Scale: 1:48. Plan showing the proposed schooner sail plan for the Quest (1917), a Norwegian sealer, prior to being converted to an exploration ship for the Shackleton-Rowett expedition to the Antarctic in 1921. The conversion was undertaken at the Woolston Yard of John I Thornycroft. Frank Wild's published account recalled that the rig need to be altered for the Antarctic expedition: "Two yards were fitted, a topsail yard, 39 feet in length, and a foreyard to carry a large squaresail, 44 feet in length. The mizen-mast was lengthened to give a greater clearance to the wireless aerials." The plan shows these yards fitted.

The vessel was classed as a steam yacht under the Royal Yacht Squadron flag (Frank Wild's account states "Sir Ernest received what he considered the greatest honour of his life. The Quest as his yacht was elected to the Royal Yacht Squadron. Perhaps a more ugly, businesslike little “yacht” never flew the burgee, and her appearance must have contrasted strangely with the beautiful and shapely lines of her more aristocratic sisters.")
