Scheda tecnica e prezzi

Base Settings:
Are the starting point for all rig settings and are used between 12 - 16kts. It is always a good idea to adjust all rig settings back to base at the end of a days sailing otherwise it is easy to forget or lose the reference point.

Forestay Length:
forestay length should be standard as supplied by the factory without any additional toggles added. This forestay length is set for all wind conditions but obviously rake will increase as the shrouds are tightened.

Jib Cars:
As supplied by the manufacturer with holes numbered from 1 going Backwards.

Cap shrouds, D1s and D2s:
Base settings measured with Loos PT2M rig tension guage. Light and Heavy settings achieved by adjusting bottlescrews on or off from the BASE settings.

Tips:
With the swept back spreader rig it is important not to over tension the cap shrouds or the mast will compress and fall off at the top.

Hints:
The aim with D1s and D2s: adjust until the mast is straight sideways when sailing upwind. Mark all the bottlescrews so that it is clear the correct way to turn if you want to tighten or loosen the rig!

General comments:
I never used much vang upwind in any breeze - just enough to take up slack.  Got onto backstay quite early.  Tended to keep boom up track near middle in most conditions.  Used cunningham harder and earlier than old mainsail design.  Jib halyard tension and sheeting position quite critical.  Didn't move the jib cars much as clew is close to track.  In less than 6 kts I eased another 2 turns of everything from the 6-12kt setting.  Keeping the caps on base in 6-12kts definately worked well and loosening D2s more than D1s worked too.
