Ahoy,
My very low-tech water tank gauge is a sticky note on the chart table.Ā Three columns.Ā Forward, Center, Aft.Ā Under each column is either Full, In Use or Empty.Ā Works great!

To my surprise, the 355 has 3 separateĀ water tanks but no gaugeĀ to determine water levels. Had these installed. One guageĀ measures 2 separateĀ tanks, the other 1. In case there is an interest to do so on your boats....

Related, I donāt rely on my fuel gauge.Ā It registers as Full when there is only 10-12 gallons remaining and the tank holds 30.Ā Ā Using Excel, I add the fuel used on my Yanmar 3YM30 29 HP at 0.75 gallons/hour assumed running at 2500 RPM, and fuel used on my Panda 4 kw at 0.33 gallons/hour.Ā It turns out to be pretty close but slightly on the conservative side when I refuel.Ā It provides a good measure of peace of mind.

Nice gauges!
Iāve not heard of a lot of sailors keeping all potable water valves open at once. Thatās undoing the most reliable āgaugeā of all; running dry. By cycling one tank valve at a time, weāll always have a zero tech method of knowing, at a minimum, whatās left. Donāt get me wrong, I like tech and might consider these tank monitor aids. But I wonāt ever keep all 3 valves open and rely solely on the monitors. Captains of the boats I work on would keelhaul me if I did this. They want to know for certain what we have on hand and rarely completely trust their gauges.
Ā
To keep the all the plumbing routinely in use and water fresh(er), I rotate through each tank sequentially as one runs empty.Ā Redundancy, especially when convenient, should always be pursued in my mind, but as always, to each his own Sir.
Ā
Fair winds!

Bill, great it works for you. Sometimes the simplest approach is the best one. I appreciate the sticky notes butā¦ā¦wanted a a little bit more techš.
P.S. I keep all 3 tank valves open.
