Cast off!

Was leaving a Glasgow dock to sail down the Clyde as the captain of a fairly large vessel (it could have been a car ferry or the like). Very excited about this, and pretty confident, even though I hadn't done anything like it before. I gave orders to cast off at bow and stern - I could hear my crew complying, and the ship began to drift out into the river. I realised with slight concern that I hadn't first ordered the engines to be started (surely I was doing this in the wrong order) and did so. To be quite frank, I was only fleetingly bothered by this, and primarily because I didn't want people viewing from the quay to see I didn't know what I was up to. Once we were under way (at 'half forward' I think), I began to concentrate on the river ahead, knowing that I would have to anticipate any change of course long before we reached the point at which it was required.
