EN = Δ^(2/3) + 2 B H + 0.1 A
Δ = Rule Displacement in MT
B = Rule Breadth in m
H = effective height in m from the summer load waterline to the top of the uppermost deckhouse, measured as follows:
H = a + Σ hi
a = distance in m from the summer load waterline amidships to the upper deck at side (Freeboard)
hi = height in m on the center line of each tier of houses having a breadth greater than B/4. For the lowest tier, hi shall be measured at center line from the upper deck, or from a notional deck line where there is local discontinuity in the upper deck
