Speedometers show the boat's speed relative to the water — information that differs from GPS speed due to the influence of current and wind, and is therefore especially valuable to sailors in assessing the success of trimming. Wema offers GPS-based speedometers in several measurement ranges: a 30 knot meter with a white/RST frame, a 60 knot meter in both black and white, a 15 knot meter in black/RST, and a separate 0-30 knot model in white. In addition, the range includes the Wema MFG 3" NMEA2000 touchscreen display, which can display speed as part of a larger instrument cluster.

It is worth choosing the measurement range according to the boat's realistic top speed — for a slower sailboat, a 15 or 30 knot scale is sufficient, so that the needle movement is more accurately displayed in the normal speed range, while for a faster motorboat, a 60 knot gauge is needed so that the entire operating range fits on the scale without the needle being at the extreme end.

The GPS-based meter measures speed using satellite positioning, making it easier to install than a traditional log sensor-based system — no frame penetration is required for the sensor. The choice of frame color (black or white) is made according to the look of the rest of the control panel to achieve a unified whole.

The accuracy of a GPS-based speedometer depends on the quality of the satellite signal, which can be reduced, for example, in a dense archipelago when the signal is obscured by high rocks or terrain — this is worth considering if the meter occasionally shows inaccurate or jumpy readings in narrow waterways. Unlike a log sensor-based meter, GPS speed measures speed relative to the ground, not the water, which means that the current affects the reading — this difference is good to be aware of, especially in navigation, where speed relative to the water would give a more accurate picture of the boat's actual progress in the water. The choice of scale of the meter affects the accuracy of the reading in practice: a scale that is too wide relative to the boat's actual speed makes small speed changes difficult to detect from the needle movement, while a properly sized scale shows the changes clearly. A touchscreen connected to the NMEA2000 network allows speed data to be combined with other meters on the same screen, which saves space on the control panel compared to several separate analog meters.

After installing the meter, it is recommended to calibrate the display according to the manufacturer's instructions so that the reading corresponds as closely as possible to the actual speed of the boat.

The right gauge type and scale make it easier to accurately monitor speed throughout the sailing season in a variety of conditions.

Regular inspection and proper calibration of the meter will ensure reliable speed information throughout the sailing season.
