Forebody

Beyond that, there are indications that some gains may be made on road vehicles by shaping the forebody in such a way that the external flow is channeled sideways around the vehicle, rather than over the top, as will be discussed in a later section.

The wear-off is intensified in heavily loaded areas, such as the ice belt in the ship's forebody, and during operations in heavy ice and especially in presence of soil or sand mixed in ice.
