Plans of a Lugger with sliding keels built by Mr. Wm. Wood of Rotherhithe, 17 June, 1789

Original draft of three figures drawn in red and black ink. Includes body, profile, and half-breadth views. Manuscript text at top left notes the builder and place date built.

This is one of four plans that appear to be associated with an early developer of a Western sliding keel, naval architect and British Admiral, John Schanck (1740-1823). Lieutenant Schanck was stationed in Boston before the Revolution and his first experiment with sliding keels appears to be represented in this plan. The date of this and the other related sliding keel plans in Clark Collection is not clear.
