Beaufort

When I take the boat out I have learned to check a weather page. There it talks about bft, which I had no idea what it was about until I googled it.

I have only learned that 1-2 is very good, and above 3 can be tricky with my little engine.

It's a bit like a computer. I have no idea how it works, I just know it does. Well, at least when I can call a friend re the continuous updates I reluctantly receive!
