Drop Head Title Explanation Descriptive New (1 results)

4pp. Single sheet, printed on both sides, folded as issued. With an engraved nautical diagram and an engraved vignette. Creased, three horizontal mis-folds, very short central tear to head, some spotting, 'New Rig' in manuscript to gutter of first page. A rare ephemeral survival of a description of a newly invented early-Victorian system of mast and rigging positioning, the primary advantage of which being that it allows one to tack and beat a vessel to windward sternways 'the possibility of so doing being entirely obtained from the power and action of the "inverted swivel- yards," and the fore-and-aft triangular sails'. OCLC records copies at two locations (BL and Mariners Museum), both of which bound with Dempster's The problem: its origins and development, with a brief sketch of the life of the inventor, during a thirteen years' residence in India and China (Glasgow, 1843). COPAC adds no further. Size: Quarto.
