I seem to recall that the problems with the previous tugs concerned them not achieving the required bollard pull. Rumour has it that the problems with the current new tugs concerns handling and reliability, which is a much more serious problem for those who crew them. When supposed to be going in a straight line the tugs are crabbing like a yacht making leeway, and what is worse this crabbing can flop from one side to the other. When on the bow line the last thing wanted is a loss of control or a blackout, which can easily result in the loss of tug and more importantly the crew. It appears that luckily in this case the tug was close under the bow and about to let go the line at the time the problem occurred. Sella Ness have already gone on record stating that there is nothing wrong with the tugs so it would be rather optimistic to expect the yard to accept a change of hart now and meet any costs. I also hear that Sella Ness have decided that the bulbous bow is the problem although others feel the skeg is a more likely option. Roger Moore has stated that there is no evidence of mechanical failure, is he splitting hairs and differentiating mechanical from electronic, or implying that the crew were at fault?
