Sea Shepherds skib, Stewe Irwin, forsøger at torpedere Kaiko Maru anden juledag, efter at have overdænget hvalfangerskibet med flasker indeholdende smørsyre, samt ukendte kemikalier. Her er en beskrivelse af begivenheden fra IRC's website:
"The Dutch vessel “Steve Irwin” last night (26 December) committed an attack against the Japanese sighting vessel Kaiko Maru, currently engaged in whale research in the Antarctic.Det er selvfølgelig dybt uforsvarligt at torpedere et skib i et ishav, og det viser tydeligt Sea Shepherds ekstreme foragt for menneskeliv. Der er ikke tale om fredelige miljøaktivister. På videoen kan man se hvorledes de forsøger at torpedere hvalfangerskibet:
Protesters from the Steve Irwin threw bottles of acid and bottles containing a bluish-green liquid at and onto the Japanese vessel. The Steve Irwin rammed the Kaiko Maru from the starboard rear side and spent a number of hours in dangerous close-quarter harassment of the Japanese vessel, repeatedly overtaking and circling the Kaiko Maru.
The incident occurred when the Kaiko Maru was undertaking a detour in the ice pack area after completing the day’s research activities. The weather had deteriorated and fog had reduced visibility conditions to about 500m.
The Steve Irwin approached the Kaiko Maru from the starboard rear side and within two minutes the protesters aboard started throwing bottles, approximately 15 bottles of butyric acid.
After the ramming, the Dutch vessel pursued, repeatedly overtook and menacingly turned around the Kaiko Maru for approximately three hours, and thereafter changed course to the east where it disappeared from the Kaiko Maru radar.
The Kaiko Maru topside starboard rear bulwark was damaged by the Dutch vessel’s ramming, although no hindrance to its present operation and research activities has occurred."
