Routine naval supply records expose a problem historians face when practical knowledge was never written down. An eighteenth-century rope order might survive only as a government aggregate because sailors and dockyard officials already knew the standard load for each rig. Reconstructing an individual ship's needs means combining incidental measurements with assumptions about wastage, corruption, and variations between nominally similar vessels. The problem becomes sharper when a captured Spanish ship receives Royal Navy rigging adapted to different fittings and operating practice. Tacit knowledge shaped both ship design and the record historians inherit.

Rope accounts and missing practical knowledge
Aggregate rope orders, wastage, corruption, and adapted Spanish rigging show why tacit naval knowledge is difficult to reconstruct from surviving records.
