 Identification of some pinnaces in contemporary historical documents is often difficult because there was no standardization of pinnace design, be the type "small" or "large".The term seems to have been applied to variants of what may be called the full-rigged pinnace, rather than the alternative use of the term for a larger vessel's boat.Furthermore, several ship type and rig terms were used in the 17th century, but with very different definitions from those applied today.
