When talking to people from the industry explaining what a tug is and what it does is never very difficult.
It gets a bit more difficult trying to explain tugs and towage to someone on 'the outside'. Tugs exist in many forms but they all share a common goal, the art of towing an object.
As we all know pictures say more than a thousand words so we have made a small selection of images depicting a tug/towage.
Tug of War
Really, this sounds more menacing than it is. Tug of war, tug o' war, or tug war, also known as rope pulling, is a sport that directly puts two teams against each other in a test of strength.
