The Danish Maritime Authority has now ruled out the possibility of alcohol being the cause of the accident. They say that everything is pointing towards a defect in the Sundstraum's steering gear leaving her unable to manouver.
The Lus failed to carry out any effective evasive action after giving off five short blasts but instead spend the time trying to get the Sundstraum on the radio. So it's going to be a bit interesting to see how they are going to split the blame on this one... Because both ships failed to comply with the colregs, one way or the other!
