Video: F/V Southern Wind, St.Paul AK

Look at the St Paul Island in NOAA’s online chart-viewer >>> Chart 16382
Zoom into the port inset in the right bottom of the chart.

There, you can see that you cannot pass the port entry backwards and then reverse to forward to enter into the port. There is not enough water; only about 3 meters with these enormous waves…

It seems, you need a lot of power, for speed and for rudder efficiency, to be able to enter straight away. Look at the black smoke coming out of the boat, sometimes.
