Then, next important item in this is the water plane area, water plane curve, load water plane,
LWL curve. We have seen the sectional area curve, we have already discussed the role of half
angle of entrance in the class when we discussed wave making resistance- do you remember,
half angle of entrance, we talked about that, that determines how smoothly the hull is going
into water and what will be the wave crest. So, LWL, if it is smooth at fp, if this angle is
small, half angle of entrance is small, then it is always advantages and therefore, this follows
for our curve 2, you see the curve 2 that we showed before, though it has a prominent
shoulder this sectional area curve here has narrowed, which leads to a finer angle of entrance.
