motorboats

Motorboats are vessels powered by an engine, typically using an internal combustion engine or electric motor. They range in size from small runabouts to large pleasure craft and sometimes serve commercial, rescue, or military roles. They are distinguished from sailboats, which rely on wind power.

Propulsion is provided by outboard motors mounted on the stern, inboard engines connected to a propeller shaft, or stern drives that combine an inboard engine with an outboard-like drive. Some high-speed models use water jets instead of propellers. Engine types include gasoline and diesel internal combustion engines and electric motors.

Hull forms include displacement, planing, and semi-displacement shapes. Materials vary from fiberglass and aluminum to wood and composite laminates. Motorboats can be purpose-built for speed, stability, range, or maneuverability, and power-to-weight ratios influence performance and handling.

Common uses include leisure cruising, day fishing, water sports, competitive racing, and transport of people or goods in coastal or inland waters. They are regulated by national or regional authorities, with registrations, operator certifications, and mandatory safety equipment depending on jurisdiction.

Safety equipment typically includes life jackets, navigation lights, visual distress signals, and fire extinguishers. Operators must follow local navigation rules, weather considerations, and load limits. Licensing and operator training requirements vary widely by country and region.

Environmental considerations include fuel consumption and emissions from combustion engines, as well as noise. Electric motor options reduce emissions at the point of use and are increasingly common for small to medium vessels. Regular maintenance is required for engines, fuel systems, and hull integrity.
