Which type of vessel is usually fitted with both sails and an engine for propulsion?

The correct choice describes a vessel that is typically equipped with both sails and an engine for propulsion, which is characteristic of a yacht. Yachts are designed for recreational purposes and can function well with either propulsion method, allowing for flexibility depending on the conditions. When the wind conditions are favorable, sailors can utilize the sails for a more traditional sailing experience. Conversely, when conditions do not permit sailing, the engine can be used for navigation, making it a versatile choice for leisure activities on the water.

In the context of the other options, while cruisers can be a subset of yachts designed for long-distance travel, they may not always have sails and engines. Freighters primarily rely on engine power for commercial transport of goods and typically don’t utilize sails. Fishing boats may also be powered mainly by engines, though some can feature sails; however, they are not commonly designed to function optimally with both propulsion types like a yacht or cruiser would. This understanding clarifies why yachts are the most representative example of a vessel designed to incorporate both sails and engine power seamlessly.
