Monda Pasta Ship
The brand Monda is selling pasta. In this campaign they are using the rope as a pasta wisp that is sucked up by a head painted on the ship. This looks very funny and attracts attention. The question you can ask is: is your target group in this harbour? The location of your guerrilla campaign is important. It is  also possible to make a picture of the marketing campaign and use the internet to do the rest. This can also work.
