A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture.Although sailboat terminology has varied across history, many terms have specific meanings in the context of modern yachting. A great number of sailboat-types may be distinguished by size, hull configuration, keel type, purpose, number and configuration of masts, and sail plan.A sailing ship boat is a type of watercraft that moves primarily by using sails and the power of the wind rather than an engine. These vessels are designed with masts, rigging, and large fabric sails that capture wind energy to propel the ship forward across seas, rivers, or lakes. Sailing ships have been used for centuries for exploration, transportation, trade, and even warfare, making them an important part of maritime history.

Traditionally, sailing ships were built from wood and carefully crafted to withstand long ocean journeys. Different types of sailing ships exist, such as sloops, schooners, brigs, and full-rigged ships, each with unique sail arrangements and sizes depending on their purpose. Navigation in a sailing ship requires skill, as sailors must understand wind direction, currents, and weather conditions to control speed and direction effectively.

Today, sailing ship boats are commonly used for recreation, sport, tourism, and historical preservation rather than commercial transport. Many people enjoy sailing as a hobby because it offers a peaceful connection with nature and the sea. In addition, restored traditional sailing ships are often displayed in museums or used for educational voyages to teach maritime heritage and traditional seafaring skills.
