laser vago sail trim problem

My first post so quick hello to everybody.

In 8-15 knts wind,having problems with jib trim whilst beating or close reachig on my Vago.

Upper windward t/tail dancing, lower leeward t/tail dancing, mid t/tails fine or matching upper.

Main  - no cunningham, & combinations of no/little vang and/or very tight/eased sheet.

Have shroud tension at 13 (set by jib halyard),Laser say max must be 15.

Any clues?

Indeed!

Seems very slack to me too, but thought if Laser are saying absolute max 15, thought 13 in this windspeed would suffice.

Sounds like you have too much twist in your jib ie the bottom of the sail is over-sheeted in order to sheet in the top of the jib far enough.

Well I can never get ALL the teltails looking the same on my laser 2 either.  The top pair are usually astray in a strong wind.

I'd guess you need more jib leech tension to create less twist which means pulling down on the jib tack more.  However, I also guess the Vago has the same lack of forward / aft adjustment on the jib cleat position as my laser 2; so you can't adjust the jib leech tension independently of its angle of attack; that means you can't control the amount of twist in the jib very well. Can you attach the jib sheet higher up the sail?  Ie is there more than one attachment point? Or if poss. move the cleats towards the bow?

Failing perfect adjustment just concentrate on getting the average of the bottom pair of tell tails right, as the bottom of the jib is where most of the power is. 

Doubtless someone else will have a different opinion.. (always do on this site) so you'll have to take an average!

Good luck.

PS: beware of too much tension.  RS400s are stiff fibre glass, the VAgo isn't!!!

As Nick A says, it sounds as if there's too much twist in the jib. Can you not just sheet it harder?

If you're already stretching the jib to death, try raking the mast further forward. If that would mean raking too far forward for helm balance, try adding a shackle between the jib and furler to raise the whole jib and effectively steepen the sheeting angle.

When the boat still gets beaten by everything in sight, sell it and buy a 3000!
