Thanks for replies.
Bigal, I think the fairleads are in a good position as they are in the middle of the side benches (it’s a World).
Howard, I hope you’re right. Your post made me calculate a little, and it turns out (if I did it well) that even a current of 0.5 kt (which might have been unnoticable to me then and so regarded as insignificant) widens a theoretical tacking angle of 90 deg to 101 degrees. And it’s quite possible that it was a bit stronger around the headland.
If anyone would find it amusing I’ve attached the illustration that I made.
Thanks and best wishes,
Mato
