Do you use statute miles and mph or nautical miles and knots?

Simple poll on statute miles and mph vs nautical miles and knots.

Knots and nautical miles when offshore.

Statute miles when in the ICW and inland rivers.

Nautical miles and knots.

Some and particularly smaller boats around here use kilometers and KPH.

Always use knots and NM on our Sea Ray. Always use miles and mph on our Whalers because they're on lakes and rivers with no long distances involved.

Both. Depends on cruising area and what the charts say.

Me too: Knots and nautical miles when offshore. Statute miles when in the ICW and inland rivers.

However all charts here are in meters, but I still set depth sounders to feet. Habits.

I set all my navigation tools to knots and NM, but mentally convert to Statute sometimes on the ICW.... and when I am calculating fuel mileage per gallon!

Knots and NM under normal conditions; MPH and SM when the "current" chart uses those instead.

Fuel mileage for me is always nmpg or gpnm.

Nautical miles and knots, both off shore and in inland waters. I established my approach to navigation and stuck with it, fearing that I would get confused if I switched back and forth.

No...that wasn't part of the initial discussion. However, km/h would fit in the statute miles selection as it is statute based and not nautical based.

Knots off shore and statute miles on the ICW, because ICW mile markers are posted in statute miles. Makes computations easier.

All the guide books list distances on the ICW in SM and locations as SM from MM 0, so it's much easier to just convert to SM if you're going North or South on the ICW. Everything else KM but does it really matter?

Doesn't matter one tiny bit other than keeping it straight between watches if info is passed and misinterpreted.
