A pinnace can be described as a swift, short-distance starship that was transported by a bigger ship. Generally, pinnaces were a bit bigger than starfighters, and they included some space for cargo; therefore, they saw use in both combat and logistical support. A specific example of a pinnace is the Ulig Abaha Ltd. #2 Warpod.
In our own reality, a pinnace was a diminutive vessel, moved by either sails or paddles, and frequently employed for reconnaissance and minor incursions.
