St Kilda / Port Melbourne

I tend to think it gets the best seabreeze-effect... not gusty at all - most folks on 5.8/6.2

guess it would depend on board width, sailor skills, weight, etc ...

the 2013 Isonic 90 is marked as having a sail range of 5.1 to 7.0
2 square meters is a realistic range ...

would REALLY like to see a clip of someone on a 90 liter board using a sail approaching 8-oh !!!!

I have used my 10.7m RS Racing, on my 95'ish slalom board... pretty silly really, but did get me planing in about 10-11kn. Could gybe it, but not planing... more of a flip'n'waterstart.

Here is some proof. reflex3 7.8m with a 2012 Isonic90 and a 36cm carbon pointer. This was my bread and butter combo for the last 12months. It works in 15-25knts no worries. Pretty quick too.
EDIT: I weigh 80kgs

I wondered the same and used my 7.8m on a 96L JP Slalom (I'm same weight) with 37cm fin and was ok 10-12knots. Bigger fin would help.

Cheers

I've used a friends 8.4 Koyote on my 95L AHD SL1 w/ a 37 fin and found it to be "acceptable"

now that is a polite way of putting it

and you guys are giving me a new perspective of the modern slalom boards !!!
with those big sails in lite winds !!!

also, i know why i have such a difficult time imagining it for myself
i weigh twenty(20) kilos more !!!
this would require a 120 liter board with a 10-oh in those conditions
someone like Antoine Albeau can do this on a 135 liter board - NOT ME !!

I reckon you have to consider water state and wind steadiness. A big sail on a small board can be awesome fun in steady winds and flat water. It can be an exhausting painful affair in choppy, gusty conditions.

I ride in port Phillip. Am 75 kg. I tried my 7.8 on my 100 l freestyle wave. Felt stupid! Awkward.

I recommend a bigger board for the light winds.

It s more fun using your 6 m on a 150l board and practicing your helitacks.

Give the SUP with a plug for your rig a go. It's more fun than you think

I'd much prefer a big sail on a small board over a small sail on a big board. Your 'engine' (sail) moves your board. Yes, if you're interested in only practising some basic freestyle moves in light winds & not planing - but that's not what most are trying to achieve. A large sail can work well on a small board when blasting on flatwater & chop-hopping, providing it's rigged right & you use a fin that matches the sail size.

There's nothing worse IMO than putting a small sail on a big board in a strong wind - my body hurts just thinking about it.

Freestyle waves are not suitable for big sails. 100L freestyle wave would be at it limit with a 6m sail. Slalom and Freeride boards are built for larger sails. Same volume (100L) slalom board can handle nearly 8m.

A lot depends on where you sail. Conditions here are usually quite gusty, average speed doubled gives you roughly the gusts, a 15 knot day will give you gusts often over 30 knots. I use a larger board with a smaller sail, typically 6 metres with a 110 litre board. You need to get through the lulls without too much sail for the gusts, the larger board helps with keeping on the plane with the small sail to keep it under control in the gusts. A lot of downhaul helps as well.

I'll add that a lot has to do with rail shape too.
Example was using a 6.6 KA Koncept on a S-Type 93 (close to 100l) with a Choco Fireblade 36 fin.
Was ok, but anything smaller than 34 fin with that and it gets harder to sail and slips a lot.
But then just for fun on a few last runs, i put the same sail on on old Windtech 8'10" (about 80l) with a Choco FB 30 fin and it was great. Rock solid and i was under powered. I could also point upwind more.
The S-Type has soft rails right back to the straps, Windtech hard rails all the way.

Thought l throw my 5 cents in l sail a traditional 92 litre r.r.d freerace board with a 7.8 north (ram).run a goldwing 38 cm fin downhalled to the maxed in ****y gusty wind 10 to 25 it works good tweak the out haul and you cant go wrong when the wind is good l much prefer t hold down a smaller sail.

I used my rs slalom 7.8m with 90l - 62cm slalom board in the pic below. I used to love this combo in rough water in lighter days when a big board gets knocked about. When I upgraded to a later model rs slalom which had more grunt the board wasn't as happy!
