A motorboat is a boat powered by an engine rather than sails, oars, or paddles. Unlike sailboats that depend on wind or rowboats that need muscle power, motorboats use gasoline or diesel engines to propel themselves through water. They range from small fishing boats puttering across a lake to sleek speedboats that race across open water.

The invention of motorboats in the late 1800s changed boating. Suddenly, people could travel on water without waiting for favorable winds or exhausting themselves rowing. Motorboats made water travel more reliable and practical: fishermen could reach better fishing spots, rescuers could respond to emergencies faster, and families could explore waterways more easily.

As a verb, motorboat means to travel by motorboat.

Today you'll see motorboats everywhere water recreation happens: at marinas, on rivers, and across lakes. Some are designed for fishing, with special seats and storage for equipment. Others are built for speed and water sports like waterskiing. Coast Guard vessels use powerful motorboats for rescues and patrols.
