What type of cloth did the Royal Navy prefer for its sails?
Short answerLightweight canvas, with different properties from modern canvas: it could tear around a shot while resisting fraying and remaining easier to repair.
NotesRoyal Navy sails used lightweight canvas, though the historical material differed from modern canvas. It could tear around a passing shot while resisting fraying, which made repairs easier. Ripstop provides a loose comparison for this behavior, without implying that the fabrics had the same construction. HMS Victory's fore topsail from Trafalgar survives in recognizable form, and other examples of historical sailcloth also remain.
