Smooth curve hull
Smooth curve hulls are hulls that are rounded and don't 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.
- 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.
