During a recent bareboat charter we enterred a small mud bottomed inlet during low tide to anchor for the night. The tide charts showed a 1.6 foot change from low to high tide which was ideal for our planned departure the next morning.

The depth sounder showed about three and a half to four feet going in at low tide ... and ten to twelve feet going out the next morning. I wondered if the tide chart might be in fathoms (it wasn't). It sure was more than 1.6 feet change, though. Does anyone have a good explanation for the difference?

Where and exactly when? What weather conditions and storm systems were in the region?

Don't know where you were... or what the tide chart looked like...
but on the West Coast there are two sets of high/low tides.

One set (the minor tides) has a lot less differential between the high and low.

Only things I can guess is that you were looking at the minor tides or there was a large storm or wind induced tide. (??)

Are you sure you checked the right date for the tide? What was the location of the reference data measurement location in respect to the location of the inlet? Did you do the conversions for height and time
for the inlet location? Did the inlet have a creek or river running into it? If so, high tide might be higher than on the coast. Was the inlet narrow in relation to 'outside?' There are a variety of variables to consider.
