Hi group, what wind speed is indicated by a wind vector with 3 full feathers
and one half feather. And can anyone confirm that the ferry crossing from
Rosyth to Zeebrugge is going to be rough on Monday night ?

Thanks

found it, 35knts.

That would be Force 7 on the Beaufort scale, so just below Gale Force 8.
Each full feather represents 2 and a half feather represents 1.

Each full feather represents 2 and a half feather represents 1.

The feathers do not represent Beaufort Forces but units of 5 kn, but by
a happy coincidence it amounts to the same thing for Force 8 (just) and Forces
9 and 10. 50 kn is Force 10 all right but 15 kn is Force 4, not 3.

In that case I owe the questioner an apology. I've been living under
that misapprehension for 30 years or more.

Yes, and 35kn = BF8, not 7.
