While the two Telefnica left the field in it wake, PUMA ate into Green Dragon's margin and Ericsson 4 put pressure on puma CAT.
At the second turning mark the two Telefnica boats, Blue and Black, still led. PUMA stole third from Green Dragon as they nipped inside at the mark, followed by Ericsson 4.
Ericsson 3 sailed "through the eye of the needle" between puma basket and Green Dragon as the fleet dropped their spinnakers and flew headsails for the final leg of the course.
As the boats sailed back towards the gate at the start line off Fan Pier, the freighter reappeared and the coastguards ushered the fleet away from it, the drama unfolding right in front of spectators onshore.
The final order as the fleet left Boston and disappeared into the mist between there and Galway, Ireland, was Telefnica Blue, Telefnica Black, PUMA and overall race leader Ericsson 4.
