Robline Dinghy Star Pro 3mm - 1/8" (DST-3).
Standard rope used as halyard on 49er & Co. Dinghy Star Pro is the standard rope for skiff and dinghy classes. It excels due to highest abrasion resistance at minimum stretch.

* The data are typical values without warranty or guarantee.
** The value in daN (1 daN is about 1 kg) indicates the load at which the rope would break. The specified breaking loads are values determined in testing in our laboratory. In practical use, these values may deviate depending on the type of use. The breaking loads were determined for free lengths of rope and will be decreased by splices or knots. When defining a rope's dimensions, we recommend to apply a ratio of working load to breaking load of at least 1:5!
Robline's top-of-the-line dinghy rope - developed and produced without compromises
This product was developed without compromises, contains only the very best raw materials, and lives up to the latest manufacturing standards. Robline's aim was to take Robline's dinghy ropes to another level, something we have definitely accomplished in the form of Dinghy Star Pro. By using Dyneema® SK99 fibers in the core, we obtained extremely high breaking strength values in the core, combined with zero creep - simply perfect!
Its cover made out of PBO/Dyneema® SK78 makes Dinghy Star Pro extremely resistant to abrasion and UV. The grippiness of the PBO used for the cover makes this rope grippier, further improving its functionality, especially when it is used as spi halyard. Dinghy Star Pro is a must-have for every regatta racer.
Aplications: Dinghy • Spinnaker/ Gennaker Halyard (1).
• Foresail Halyard (2).
• Tack-Line (3).
Features
• Lowest stretch and highest breaking strength.
• Abrasion resistant.
• Low weight.
• Soft.
• Kink free.
• Resistance to high temperatures.
• Good ability on winches.
• Good in cleats.
• Low water absorption.
• Spliceable.
• Dyneema® core: lowest weight with the highest breaking strength.
Polyethylene which is the raw material for Dyneema® is changed on a molecular basis and in addition is stretched in one direction. These stretched molecule chains increase the breaking strength and decrease the elongation. Therefore Dyneema® has the lowest stretch at break of all synthetic fibers. Dyneema® has a very low specific weight and is therefore buoyant. The only disadvantage is that it creeps more than some other raw materials.
This means the cover can easily be removed from the rope ends without reducing the breaking strength due it's fiber shows a permanent elongation under load. Dyneema® is used as core material in high-tech ropes. The core will carry the load whereas the cover is just used for abrasion and light protection. Therefore Dyneema® it has too a good abrasion resistance and resistance against sunlight.
