Venetian gondolas are designed with a deliberate asymmetry to counteract the force of the gondolier's rowing. Because the gondolier stands on the left side of the boat and uses a single oar on the right, the boat would naturally tend to veer to the left with every stroke. To fix this, the left side of the gondola is built approximately 10 inches (24 cm) wider than the right side. This creates a permanent tilt to the right, which acts as a natural rudder. When the gondolier is on board, their weight helps level the boat, but the asymmetrical hull ensures the vessel travels in a straight line without the rower having to constantly change sides. This "leaning" is a hallmark of Venetian engineering, allowing a single person to navigate the narrow, crowded canals with incredible precision using only one oar.
