i have been reading some material on boomvang adjustments and i am confused. I know each boat is different and trimming maybe different but i am looking for either specific adjustments for the boats i sail or general rules for adjusting this convoluted piece of awesome.

Growing up in sailing camps i sailed albacores (current boat i am sailing), 420's, Pirates (in sea cadets), lasers. I learned that when sailing upwind you tighten your boomvang and when going downwind you loosen it completely. Thats basically all they taught us.

Now from sailing around the old dogs and reading about the boomvang, i hear that going downwind its better to tighten the vang rather than loosen it. I also hear that the vang can be loosened upwind as well.

so i don't know what to do with the vang now. I am hoping you guys can help me out with minimal scathing noob remarks

I am looking for answers concerning when to tighten and when to loosen the vang based on wind conditions and points of sail. if you can please explain when twist is optimal for the sail and when it isn;t. finally, if you can explain angles of attack i would greatly appreciate it.

preping for next seasons races,
