Hi Bill,

I don’t agree with your statement you can do without a STW sensor if you are not racing. In my current location (Caribbean) this may be OK but my former cruising grounds (Western-Europe) it would be quite an omission to live without STW. When tidal currents are getting significant you really appreciate the information you get from the difference between SOG and STW. We’ve sailed in places where the tidal current can run up to 8 knots. You really want to know when the tide change.
So it’s very depending on your cruising grounds if you can do without a STW sensor.
