J80 - Tacking Angle


Recommended Posts

We've been having some issues with our Tacking angle north of 105 degrees total upwind.  We're sailing with a 134 Genoa most of the time in under 10 knots of breeze.  We're looking for any tips or tricks on how to improve this.  Its likely our rig tune that has out out of wack.  Thoughts, comments, heckling?

Any difference in highest AWA on either tack? 

 

On port its slightly higher.  Just trying to figure out if we just need to reset the entire tune all together.  Mast rake, etc....

some people in The Netherlands doing winterseries on the J80's have been running annalisa software to fine tune their performance. no beef in that company, just that it seems to really help with analizing potentials and possible gains. 

no beef in the company.

If you can’t pinpoint what is causing the difference from port tack to starboard then yes, you do need to reset the tune. Back to base settings for everything. Make sure the mast is straight in relation to the boat. It may be in column but it may be canted to one side or the other, skewing the angles between tacks.

Get the rig centered First.  Main Halyard and a bucket (filled with water) works and see if it is the same on both sides.

Some would say that there is nothing symmetrical on those boats so measure a spot from the stem - aft.

then, do what everybody else says here...

 

Sail safe! - Have Fun!

I would use the jib halyard rather than main.  The top is in supported and the shroud enter at the jib halyard location.
