Isonic 127 2011 vs 2012 and weedfin?

[Martin.M.A]

Lessacher .... Is he alive?

It seems totally impossible to get any feedback or interest from this lessacher!
Have e-mailed several times.
Someone said / wrote that you should put money into their account and then their "conscience" did they send the fin ........... feel sick, I think.
Anyone have a good connection so I can get some help ordering a fin?

considering a lessacher duo weed formula 40 for my 9.5 sail to my Isonic 127 2012 .... or what do you think?

What email address did you use to contact Wolfgang Lessacher?
He is a member here on this forum.

The Lessacher Formula 40 cm Duo will work great for your 9.5 m2 sail.
The 36 cm Duo could work as well.

Hello! Roger !
I do not address here but will look at it tomorrow on my work computer.

I thought as I said buy a new grass fin to my new Isonic 127 2012 Carbon. I weigh about 88 pounds.
What's the big difference in the Weed and Duo Duo Formula Weed?
Is there a difference in the slope in degrees on these?
Should not it be 45 degrees for the grass to drop soon?
Do remember sailing with my camber 9.5 sail and it's pretty much grass where I sail.
Bought first one Chamäleon 36 but maybe it was a little small when the fin is supposed to light wind sailing.,
What do you think ...... Duo Duo Formula Weed and Weed?
Sincerely, Martin Sweden

Hi Matin,
The Formula Duo Weed is all you need. The "Formula Duo" is 40 cm (the largest Wolfgang makes).
The 36 cm Duo Weed would probalby work with your 9.5 if you are sailing powered up.
The "duo" simply means the fin is Wolfgang's asymmetrical design.
Convex at the top on one side....concave at the same level on the other side.
Convex at the tip on the opposite side from the top/base of the fin and concave
on the opposite side in the same area.
Wolfgang has worked out (many experiments and prototypes I'm sure) what percentage of the
fin needs to be convex to give the board good balance and spin out resistance.
No one else does anything even close to Wolfgang's asymmetricals.
Some of his speed asymmetricals are amoung the fastest on GPS Speedsurfing.
The rake angle of Wolfgang's fins can be a bit steeper as the weeds go off around the
foil of the fin, rather than sliding down like all other weed fin designs.

Have you tried a Lessacher duo? I've tried some of your other suggested weed fins,
and several more that are not on your list.
Given a choice, I'll sail the Lessacher Duo as it seems to out perform all the others overall.
