Cressi's floating elastic rope is made of 100% floating latex and a solid 4 mm diameter structure for greater resistance. It includes two plastic carabiners and has a coefficient of elongation up to x7, coefficient of use of x4. This rope allows the perfect perpendicular positioning of the buoy, improves hydrodynamics and its tension creates a spring effect at maximum elongation that recovers between 1 and 1.5 kg of ballast.
