Which Isonic ?

I would like to buy an Isonic to replace my 80cm slalom board but I'm still hesitating between two boards : Is 122 (07) or Is 133 (07)

I'm very heavy (117kgs) and I have a F162 for winds below 15 kts.

The board would be used only with 8,4 (maybe later 9,0) in winds between 15 and 20 kts.

Which one would be the best one to choose ?

Best regards

iSonic 133 for you.

Hard to recommend for your weight, not many windsurfers heavier than you eh?
I use a 122 and like it (I'm 86kg), you could get away with 8.4 as your largest sail for it, but you'll sink like a stone in the lulls.
I would say 133, but heavyweights should chime in.

The problem is that a 80 cm board is a pain in the ass on my spot with 18/20kts of wind. It is not flat at all, very bumpy instead ....

I have a 80 cm board (AB+ 80) which is much too big for my taste with 8,4.

I do not sail 8,4 in sub 15kts conditions, I go for F162 with 11m, that's why I'm asking about the 122

Well it's really difficult to give advice here ..... simple scaling won't work I'm afraid (I can use an 86 lit board in steady 18-20, but still...)
If you have steady force 5 + chop, then you can use iS122 for sure (it's around 115 lit real volume). But if it's that lumpy on your spot (and 80cm board is a pain in the ass), there's a chance a 75cm slalom board won't be very sweet either (although to be fair iS122 is excellent in ignoring chop - up to a point). Perhaps a different type of board (futura, kode)? But then again you probably need that 8.5 to sail efficiently when smaller people are on 6.5. It would be best to try some boards if you can. Have you sailed smaller boards in coastal conditions?

I'm guessing a lot obviously, heavyweights where are you? ;-)

Hi..
At 95 kgs I'm heavy but still that's 22 kgs less than you ;-)
I have an iSonic 122 which I love for 8.5 down to 6.5 m2. It's not too floaty and at your weight it will be a sinker in lulls. The '07 IS 133 is only 5 cm wider and it will carry you a lot better. I don't know your old 80 cm board but these new designs are seriousely well sailing even in choppy and windy conditions. The reason I bought the 122 is that I sail in an area with very gusty winds and chop where I need a board with a HUGE range. I can blast my 122 way into smaller board area even with a 6.5 and it goes through lulls easily. Maybe not ideal for competition but if the wind changes a lot average speed may come in favour of the bigger board.
I would go for the 133..

I`d agree with Per.Go with the 133.(But ???)
I`m 103k (+/- a couple of k!)
I have always used 130 litres as mid wind board. (ie 6 to 8 metre)
I think even at my weight I`d be opting for 133 for wind/sail size you mention.

My mate (112 k) uses go 160 for medium winds.(6.5 to 8 metre) His "small" board is a Hornet 135. He flies on that and matches smaller folk on dedicated slalom kit. (once its blowing) (Suppose thats recommending Futura 133??? Just a thought?)

I`ve found dedicated boards are not that much (if anything) faster top end than easier sailing (narrower!) boards for heavies in conditions we end up on them in.If that makes any sense .?? Big blokes really can make such as Futura`s really go.(You would sacrifice something though)

Its really important you try all boards you are considering.Only folk that can actually recommend anything for you are those of similar (same?) weight (and ability) and sailing at simillar venue.

Ignore quoted sail ranges aswell.They are nonesense for heavies.(Sweet spot for my 105 litre board is 5 metre.(with me on it).Its quoted sweet spot is 6 metre; which is bordering on too big for board for me !)(Would be worse for you !) (Again if that makes sense!)

Good luck..

Try them all. Be patient.

I'm thinking to sell my F162 because it'is too technical on my local spot. What would be my best option then ? Is144W85 or Is150 ??

Target sails are 10,0 and 8,4, sailor 117kgs ....

150 I think.

Or futura 155, not bad either ...
