Also works fine in an Aluminum hull

In spite of the guidance that it only works in a GRP hull, we installed it in our Aluminum hull and it turns out to work fine. Of course when there is fouling the speed reads a little slower (more so than the SOG), but this is a good reminder to dive and clean the hull, and unlike those stupid paddlewheels a stiff brush is all you need for it to read cleanly again!

Interesting technology

Replaces the ever-clogging wheel with the log giver.

good thing

While not completely resistant to fouling, it's significantly better than the usual dials.

A disadvantage is that the system displays noticeably different speeds when the water flow isn't straight. On the starboard tack, my boat is half a knot "faster" than on the port tack (at the same GPS speed). I suspect this is because the water flows differently around the sensor in each direction.
