The Patented Hoyt Offset
Rig
The fundamental difference of this patented rig is that both the boom and the horizontal gaff are carried
out to the side of the mast by a special offset arm. This provides a totally clean leading edge to the mainsail,
free of the windage interference of the mast, which penalizes the performance of conventional mainsails.
This offset
arm also allows the forward projection of both boom and gaff ahead of the mast, creating a balanced rig that enables easier
trimming in the same way that a balanced rudder enables easier steering. The Offset Rig also delivers an important
new safety feature by significantly softening the force of the jibe. The approximate 20% of the sail area that is carried
ahead of the mast acts as a brake by slowing the swing of the sail across the boat during the jibe.
A tensioned
stay connects the forward end of the horizontal gaff to the forward end of the horizontal boom, and serves to guide sail hanks
on the luff during hoisting, lowering and reefing. A similar tensioned stay connects the aft end of the gaff with the
aft end of the boom, which assures that they will both act in concert, avoiding the wasteful twist off that has traditionally
afflicted gaff rigs.
By enclosing the large diameter free standing mast with a light, stiff, aerodynamic sleeve
that freely rotates 360º like a wind vane, windage drag is reduced by 75%. The combination of eliminating the windage
of the traditional maze of spreaders and stays and eliminating the harmful effect of the mast at the leading edge of the sail
creates a rig of unmatched aerodynamic efficiency. Read why this is important by clicking here.
In Summary
The Patented Hoyt Offset Rig uniquely delivers:
- More drive due to a totally clean leading edge and the optimum square
headed profile that minimizes tip vortex and induced drag
- Reduced sheeting
loads due to the balance effect of carrying 20% of the sail area ahead of the mast pivot point
- Greater safety by dramatically softening the "slam" factor of the jibe - the most dangerous maneuver
in sailing
- A drastic reduction in windage drag by eliminating traditional
rigging
- More economy by simplifying the rig to 3 light, strong, carbon tubes
- Balanced reefing that lowers the center of effort of the sail without alternating the balance
and maintaining a clean leading edge
