Science and Technology Log
I continue practicing navigation underway using radar and dead reckoning. Three of the fixes I checked fall right on the ship’s course. A few others fall within an acceptable error. The swells were a little rough so I take a break from the radar screen and charts until the late afternoon.
The NOAA Ship RAINIER anchors in Northeast Bight, Nagai Island for the night.
