Windage Areas

If you have entered a valid set of profile points, then Calc has the facility to calculate the windage areas and heeling arms at a number of draughts.

You must define an initial draught, a final draught and an increment. Obviously, the increment should be greater than zero and the final draught should be greater than the initial draught.

For each draught, the area and centre of area are calculated from the profile for both the segments above and below the waterline.
