Smooth curve hulls are
hulls that are rounded and do not usually have any
chines or corners. They can be
moulded, round-
bilged or soft-chined. Examples are the round bilge, semi-round bilge and s-bottom hull.
Characteristics
The round bilge hull is the most commonly used hull form as the shape promotes planing and has other good properties as well.
The S-bottom hull allows relative comfort on the boat, as the shape reduces the rolling movement on the boat.
