*In an Arctic Class 1 ship, only that part of

(a) the bow area and stern area lying between the horizontal projections of the upper and lower edges of the mid-body area need be considered; and

(b) the mid-body area forward of amidships need be considered.

**In an Arctic Class 1 ship, ice pressure need not be considered as a factor in the design of the hull in the lower bow area, lower transition area and upper transition area, and the strength standards usually applied to ocean-going ships shall apply in these areas.

NOTE: The loading values shown in this Table are based upon a stringer or web frame spacing of 1.2 m. For any other spacing, these loading values shall be increased or decreased, respectively, in direct proportion to the amount that the actual spacing is greater than or less than 1.2 m.

*In an Arctic Class 1 ship, ice loads need not be considered as a factor in the design of the hull in the mid-body area and stern area, and the strength standards usually applied to ocean-going ships shall apply in these areas.
