My depth instrument (autohelm st50) has taken to mostly reading 1.5m, although it occasionally appears to show the right depth, especially in deeper water. The waterline offset is set to 0.7m and predictably with this set to 0 depth is .8m. We only came out of the yard last week so “something sticking out of the keel” is unlikely. The boat had been hardly used in nearly 2 years prior to that so the problem may have predated the yard trip. I’ve checked the connections and wiggling wires has no effect. Next step is anchoring somewhere to swim under the boat and maybe taking some wet and dry (used very wet) to the sensor but anyone seen this before or ideas about resolution? Having the boat lifted again to replace the sensor is going to be awkward
