  1. I navigate using true heading and not magnetic heading; how do I use the SSC200 compass and N2KView software to view my heading in true? The SSC200 compass outputs heading information in magnetic form and before N2KView can display true heading, the variation must be known. One source of variation is the Maretron GPS antenna/receiver (GPS200). If an SSC200 and GPS200 are connected tog... Read More
  2. 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
  3. 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
  4. 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
  5. 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
  6. How do I display the WSO100 true wind referenced to water speed on Maretron’s DSM150, DSM200, or DSM250 display? You display the WSO100 true 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 true wind and press  < Enter ...

  7. How do I display the WSO100 true wind referenced to ground speed on Maretron’s DSM150, DSM200, or DSM250 display? You display the WSO100 true 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 true wind and press < Enter >...

  8. Why doesn’t the SSC200 compass transmit true heading? The SSC200 is a magnetic compass, which means that it measures the direction of Earth's magnetic field relative to the magnetic poles (magnetic heading). This is different than a gyrocompass, which measures heading relative to the Earth's r... Read More
  9. I navigate using magnetic heading and not true heading; how do I use the SSC200 compass and N2KView software to view my heading in magnetic? The SSC200 compass outputs heading information in magnetic format, so you need to properly configure N2KView to display heading in magnetic. To view magnetic heading within N2KView, click on the "Units Setup" tab, and select "Magnetic from the "Headi... Read More
  10. I navigate using magnetic heading and not true heading; how do I use the SSC200 compass and Maretron’s DSM150, DSM200, or DSM250 display to view my heading in magnetic? The SSC200 compass outputs heading information in magnetic format, so you just need to properly configure the DSM150, DSM200, or DSM250 to display heading in magnetic. To view magnetic heading on the DSM150, DSM200, or DSM250, do the following:Enter ... Read More
