![]() The removal of this mid-layer results in a reduction in the finished rope diameter over the last 2 metres of the line. Therefore, when splicing LIROS Dynamic Plus and LIROS Racer, the sacrificial mid layer is cut away approximately 2.5 metres from the end in order to make room for the double-thickness Dyneema. To complete a successful core-dependent splice, the outer cover needs to accommodate a double thickness of the Dyneema core. These both come at the expense of outright performance but represent a significant upgrade from 100% polyester. The Marlow Cruising Performance version involves blending an SK75 Dyneema with Polypropylene to make it less expensive. LIROS have designed a cost-effective Cruising Performance solution by reducing the amount of Dyneema SK78 in the core compared with High-Performance Racer Dyneema SK75 and SK78 are commonly used in 'Cruising' - SK78 in 'Racing' and 'Extreme' - SK99 in Extreme.Cruising Dyneema offers a performance edge over 100% polyester without incurring the full cost of Racing Specification Dyneema.The higher the number, the higher the specification and the more it costs. ![]() Dyneema is denoted and rated by an SK number: SK76, 78, 99.Dyneema is significantly more expensive than polyester.These split naturally into three different groups:Ĭruising Performance ~ Racing Performance ~ Extreme Performance Dyneema (High Modulus Polyethylene) Facts and Features: Jimmy Green Marine offers a range of running rigging lines with a combination construction: Polyester cover combined with a Dyneema core. ![]()
