I would like to ask two questions.

1. Could You please more exactly describe the differens between the "eggshell" Isonic 127 2011 and Isonic 127 2012. A potential buyer i Sweden hesitates and I understand him.

2. What kind of weedfin do You think would suite Isonic 127? Is Lessecher Chamelon 36 ok or is it to small? Other choice?

Thanks

Pelegrin

i donīt think there is any difference in construction between isonic 2011 and 2012.
Itīs not an "eggshell" its carbon fibre fabric, epoxi, polyurethane (sandwich) glass fibre, and Extruded polystyrhene.

2. I ride a isonic 127 carbon with a chameleon 36 and itīs way to small in lightwind but works without spinout with a 9.3 sail, itīs a lot better when powered on a 7.6, but then the board starts to feel too large.
Check out lessacher duo weed formula, i think it will work better for light wind.

Hi Pelegrin,
As Kapten suggests the Lessacher Duo formula (40 cm) will work well for sails => 9.0 m2 .
If you use smaller rigs, the Duo Weed 36 will be fine up to 8.5-9.0.
They shed weeds extremely well and are almost impossible to spin out. Go upwind pretty well for a
weed fin as well.

TankYou for Your answers! The potential buyer has ordered one carbon 2012 and I will not put up the "eggshell-discussion in this thread.

I wonder if You could help me with anouther - If I want to be real fast using Isonic 127 with 7.5 - what fin would You recommend, if I not sail att open sea?

I allready have two Select S10, 51 and 46 cm. Will they do?

Read somewhere else on this forum that 2011 was 80gr/m2 carbon+60glass on deck and 2012 was 150gr carbon...there are so many other factors than just the weave

Those finns will do more than fine! I found my 127 really sensetive on trim regarding mastfoot position, more so than most boards
when powered on. A 7.6 1-2 cm made a big difference. Move it back and this board will really fly of the fin

I would defenitly try the 46 with a 7.5 first anyway, if you are powered up.

Will go out in the garage and check where i have the straps an so on... getting the right trim is the way to speed, and expecially to handle chop.

Iīm 190cm and 86kg, so you have to take that in to consideration regarding trim.

I use the middle hole on the front strap, and the front hole on the back straps. I have my boom fairly high.
Start with the mastfoot in the middle, stop and move the mastfoot back 1cm at the time untill you are flying of the fin but still in control.

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?

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.
Mark H.
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.
