In an attemp, to work on Siskin's luffbiting tendencies, I am changing Siskin's rig to an AeroJunk - based on the ideas of Paul McKay and on Pete Hill's interpretation of this idea.

These are more or less the specs of the first wishbone:

• Aluminum 40 x 20 x 2 mm
• Rods of 4 meter
• Spreaders SS M-10 threaded rods
• Spreader front - 430 mm
• Spreaders 2 + 3 - 740 mm - 15 cm apart - mast 13 diameter
• Spreader rear - 200 mm
• Sailplan behind mast: 4 times 2,95 m x 1 m + 1 top panel
• Sailplan in front of mast: 5 times 0,85 m x 1 m resulting in 24% of sail area in front of mast
• Front and rear spreaders tendency to warp.
  

Suggestions?
Please let me know.

Best regards,

Antoine
