Shinoussa was outbound loaded with jet fuel at sea-speed,
probably 11 knots or more.
Hellespont Faith was in bound loaded at 8.5 knots.
Both ships were under pilotage.
Chandy N was an integrated tug inbound pushing three barges
loaded with catalytic feedstock doing 5.5 knots.
All three vessels talked to each other.
Faith overtook and passed Chandy N
and then less than a minute later passed Shinoussa,
creating a very crowded situation.
There are conflicting accounts about what happened next.
Cahill accepts the Shinoussa's pilot's story
that he ordered hard starboard to counter
the effect of the Faith, but
the helmsman who spoke very little English
went port, perhaps because the ship was already
on the starboard side of a narrow channel.
Shinoussa hit the aft port end of the second
of the three barges.
Cahill feels strongly that the Faith should
have waited until the Shinoussa was past,
before overtaking the Chandy N.
