Introducing 'Cruiser' of and a novel method of construction
BY P. N. THOMAS
One day some work was carried out in the office where I work and I saw the joiners using what I thought were expanded polystyrene foam blocks for partitioning. A friend whose hobby was model aircraft had told me about polystyrene wings and I thought I would try some of this 'Purlboard' for a hull. The Purlboard is 2in. thick including the cardboard outer layers and, as I found later, is actually polyurethane foam - this is important, as it is not affected by glass fibre resin and needs no protection against it. It carves easily with a sharp knife, but you must keep sharpening the knife from time to time as it blunts quite quickly. It also sandpapers very easily so little pressure must be used.
The Cruiser was typical of the screw tug of her day, a narrow hull with little sheer, a 'hollow' entry to give her speed, and bulwarks with very little tumblehome. The funnel was long and thin with a rake that is a bit startling by today's standards. The rake was decreased later — because, it is said, in a following wind the smoke would blow back down the funnel. One or two features were unusual. Tugs generally had 'deadening' above the living quarters, either wood planking or linoleum, and this is absent.
