How is the corrected run of shore determined?

The corrected run of shore is determined by subtracting the width of the strongback. This calculation is necessary because the strongback is a component that can add length to the overall measurement when the true slope or direct measurement of the shore is needed. The strongback acts as a horizontal platform upon which other equipment or supports may rest, and if its width is not subtracted, it would lead to an inaccurate assessment of the effective run of the shore. Therefore, the process ensures that only the relevant length of the shore contributes to the effective run, leading to more precise damage control operations.
