An 18th-century frigate typically had three masts, with a total of around 15 to 20 sails, depending on its size and design. The sails included square sails on the fore and main masts, and a spanker or gaff sail on the mizzen mast. The exact number could vary based on the ship's configuration and intended use. Frigates were designed for speed and maneuverability, which influenced their sail plans.
Two-masted ships, often referred to as "schooners" or "brigs," are sailing vessels characterized by having two masts that support their sails. Schooners typically have a foremast and a mainmast with sails set on both, while brigs have square sails on both masts. These ships were popular in the 18th and 19th centuries for trade and fishing due to their maneuverability and efficiency under various wind conditions. Their design allows for a balance of speed and cargo capacity, making them versatile for different maritime tasks.

Trapezoidal, actually. But the square sails were called square sails. Lateen or square could be referred to as yards.
Triangular sails, or lateen sails, were developed to improve sailing efficiency and maneuverability. Their shape allows for better wind capture, enabling boats to sail at various angles to the wind, including into the wind itself. This design was particularly advantageous for navigating coastal waters and exploring new territories, as it offered greater control and speed compared to traditional square sails. The innovation of triangular sails played a crucial role in maritime trade and exploration during the Middle Ages and the Age of Discovery.
