I have depth display in feet (as all good seaman should have) , but shows tenths of a foot ! Work that one out - not sure yamaha get the idea of imperial measurements !
One of the never ending British quirks - we say out boat is XYZ Metres, we go at knt, for miles , with horsepower on a boat that weighs a certain number of kilos (for our trailers with 10 inch wheels) use litres per hour of petrol (worring about it being more then £5 a gallon) , looking at charts in meters depth of water , on a bearing of whatever ( true ? magnetic ? chart ? ). all so we can get back to marinas that charge you by the lenghtof you boat (in feet ! )
No wonder I ignore most of the numbers.
