The Route du Rhum (French for "rum route") is a transatlantic sailing regatta, which started in 1978 and which is held every 4 years in October / November. The journey leads 3,540 nautical miles (approximately 6,500 kilometres) from the Grouin headland in the north of Cancale off the French Saint-Malo to Pointe-à-Pitre on the French Caribbean island of Guadeloupe. Crossing the ocean usually takes about 16 days. Depending on the weather conditions, it could be as low as 13 days.
Crossing the Atlantic in only 2 weeks would not be possible without polyamide 6. The spinnaker sails used in the boat are made of Nylon fabric, known for its light weight and high stiffness. Additionally, Polyamide 6 ropes stand out for their high strength and strong resistance to abrasion. Functional apparel textiles could not exist without the strength of nylon.
