Default Isonic 09 double wingers

Question for Ian or SB team,

Can u give us some insight on the double wingers for 09 isonics, as in what purpose it serves? It looks like the tail section after the double wingers is narrower.

Thanks.

My undetsanding is that the said max width of the board is mainly to creat lift to get the board initially plaining. The wingers at the back ensure's the board has less width ie contact with the water so greater speed potential and with the possibility of slightly eaier gybing.

Double wingers are just a way to have a specific width distribution over the board's length. Can do that with double wingers, like Aquata was doing in the '80s, or with a nicely tapered outline. Double wingers have one specific advantage over a smooth looking outline: they look weird and technologic. Great for marketing.
The real news seems to be that the iSonics needed some width reduction in specific areas.

Just my view, of course. Ready to change it if someone provides good explanations. Current explanation in the iSonic page ("The theory behind the concept: ...") just says that boards work better when they are wider in the middle and narrower in the tail...

Hi Philsurf,
I did not sail the 111 so much, but guess that the board works greta with sail from 7,0 to 8,5. I also sailed a 9,0 on while testing an it worked quite good. Antoine i susing the board with 7,8 a lot I think.
Concerning the finlength: it always depends which product you use, how powerful the fin is. I would suggest 40 -42 (44 with 9,0).
Perhaps someone else can come up with further notes.
All the best Phil,
Chris

iSonic 111 2008 with 6.3m2 38cm fin. 6.6m2 with 40cm fin. 7.6m2 with 42cm fin and 8.4cm 44 cm fin. I have not sail this board with the 9.2m2 I have but I will use probably the 44cm fin.
All sails are MauiSails TR-3 and TR-4 and Vector Fins Canefire.

Nonopro,
thanks. That sounds excellent. The canfires from Vector work great on the Isonics.
