Four-oared shells are a type of rowing boat designed for four rowers, each using a single oar. These boats are typically long and narrow, allowing for efficient movement through the water. They are commonly used in competitive rowing, where speed and teamwork are essential. The design of four-oared shells promotes balance and stability, making them suitable for both beginners and experienced rowers. Rowers sit in a staggered position, which helps distribute weight evenly. This type of shell is often seen in events organized by organizations like FISA (the International Rowing Federation) during regattas and competitions.
