ASD (Azimuth Stern Drive) tugs are currently one of the most popular tug types on the market.

With two azimuth thrusters at the stern of the tug and a box keel from the bow to approximately amidships they proved a very manoeuvrable and powerful tool, whilst operating on a relatively shallow draft. They are particularly good for towing over the bow but can also tow over the stern.
