Hemp for Victory and the Spanish Armada: When Governments Encouraged Hemp Cultivation
Although cannabis became a controversial subject throughout the 20th century, hemp played an important role in the economy and industry for several centuries. For this reason, the status of the Cannabis sativa plant was very different: its cultivation was encouraged and rewarded. Let's take a look back at centuries of hemp history. Why was hemp worth its weight in gold to a ship? Before steel and synthetic fibres, a warship was basically wood, sails and miles of rope. And those sails and ropes (the famous rigging) came mainly from hemp fibre. Yes, the very same species you lovingly tend today in your grow tent. The figures are mind-boggling. According to a study published in the Revista de Historia Naval, just over 20% of the cost of an 18th-century Spanish ship of the line came from hemp materials, and a three-decker required around 150 tonnes of fibre. Textile hemp revolutionised the maritime industry. Just imagine how many plants went into every ship! Why hemp in particular? Because its fibre withstands tension, wear, moisture and sunlight better than flax or esparto grass. For a sailor, that meant something very simple: the rigging wouldn't snap in the middle of a storm. It's no coincidence that hemp was as essential to sailors as it was to hangmen, a grim comparison which, as we'll see, appears in Hemp for Victory itself.
