Technical specifications & rigging
Severne's Mach 9 rigging recommendations. Luff and boom measurements are in centimetres; the boom figure is the required sail setting. Choose a boom whose adjustment range covers that length.
| Size (m²) | Luff (cm) | Boom (cm) | Recommended mast |
|---|---|---|---|
| 5.0 | 402 | 162 | Red RDM 370 |
| 8.5 | 518 | 222 | Apex Team SDM 490 |
Where shown, luff values such as 370+4 follow Severne's mast-plus-extension notation. Check the markings on your sail and fine-tune for conditions. Mast and boom recommendations are guidance; equipment is sold separately.
