Quick Summary

The term "hydroplane" can refer to two distinct types of watercraft. One definition describes a powerboat specifically designed for racing, engineered to skim across the water's surface at high speeds. This type of hydroplane is characterized by its ability to achieve rapid movement over water.123

The other meaning of "hydroplane" is a seaplane. Additionally, the term "hydrofoil" is related, describing a boat or ship that uses underwater fins to lift its hull clear of the water as it gains speed, thereby reducing drag and increasing speed. Hydrofoil ships, while faster than conventional designs, are generally limited to moderate sizes.34
