It is most difficult to consider what one would have done at that time as a professional Master Mariner in todays modern day with all our sophisticated equipment..

To me applying a great deal of hind sight I would ask my self :- would I have sailed knowing that the life saving equipment ie the life boat capacity had been reduced. The answer that I would come up with is that I would not have done so. I would also clarify that by saying hat todays rules etc are not the same as in 1912.

My second question that I would ask myself is would I have proceed at the speed the Titanic was going at when it struck the ice berg. Once again the answer has to be that from lessons leaned and from experience the answer is no I would not.

I will address your mail question would I have gone down with the ship, No I would not. Rhis is a Victorian myth which j[has bee amplified by Hollywood. What we do is our best to save and protect our passengers , ship and crew, but at the end of the day not at the futile expense of our own lifes.

It might help to know whether this engine had been running okay until recently, or if it was in storage for some time and now you're trying to start it. If it had been running up until recently, I'd say it's worth troubleshooting yourself. If this is some sort of resurrection, chances are the problem is more serious and will need professional work.
