installed.

Step-by-Step: How I Changed Units from Mph to Knots

  1. Power on the Simrad Cruise 9 and access the main menu.
  2. Navigate to the Settings or System tab—this is where unit preferences are usually found.
  3. Find the Units or Display Units option.
  4. Select the speed unit and change it from mph to knots.
  5. Confirm the change and exit the menu.

After this, all speed readings on my Cruise 9 showed in knots, which felt much more intuitive for my boating needs.

Things to Keep in Mind

  • Sometimes the unit change affects only speed readings, while other measurements like distance or depth may need to be changed separately.
  • If you don’t see the option to change units, it might be hidden in an advanced menu or require a software update.
  • Refer to the user manual or Simrad’s online support for model-specific instructions.

Why I Recommend Customizing Units on Your Simrad Cruise 9

Making this simple change improved my navigation experience significantly. Using knots aligned the display with nautical charts and weather reports, reducing confusion during trips. It’s a small tweak that enhances safety and convenience on the water.

Final Thoughts

If you’re setting up your Simrad Cruise 9 or want to personalize it for marine use, changing from mph to knots is a straightforward but important step. Just follow the menu options, keep your software up to date, and enjoy a more seamless boating experience. Hopefully, my guide helps you get there quickly and easily!
