Senator LYNCH (Western Australia) - I should like to have an assurance from the Minister that the classes of ship it is intended to exempt are those which can be steered by their own machinery In the event of a mishap, that is, twin or triple screw steamers. No matter how powerful the engines of a steamer may be, if the rudder body carries away, they would never save her. If the Minister can give the assurance for which I have asked, I think that the amended clause will meet the situation very well.
