Running stay or back stay
This document discusses the advantages of using Dyneema stays over traditional wire stays for sailing applications. Dyneema, also known as D-Pro or Dynex, offers significant weight reduction while maintaining strength.
Specifications
Dyneema stays weigh up to 10 times less than wire stays but provide equivalent strength. The document lists various dimensions and their corresponding breakloads and weights:
- Dimension 4: Breakload 1250 kgs, Weight 7 grams per meter
- Dimension 5: Breakload 2600 kgs, Weight 13 grams per meter
- Dimension 6: Breakload 4300 kgs, Weight 23 grams per meter
- Dimension 8: Breakload 5600 kgs, Weight 47 grams per meter
- Dimension 10: Breakload 7000 kgs, Weight 75 grams per meter
Measuring and Installation
The document provides guidance on measuring stays based on the type of terminals used. It includes illustrations for clarity. Standard stays are delivered with eyes at both ends, without T-terminals.
Considerations for Class-Boats
Sailors using class-boats should be aware of potential class-rules that may affect the use of Dyneema stays.
