The Long, the Tall and the Short

This was the name of a play by Willis Hall, made into a black and white film, about jungle warfare during WW2. It struck me as being a good description for these contrasting vessels. 'Lord of the Glens,' looks imperious to the left while the 'Loch Ness' houseboat looks appropriately indifferent. 'Size isn't everything,' I can hear her say.
