On my Oceania 45, I made a couple small tweaks that were very helpful. Both additions involved adjusting the job lead. First I added in-haulers. It is simply a snap shackle on a line that pulls the jib clew inboard. The result is about 3 degrees better pointing
The second addition was an outboard lead attached with dynema line at the chain plate. This moved the clew out for better performance off the wind.
For next season, I'll add Code Zero to my sail inventory. That should improve performance for points of sail between the jib and the asymmetric chute.
