max sail size Isonic 111.

[johant]

What is the main difference between the isonic 111 and slalom board with a width of around 70 cm.
Other brands with slalom boards around 70 cm width is the max sail size about 8 meter(f2 sx m) and the isonics 111 can carry a 9 meter as biggest.
I hope that every body understand mij question because mij English is not so good.

Hi Johan,

The main difference comes from the planing area /tail width (tail area) which allows the iS111 to carry more sail (and importantly big/ger fins, to allow efficient match to the larger sails).

In fact, SX(m) @68cm wide is rated at 8.5m sail max by F2, so a 9m rating on the iS111 is not that much different in reality.

iSonic design allows use of a high/er aspect ratio (more efficent) planing surface area at the back, while the control, comfort and jibe etc remain really first class (something that normally gets compromised with a wider board or wider tail area).

Hope this answers the question, please let us know if you need more info etc.

Cheers ~ Ian

Is a board with a widther tail More difficult to control in his higher wind range than a board with the same width anly a smaller tail.
Is the 9.0 the biggest or is 9.2 possible e.g np rss 9.2 for a 80 kg surfer.

I haven't tried a 9.0 on an iS111, but I use it on a 70cm wide JP slalom (it can be used, but it's not "the sweetest" size). I'd guess a 9.2 will be too big, and even if you use 9.0 very often, go for a bigger board. If it's mainly 7.x sail with the occasional use of a 9.0, it may be OK.
