Kyle, this is a rather tough one to answer as intership transfers at sea are not the easiest things to do. Even under the best of conditions, they would have had to resort to boat operations which is a time and labour intensive task to say the least...to say nothing of downright dangerous even when the deck is not stacked against you.
And the deck certainly would have been stacked against anyone trying to rescue the 1500 to 1600 people still trapped on the sinking ship.
This is not to say that the attempt wouldn't have been worthwhile. If
the Californian was as close as
Captain Lord's critics assert, it's conceivable that they could have made a difference by fishing swimmers out of the water befor they froze to death. Whether the numbers be one, fifty or a couple of hundred, it would have been a major improvement over zero.
If the ships were as far apart as
Captain Lord's defenders assert, the effort, though futile, still would have spared Captain Lord a lot of public censure.
A couple of links to help you understand the problems. One is an article wrote by Tracy Smith, Erik Wood and myself which was published on ET last September;
A critical analysis of the SS Californian’s role in Titanic’s sinking, reassessing the potential and limits of its rescue capability.
