If you are set on getting a iSonic, I would go for the iS155 with a 9.5-10m2 sail. I have an F-Type 148 and use it with a 9.8m2 V8. This, with a 70cm fin, gets me going very early. I weigh 65kg. A formula board would be better suited, I would think, but the iS155 is a sharp machine. I gave one a try in the spring and found it was a step up from my F-Type. I get my F-Type planing in 9 knots with some aggressive pumping.

85Kg 8kts, iS133 9.5 planing! So what about a 65Kg guy?

Guest#1,

I would say get an iS122 with a 8.5-9.0 sail to plane as of 9 knots for a 65 kg body weight.

I'm 65 kg as well and I can plane on iS133 (or HS105) as of :
- 7 knots with a 54 cm fin and NP RX2 10.6 sail;
- 10 knots with a 48 cm fin and a NP RS2 8.2 sail.

Larger board do require bigger sail and bigger fin to overcome drag. For a 65 kg light weight sailor, I've witnessed on several time that it's not really necessary to go up to iS155 or FW to plane as of 9 knots IMHO. This is a different story for a medium or heavy weight of course...!

Cheers !

c'mon honestly 60 Kg and an iS122 with a 8.5-9.0 sail???
I thought more like iS101/iS111 and a 7.5 sail. Anybody have same parameters (60Kg and >=9Kts)?
