A trimaran is a type of multi-hulled boat that features three parallel hulls. The central hull is typically larger, while the two outer hulls, or amas, provide stability and reduce drag. This design allows trimarans to sail faster and more efficiently than traditional monohull boats, making them popular for both recreational sailing and competitive racing. Trimarans can vary in size, from small sailing dinghies to large ocean-going vessels. They are known for their stability, which is beneficial in rough waters. Many trimarans are equipped with sails, and some are powered by engines, making them versatile for different types of maritime activities.
