Speed Over the Ground (SOG) is the speed of the vessel relative to the surface of the earth. Speed Through Water (STW) is the speed of the vessel relative to the water. It is possible for the STW to be zero while the SOG is 5 knots, for example if... Read More

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... Read More

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

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 the... Read More

Yes, you can change the direction the elbow points for a 90 degree field attachable connector. When you assemble the field attachable connector, you can adjust the direction in which the elbow points by rotating the insert into one of the four... Read More

No. Maretron's EGT sensor is meant to measure the temperature of the exhaust gas temperature, not the temperature of the exhaust gas after it has been cooled by water. Placing the EGT probe downstream of the riser or elbow will render the device... Read More

The heart of the NMEA2000 system is the cabling infrastructure and it is vital that field connections are made correct to avoid damage to sensors or non-intelligent components such as tees, multi-ports, power-taps. Maretron offers four types of Field... Read More
