S CUP

High-performance regatta rope with superfibre core at top price-quality ratio

S Cup is a high quality rope with a well balanced construction for racing and ambitious cruising on sailing boats. This racing rope has a double braid construction with HMPE-superfibres Stirotex in the core, covered by a HT-Polyester braid. S Cup is available with many colours in a modern mottled or solid design and offers many splicing options to make a perfectly matching line for your boat from this rope.
You can order S Cup from ø3mm to ø16mm in many colours directly here. At Premiumropes we have large stock and can quickly splice it to your configuration and ship quickly to you or directly into the marina.

Our S Cup is popular in sailboat racing and for cruisers both on small trips and long voyages.

This top level racing rope has been designed by Premiumropes for demanding sailors, which are looking for lines that take up the challenges on board. Whether club-regatta, weekend-trip, blue-water-cruising or offshore-racing - S Cup is the matching rope for your sailing activities for many seasons.

S Cup uses superfibres in its core for minimal elongation and is used as halyard for your mainsail, genoa or other sails. It will keep the halyard tension over time and your sails will be performing better with an optimum leech tension.

Additionally the weight in the rig can be reduced due to use of HMPE-superfibres in the rope with the following options

• Tapering S Cup - stripping the cover on the first part of the rope makes it much lighter without any performance or strength issues. The core is UV-resistant.
• Weight advantage of superfibre - the density of Stirotex fibres (HMPE) is less then that of Polyester making it a less heavy rope
• Stronger than steel - S Cup uses the HMPE Superfibre Stirotex in its core, which is many times stronger than yachting ropes from Polyester. It is possible to use a smaller rope diameter and still keep the requirements for the breakload. That way S Cup reduces the weight in your rig.

What is Stirotex?

Stirotex is the name of the superfibres, out of which the core of S-Cup is braided. This superfibres are made of HMPE, high-modulus-poly-ethylen, which have superb technical properties. Stirotex, like Dyneema, is a brand name for HMPE fibres.
With Stirotex having the same strength, weight and UV-resistance as other HMPE fibres, the Stirotex core in S-CUP is a very price attractive alternativ.

How to make an eye-splice into S-Cup ropes?

The steps to make a proper eye-splice into ropes with superfibre core is explained in this video. As the Stirotex core is UV resistant, it is most easy to splice the core and leave out the cover.
