Savvy navvy supports both imperial and metric measurement units. Here's how to toggle between the two.
Login to your savvy navvy account. Once you're in the app click on the three "dashes" or lines on the top left of your screen as shown here.
Once you click on the three lines you will see a screen with a bunch of options, click "boat settings".
When in boat setting you will see, as standard, your waterline length, minimum depth and bridge height clearance displayed in metres.
To change metres to feet click on the word "metres" and you will see the numbers and units change, like this.
We hope this makes sense, but if you have any further questions please get in touch with our team as we're happy to help!
