Fabric strengths
Tensile strength and resistance
Fabric must be storm-resistant.
The technique expresses this in tensile strength and tear resistance.
The parameters are given in kilograms below.
| Fabric type | Tensile strength kg | Elasticity % | Tear resistance in kg |
| Titan spun | Warp 116 | 18 | 10 |
| Titan spun | Weft 122 | 23 | 10 |
| Supralon | Warp 39 | 29 | 2 |
| Supralon | Weft 58 | 56 | 1.9 |
