Specifications of multihull rigging:
Multihulls are usually fitted with self-supported rigging which hold the mast with one forestay and two upper shrouds linked to the hulls with toggles. These self-supported masts consist of two groups:
1) Rotating masts, also called “teardrop masts”, or “wing-mast sections” (as on Formula 28 and 40) and 2) fixed masts. The latter are supported in various ways:
- Masts with tripods: the spreaders are linked on the front by a forward jumper which holds the mast laterally and longitudinally.
- Mid-range geometry: the mast is only supported laterally by the spreaders and large diameter shrouds (not self-supported, thus without forward jumper).
- Masts with additional rigging: without jumper on the front, or spreaders, but with lower shrouds and occasionally an inner stay.
The Sparcraft range fulfils the requirements of these different design geometries and is known for its reliability and performance. The Sparcraft multihull range is chosen by the best multihull builders in the world.
