Running rigging is an essential component of a sailboat’s rigging systems, consisting of lines or ropes used to adjust the sails, control the boat’s direction and speed, and secure the boat to the dock or anchor. In this post, we will discuss the different types of running rigging, with a particular focus on the differences between SK78 Dyneema core and SK99 Dyneema core.
Running rigging is typically made of a variety of materials, including synthetic fibers like polyester and nylon, and high-performance fibers like Dyneema and Vectran. The choice of material for running rigging depends on several factors, including the type of boat, the sailing conditions, and the sailor’s preferences.
Dyneema is a high-performance fiber that has become increasingly popular in running rigging due to its strength, low stretch, and resistance to abrasion and UV damage. Dyneema running rigging is typically made of a Dyneema core, which provides strength and low stretch, and a polyester or technora cover, which provides abrasion resistance and handling.
SK78 VS SK99 Dyneema Running Rigging
SK78 Dyneema core is a type of Dyneema that is commonly used in running rigging. SK78 Dyneema has a high strength-to-weight ratio and is highly resistant to stretch and abrasion. SK78 Dyneema is a popular choice for racing sailboats, where low stretch and high strength are essential for maintaining sail shape and improving performance.
SK99 Dyneema core is a newer type of Dyneema that is even stronger than SK78 Dyneema. SK99 Dyneema has a higher strength-to-weight ratio and is even more resistant to stretch and abrasion. SK99 Dyneema is a popular choice for high-performance racing sailboats, where the demands on the rigging are even greater than in other sailing contexts.
The main difference between SK78 Dyneema core and SK99 Dyneema core is their strength and weight. SK99 Dyneema is stronger and lighter than SK78 Dyneema, which can improve a sailboat’s performance by reducing weight aloft and increasing sail efficiency. However, SK99 Dyneema is also more expensive than SK78 Dyneema, which can be a factor for sailors on a budget.
