This is a lot of three blueprints for the same ship. Blueprints are stamped with: "Henry J. Gielow, Inc. / Naval Architects Engineers and Yacht Brokers / 25 West 43rd Street, New York City"

This ship may have been named "Windward" for John M. Groetchins / Goetchius / Goetchins

Plan 1: "No. 266 / Plan of Auxiliary Yawl / for John M. Goetchius, Esq. / MIDSHIP SECTION / October 15, 1906 / Gielow / Engineer and Naval Architect / 52 Broadway, New York City" / 22"x29"

Plan 2: "No. 266 / Plan of Auxiliary Yawl / for John M. Goetchius, Esq. / Length over all ... 93 ft 3 ins. / Length on load water line ... 64,, 2,, / Beam, extreme ... 19,, 6,, / Draught ... 10,, 6,, / October 15, 1906 / Gielow / Engineer and Naval Architect / 52 Broadway, New York City" / 20"x54" [4" strip of tape along back of blueprint]

Plan 3: "No. 266 / Plan of Auxiliary Yawl / for John M. Goetchius, Esq. / June 18, 1909 / Gielow / Engineer and Naval Architect / 52 Broadway, New York City" / 27"x42" [ink blots on the back of plan, with blue writing "plans of yacht"]

All plans are folded with light water stains (which don't affect the essence of the plans). Some loss around the corners of the folds, as shows in photos. 

Thank you!
