I am trying to learn the Mingulay Boat Song and I am confused about some of the lyrics.

In the second verse the song goes...

What care we though, white the Minch is? What care we for wind or weather?

In some versions I have also seen it as

What care we how wild the Minch is. What care we for windy weather.

Ok does anyone know what a Minch is? Which version makes sense???

Thanks Jim in Silver Spring.
