An "express boat" service was started on the Glasgow, Paisley and Ardrossan Canal in 1830. One of its employees, William Houston, was guiding an empty horse-drawn boat when the horse took fright and bolted. Expecting the horse soon to tire, he hung on, but was amazed when the boat rose up onto its bow wave and shot off along the canal at high speed. Mr Houston was canny enough to realise the potential, and soon travellers were being hauled along the canals at high speed in an early example of planing.
