A trimaran is a type of boat that features three hulls: one main hull and two smaller outrigger hulls on either side. This design provides greater stability and speed compared to traditional monohull boats. Trimaran vessels are often used for sailing, racing, and recreational purposes due to their efficient performance on the water. The trimaran's unique structure allows it to glide smoothly over waves, making it popular among sailors and adventurers. Many modern yachts and sailing competitions utilize trimarans for their advantages in speed and stability, showcasing their versatility in various marine activities.
