Hemp and Manila (Hemp)

Hemp is famous for being part of the marijuana family, but has many uses.  Products from hemp include seeds, oil and fiber from which food, cloth, paper and building materials can be made.  A major use for hemp in the 16th to mid-19th century was in the making of rope, especially for use on sailing ships, and sail canvas.

However, hemp rope needed to be tarred in order to protect its integrity from heat, rain and salty ocean water.  So in stepped manila hemp (called such but it isn't actually hemp) made from the fibers of the Abaca plant (in the banana family) and is the strongest of the natural fibers.  It is stronger, more durable, and more flexible than hemp.

I recently made a trip to Mystic, Connecticut to visit with my friends Rick and Lynne who drove up from New Jersey and we visited Mystic Seaport which exhibits a portion of the original buildings of the Plymouth Cordage Company's ropewalk built in 1824.  The original building was over 1,000 feet long (needed to make a 600 foot rope).  Natural fibers are first spun into yarn, many yarns are spun together to make a strand. then three strands are twisted in the opposite direction to form rope.

A lot of rope is needed for sailing ships - such as the Joseph Conrad, a square rigged ship, built in 1882 in Copenhagen.





The Joseph Conrad is also on exhibit in Mystic Seaport.  More about my trip to Mystic in the next post.

  1. C, great post! I too was fascinated at the production of rope which I had never really given much thought about. Now that I've seen what it took to make it I have a whole new respect!
