Why Changing Simrad Cruise 9 from MPH to Knots Is Necessary

I found that changing my Simrad Cruise 9 from MPH to knots is necessary because knots are the standard unit used in boating and marine navigation. When I’m out on the water, using knots makes it much easier for me to read speed, compare charts, and understand navigation data the same way other boaters and marine systems do.

My experience is that knots also give me a more accurate and practical sense of speed on the water. Since nautical charts, GPS readings, and most marine instruments are designed around knots, switching from MPH helps me avoid confusion and keeps my boating information consistent. That consistency makes my trips safer and my navigation much smoother.

I also prefer knots because they help me communicate better with other boaters and marine professionals. When everyone is using the same unit, I can make faster decisions, follow route plans more easily, and stay aligned with standard marine practice.
