Why Tugboats Use Kort Nozzles

Most ships use open propellers, but tugboats need enormous thrust at almost zero speed. Their propellers have limited space, yet may be asked to push, pull, or hold a ship far larger than themselves.
That is why many tugs use a ring-like duct around the propeller: it is built for pulling power, not top speed.
