One thing I've been told by many sailors is that when the outside boat calls for no room and you think it's close you should turn toward them immediately and if you touch then you should protest because you had overlap.

I don't agree with this approach because you should always avoid contact but I've been told this by many seasoned sailors on big boats.

Sometimes people don't understand that the spinnaker counts if it's overlaped against the other boats hull while the hulls are not overlapped.
