Still standard speed but that one knot will get a lot of extra mileage. Narhwal is its own beast, being one of the older boats.

Are you using the "Max Range at current speed" tool on the nav tools bar?

This will easily help you find the ideal speed/range balance for patrols. Just plot out your course and once at desired speed click on the button will display you may range at current speed. Sometimes, going too slow will actually burn more fuel and decrease range.

Also, with the frequent dives, make sure when surface to turn off your batteries, as recharging after every short dive will burn more fuel. Batteries automatically charge as you likely are aware.

I believe Standard speed is 14kt, 2/3 is 10kt, and 1/3 is 7kt. I usually patrol at 5kt.

I use "Max Range at current speed" all of the time. That's how I knew I had enough juice to get to Midway. IJN patrols screwed it for me. I noticed going super slow decreased to range. Go figure.

I actually forgot about turning off the battery recharge until past Marcus.

I reloaded a save and I am about 3610nm for Midway and if I travel at 7kts I have about 4500+ range. We'll see if I make it this time.
