required to give the whistle signal prescribed in Rule 34(d) and is
permitted to take action to avoid collision by her mancuvre alone, but a
power-driven vessel must not alter course to port to avoid another power-
driven vessel crossing from her own port side. The give-way vessel is not
relieved of her obligation to keep out of the way.
4. When collision cannot be avoided by the give-way vessel alone
the stand-on vessel is required to take such action as will best aid to
avoid collision.

The distances at which the various stages begin to apply will vary
considerably. They will be much greater for high speed vessels
involved in a fine crossing situation. For a crossing situation involv-
ing two power-driven vessels in the open sea it is suggested that the
outer limit of the second stage might be of the order of 5 to 8 miles
and that the outer limit for the third stage would be about 2 to 3 miles.
