A ski boat is a type of watercraft designed for waterskiing and other water sports. The term "ski boat" can be used interchangeably with other synonyms, such as wakeboard boat or tow boat. Wakeboard boats are similar to ski boats but are designed with larger engines and ballast systems to create larger and more defined wakes for wakeboarding. Tow boats are designed to tow water skiers, wakeboarders, and other water sports enthusiasts. They are typically equipped with powerful inboard engines, specialized towing equipment, and ballast systems. Other synonyms for a ski boat may include speed boat, power boat, and motorboat.
