Ship bottom form

Abstract From the Canadian patent

The invention relates to a ship intended for operation in icy waters, the hull of which comprise a generally horizontal bottom part and a bow portion that breaks ice downwardly. In order to achieve an effective guiding of broken ice chunks to the sides without increasing the draught of the ship noticeably and without impairing its seaworthiness at least, two but preferably three or more list-like guiding elements are arranged one after another on the bottom part of the ship on both sides of the centre line, which elements are obliquely arranged with regard to the centre line.
