Imray App Discrepancy

[Limecc]

Can anyone explain why the numbers in the table compared to the chart are not the same at high and low water please? Thanks.

Looks like there’s a 0.3m offset applied, is this an app setting for vessel draught?

..or something to do with offsets for standard ports.

Knew there had to be a simple explanation. It was defaulted to 1.8m draft but the real reason was you slide the horizontal bar up and down and calibrate, the table is always true. I removed the preset draft in settings and set the datum bar on the chart to zero by swiping each side of the screen up or down and now is as expected.

I'd already selected the nearest local port and there's an option to add your own custom port but yes good call. It sometimes defaulted to Dover and then you get an entirely wrong set of figures. Have to keep an eye on that.
