Was Hemp Used In Ship Sails?

The evolution of sailmaking, a cornerstone of maritime exploration and trade, has been deeply intertwined with the utilization of hemp fibers. Hemp’s resilience and adaptability made it the preferred material for crafting sails, revolutionizing sea travel and forming strong nations in the pre-industrial age. Hemp was strategically important during the Revolutionary War, but now fiber sails are still a thing for some heritage old gaffers.

Hemp was used for making ships watertight, using it for sails, rigging, and other ropes. Hemp was also treated with tar to fill the seams between the planks of a wooden hull to make ships watertight. Hemp was commonly used to make sail canvas, which is derived from the word cannabis. Christopher Columbus’ ships each carried over 80 tons of hemp rigging and sails.

The 2018 Farm Bill gave states the authority to produce hemp but left regulation and licensing to state agriculture departments. Now, with Idaho State Department of Agriculture offering licensing and certification in 2022, hemp has helped facilitate global trade and the expansion of empires by rigging entire naval fleets with hemp sails and ropes. Hemp is 3 times stronger than jute and was preferred because it was unaffected by salt water.

Hemp fiber was also mixed with other materials, such as fiber hemp, which was used historically to form a canvas for ship sails and to make the first pair of Levi Strauss jeans. Hemp sail cloth lasted years on the open ocean, and the 252 day journey to Australia by the first fleet was accomplished with hemp sail cloth, more commonly known as linen. In some cases, hemp was used to make ropes, but hemp was more commonly used to make sails.

Are hemp seeds safe to consume?

In the last few decades, people have gotten interested in the nutritional value of hemp seeds. They can be eaten raw or used to make milk, oil, cheese substitutes, or protein powder. The FDA lists them as a “generally recognized as safe” (GRAS) food.

Hemp seeds are the seeds of the hemp (Cannabis sativa) plant. Technically, the industrial hemp plant is the same as the cannabis (marijuana) plant. But despite being the same genus and species, hemp doesn’t have the same narcotic effects as cannabis, but it still shares a similar history.

Hemp was traditionally grown to make cloth and rope, with the seeds used mainly for animal feed. The seeds were also used to treat and prevent certain health issues. Hemp cultivation declined with the rise of synthetic textiles and the use of some types of cannabis as drugs.

In 1937, the Marijuana Tax Act made hemp production illegal throughout the United States. In the 1970s, it was classified along with cannabis as a Schedule 1 federally controlled substance. It wasn’t until the passage of the 2018 Farm Bill that industrial hemp became legal again. It’s a versatile plant that many people use to make fabrics, plastic and paper bag alternatives, pet bedding, biofuel, and food.

What were old ship sails made of?

Sailcloth was woven from flax fibre during the period when England, France, and Spain were striving for supremacy of the seas. Fibre flax is still used for sails, although cotton has replaced it for better quality canvas. Cotton sails became popular in Europe after the U.S. racing yacht America, using cotton sails, decisively defeated a fleet of British yachts in 1851. Cotton sailcloth has the advantage over flax, hemp, ramie, jute, and combinations of these materials as a fabric in that it can be woven more closely and therefore will not stretch out of shape as easily or lose as much wind through the pores of the material. Sails made of cotton, however, are very stiff, which makes them difficult to handle.

The chief modern users of quality sailcloth are yachtsmen, who generally prefer the polyester fibre Dacron (or Terylene, its British equivalent). These synthetic fabrics were first introduced in 1950, and they proved much superior to any type of cotton or other synthetic materials. Sails made of Dacron maintain just the correct amount of stretch and so require no “breaking in” period. The greater strength of the fabric permits the use of lighter-weight sails, which maintain their original shape for years. Because this fabric is heat-treated by pressing it between hot rollers of metal, its fibres are flattened and interlocked, giving it a smooth, almost frictionless surface and very little porosity. The stitches, however, do not mesh with the fabric but protrude above the surface of the sail, causing the sail twine to become abraded more rapidly than with other sailcloth.

The basic steps in manufacturing a sail may be outlined as follows: The sailmaker studies the sail plan or measures the vessel’s rig. The stretch and the amount of draft (i.e., the curvature of the surface) are calculated. The actual plan of the sail is chalked out to full scale on the floor of the sail loft. The cloths are laid down over this plan, and their actual length and shape are marked on each individual cloth. The cloths are numbered and then cut to the dimensions outlined by the markings. The cloths are sewn together. A special sail twine is used as thread, and after the needle is threaded the twine is waxed so it will hold the right-hand twist then given to it. This twist helps the thread to mesh with the fabric. After all the cloths are sewn together, patches are attached to the corners, and tabling (hems on the edges) is sewn on the luff (forward edge) and the foot—the places where the greatest strain develops. The finishing touches are applied. The luff rope is sewn inside the leading edge of the sail to prevent the sail from being stretched out of shape. Strong ropes (boltropes) are sewn to the luff and foot, and various fittings, such as metal slides, grommets, reef points, cringles, etc., are attached to the sail.

What equipment on a ship was made from hemp?

Hemp was used for a ship’s sails, rigging and other ropes. Hemp was also treated with tar and used to fill the seams between the planks of a wooden hull in order to make ships watertight. This process is called caulking. Sailors’ clothes were often made of hemp, and captains kept the ship’s log on hemp paper.

How did wooden ships not rot?

Wooden boats were made water-resistant by putting tar in the boat’s hull. The pitch or tar sealed the wooden boards of the ship together, keeping water out and allowing the boat to float. Sailors also utilized oil on their sails in another form of waterproofing.

Why is hemp fabric not popular?

Not Rich In Color. A disadvantage of hemp clothing is that, since it is natural, it doesn’t have the color richness that synthetic materials do. You could argue that hemp fabric never looks as ‘nice’ as synthetic clothing, instead having an organic, natural look. So, hemp might not be for you if you love vibrant colors. However, by providing subtle and neutral colors, one could argue that hemp fabric is excellent for accessorizing and can provide a highly sophisticated look.

There Is A Stigma Surrounding It. Even as hemp continues to crop up in the market, many individuals are still skeptical about it. Indeed, hemp is related to marijuana, and this only adds to hemp’s drawbacks because some have a challenging time understanding the difference between these two products.

Hemp is also strongly associated with hippie culture – which is certainly not for everyone. Some individuals want to avoid falling into this category, although this is all down to personal preference.

What were Viking ship sails made of?

How did the Vikings ships move?. The ships were powered by oars or by the wind, and had one large, square sail, most probably made from wool. Leather strips criss-crossed the wool to keep its shape when it was wet. Viking ships also had oars. A steering oar or ‘steerboard’ was used to steer the ships. It was fastened to the right-hand side of the ship at the stern (back).

What was life like at sea for Vikings?. There was no shelter on these vessels. At night, Vikings might pull them up on land. They’d take the sail down and lay it across the ship to make a tent to sleep under. Or, they’d pitch woollen tents onshore. If the crew was far out to sea they’d sleep on deck under blankets made from animal skin.

Food would have been dried or salted meat or fish. It could only be cooked if the crew were able to land. They’d drink water, beer or sour milk.

What were Greek sails made of?

Flax was the main material for sails in Greece, according to the written sources (Nosch 2014; Spantidaki 2018). The use of hemp, especially for ropes, is also noted from the 5th century BCE.
