  1. What is apparent wind? Apparent wind is what the Maretron WSO100 measures and doesn't necessarily reflect what the wind is truly doing. For example, if the vessel was moving at exactly 5 knots and the wind was blowing in the exact opposite direction at 5 knots, then t... Read More
  2. Which Maretron products are necessary in order to display apparent wind? In order to display apparent wind, you only need a WSO100 and a display capable of showing apparent wind. Maretron's DSM150/250 dedicated NMEA 2000 displays or Maretron's N2KView PC software are capable of displaying apparent wind.... Read More
  3. How do I display the WSO100 apparent wind on Maretron’s DSM150, DSM200, or DSM250 display? You display the WSO100 apparent wind on a DSM150, DSM200, or DSM250 in the following way.Enter menu mode, scroll to "Favorite Screen Setup..." and press < Enter >Scroll to the favorite screen where you would like to view the apparent wind and press <...

  4. What is true wind? True wind is what the wind is truly doing and it can be computed from the measured apparent wind by subtracting the vessels speed. For example, if the vessel was moving at exactly 5 knots and the wind was blowing in the exact opposite direction at 5 ... Read More
  5. What is ground wind? Ground wind is the speed and direction of the wind referenced to a compass rose, which is different from apparent and true wind which are referenced to the bow of the boat. The apparent and true wind are interesting to see how the wind is affecting o... Read More
  6. What is the difference between true wind referenced to ground speed and true wind referenced to water speed? True wind is computed by subtracting the vessel speed from the apparent wind. The vessel speed is either referenced to the water (Speed Through Water (STW)) or the vessel speed is referenced to the ground (Speed Over Ground (SOG)). If the STW is subt... Read More
  7. Which Maretron products are necessary in order to display true wind referenced to water speed? In order to display true wind referenced to water speed, you will need a WSO100, a DST110, and a display capable of computing true wind referenced to water speed. The WSO100 measures the apparent wind while the DST110 provides Speed Through Water (ST... Read More
  8. Which Maretron products are required for me to display true wind referenced to ground speed? In order to display true wind referenced to ground speed you will need a WSO100, a GPS200, a SSC200, and a display capable of computing true wind referenced to ground speed. The WSO100 measures the apparent wind while the GPS200 provides Speed Over G... Read More
  9. Which Maretron products are necessary in order to display ground wind? Several Maretron products are necessary in order to display ground wind. You will need a SSC200 compass, WSO100, and a GPS200.... Read More
  10. Why is the WSO100 wind direction incorrectly displayed on my display? The WSO100 will not show the correct wind direction if it hasn't been aligned with the boat. You align the WSO100 in one of two ways:align the post (there are three posts attaching the top of the WSO100 to the base) closest to the humidity senso... Read More
