View Full Version : Isonic 111 - Fins

17th October 2008, 01:21 AM
Oh dear, I'm sure this question comes up all the time!

About two months ago I finally broke down to the pressure of my windsurfing buddies and went out and got a 2007 Isonic 111. Looking back I should have done this a long time ago but hey, I dont like getting bossed around ;)

The board is fantastic and the two fins that came with the board (36 and 42cm) have proved servicable so far. Having gotten used to the board I am now in the process of figuring out ways to get the board go faster (yes, I am one of those people who loves going fast, or at least faster than my buddies).
My 'weapons of choice' at the moment (not my choice really, more a question of finances) are a NP V8, 8.0, and a Ezzy Infinity 6.5. I realize that these sails might not be the absolute pinnacle of speed-sailing technology, but at the moment those two sails will suffice.

My question is this: What fins (preferably two) would increase my speed on the 111 Isonic (2007) with the two sails mentioned? What brands... models and sizes would help me go faster. Ofcourse control and upwind-sailability is of interest as well, but not the primary goal here; beating my buddies on the other hand, is vital :)

So, has anyone any experience with the board/sail-fin combination that I have here, then any help would be much appreciated!

Oh, almost forgot it: I'm around 85kgs, 1.80m tall and sail in flat/slightly chopped water in anything from 15-30 knots.

Thank you very much in advance!

Hi Malloy,
I tried a lot of different fins. First MFC, which are fine. Sometimes a Deboichet, which feels super powerful and should be great. Most of the top ranked PWA SLlaom 42 sailors use them.
Nowadays I use Vector fins, the CF (canfire) model. I would recommend 42 or 40.
Enjoy sailing,

Yeah, I use also Vector Fins Model Canefire 38cm for 6.3m, 40cm for 6.6m, 42 for 7.6.
So far that is my biggest sail in that board iSonic 111 2008.

Thank you so much for the swift replies.

I've emailed Vector Fins for size recommendation, price and availability.

If anyone else have any experience and information they would like to share in regards to fins for my Isonic 111, please feel free to post away.

Again, thank you so much for your advice, much appreciated! :)

Vector for the price has no comparison.. You will be happy with how they work. Jasper Orth is their team rider and rides for startboard he was the one who recommended Vector.
$195 for sizes 38cm and under and $205 for bigger sizes than 40cm. Hope you get to buy one they are great, Also your board will stop spinning out like with the original fins the boards comes with.

Hi nonopro and malloy,
that spinning out topic is important and I really felt the same. Very seldom a spinning out. Amazing. I am also surprised how well bigger sized (38+) G10 fins work.

VEctor fin should include me on the team. I have given them so much good marketing.

A followup post would be in order.

Good and bad news (well, no news is bad news in this case).

I had the opportunity to try out a MFC RC 40cm fin on my board, and wow what a difference. Not only did the amounts of spinouts drop, but the board felt much more at ease at higher speeds. Soon I'll be able to try out the 44cm version, but ultimately I would like the try out 36 and 38s.

That was the good news, a positive experience with MFC. The negative news, or complete lack of news, is that I, as I mentioned last week, mailed Vector Fins for availability and prices and have heard absolutely nothing from them, no response, no automated message... nothing. Its too bad, and a little bit irritating since I really wanted to try out one of their fins. I'll give them a few more weeks to respond, but after that I'll probably just give up and spend my money with MFC.

Again thanks to y'all for your feedback! :)

Hay Malloy,
don't waste your time and buy 2 Tectonics Tomacat (40-38).I use also a 42 in very little wind for the size but the secret comes from the balance between sail trim/fin size/boom height/mast base position.
Just put you footstraps all the way back,the mast base behind the 2nd line on the mast track,boom on chin level,put your 40 in and a good 7,8 and then you MUST push as hard as you can.Later you'll find some true speed...

Hi Malloy

I have sailed the 09 111 Isonic for some weeks now, with different fin combination's. I noticed that we are very close to be the same height and weight, so I thought you might find it interesting in what set-up I find good.

If you are after 2 fins then I can strongly recommend the Vector Fins Canefire G-10 model in 42 and 40. For sure those will give you a step forward in speed and control.

Hi Jesper - I just picked up an 09 Isonic 111. Great board, I've only spent a few hours on it and I have found it easy to get comfortable on quickly, moreover it's improved my gybes significantly.

Keen to hear how you've set up your board and any recommendations you have. BTW, I'm 90kg and primary sail is a NP RSS 7.8.

Thanks guys for the email to Vector Fins, I am not sure that was the one I found on their website, but I wrote Jeff once more and hopefully I'll get a reply this time.

I will be looking at getting 2 fins (hopefully CaneFire fins are available!) sizes 38/40, 40/42 or 38/42; I am guessing that 38/42 would provide the greatest flexibility in sail size.

I've been wondering about this. My 07 Isonic came with two fins, a 36cm and a 42cm, but it seems as if most people tend to use the larger fins in general. I've had some success with my 36cm in slightly overpowered situations, but should I just stick to the larger sizes and ajust the mast-foot acordingly to compensate the extra lift ?

Hi Malloy

Your right about your observations on the fins, most sailors uses the larger size fin, which follows the board. The 42/38-fin option, sounds good for the 111, this will cover everything.

Small update:

I got ahold of Jeff from Vector Fins, made an order and now I have two CaneFire fins in the mail, 38 and 42 cm. Cant wait to try em out :)

Malloy, please give us a report on you're new fins when you've given them a run.
