Our Viper 640 Spinnaker Sheets all come in a 5/16 in diameter for easy handling in a variety of line options depending upon your performance, cost and personal preferences. All options are designed to be continuous with both ends tied off to the clew of the spinnaker; you could also luggage tag the sheet to the spinnaker if you'd prefer to have two ends instead of a continuous sheet.
The line used for this spin sheet configuration is a high performance, Marlow Excel Fusion line. This line is soft to the touch, but firm enough in construction to hold well in cleats. The cover texture makes it easy to hold on to under load. Both the core and cover materials offer zero water absorption so it always stays light. With its small diameter, 100% Dyneema SK75 core, stripping the jacket aggressively reduces line diameter and weight. Unlike other lines with 100% polypropylene covers, Excel Fusion has a blend of Dyneema and polypropylene to better deal with abrasion and heat (melting) under high loads.
