When I was seven, I went on that boat. I was stood at the front with my parents, and the captain blasted out on the pa 'would the young man on the bow report to the bridge please?'. I didn't know what to make of this, I think I thought I was going to be told off or something, but we went up there, and he gave me control of the steering for a while.
...actually, now I come to think of it, it might not've been that precise ship, or even Loch Lomond, but your picture triggered the memory straight away, so cheers for that.
