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 Charleston-Spar range fulfils the requirements of these different design geometries and is known for its reliability and performance.  The Charleston-Spar multihull range is chosen by the best multihull builders in the world.

 CHARLESTON-SPAR ENGINEERING

• Mast Sections:  Charleston-Spar provides the appropriate mast sections and optimises the whole mast for each particular catamarans geometry; wing masts, fixed mast or with tripods.

•  Custom: Our design and production process allows us to optimise the configuration of your mast. We build custom components specifically for your needs, as we have done for a number of projects including special spars parts, davits, toggles, cramps integrated into the mast and many others.

• Charleston-Spar has developed innovative ergonomic beam structures; refer to “catamaran beams”.
