Howdy,

Been sailing for a few years now, but lately I've been experiencing, in chop mostly, that my front foot is pulled out of the footstrap when I'm nicely powered up.

I've lowered the boom and that does help, but I'm at the point now that if I lower it any further I'll lose power.

I've messed around a bit with the lines too, it helps a bit but I'm looking for some trick or solution that can help me out a bit.

The board that I'm currently experiencing the problem on most is my iSonic111 (07), riding a 8,3 Severne Code Red.

So, anyone got any suggestions, any pointers or own experiences to be shared, losing the front footstrap while overpowered in chop is... interesting :)

Thanks in advance y'all!

Many iSonics do this, including my iSo 94.

Perhaps you might try moving your back footstrap backwards, use a more upright fin (if using a weedy), or do what I did and just get used to it

Haha, I've tried getting used to it, but I'm too stubborn and headstrong for that.

Back footstrap backwards, I'll check if there's enough room. I'm using weedies and pointers depending on the conditions, problem with both types, but honestly I cant remember if one is worse than the other.

Thanks for the suggestions, if anyone else feels like chiming in, please do! :)

I used to have problems with my feet getting out of the straps, especially when jumping.
What helped me was that I put the screws closer together, making the strap tighter side-to-side. I also made the straps larger, so I get more of my foot in.

Good point, I'll give it a try too. Thanks! :)

I had the issue myself with ISonic 111, 09. To be honest I cant remember how I got around it and it's been a while since I've sailed it..wind.. However the board works well when driven hard of the fin.

My track is a far way back (back third). The further you go back, it will allow you to run a higher boom. I run my boom at around nose level.

Harness lines, move them back a little and go longer and move your body weight forward more (as you would when pinching upwind). I found that moving the weight forward helps to keep the pressure on the front foot and allows more mf pressure.

Not sure how it goes on the iSonic, but I tend to pull my toes on my front foot up (consciously), and point my toes on my back foot...keeps the board level too. Otherwise, tighten your straps or wear grippy booties.

i have a 2008 sonic that i never use for fear of front foot coming out of strap esp happens in bigger chop and increase in speed.

putting back straps to front position + front straps as far back as possible, this will result in a narrow stance.

i found this helps best.

other thing,i did this on another sonic52 is get new front footstraps box put in, positioned more parallel and further back.

this helped heaps and going to do on 2008 sonic.

i have a windtec and same thing happens,but other windtec no problem.

sonic seem to be the worst for this happening,f2 + kinetic found no problem.

Very interesting indeed, I've had no problems really on my F2's, only the iSonic.

@Waiting4wind:
For me, higher boom/long lines results in an even more slippery front foot. When you say moving the track backwards, are you really meaning backwards? not forwards? :)
On moving the lines further back, this is what I've been messing around with lately, I'm sure that it has helped any, but 'something' is definately happening :)

@Sailhack:
This is the natural reaction on my part too, problem is that chop WILL kick my foot out of the strap eventually. I'm not wearing the most grippy of boots, but they're fine on other boards. I've played around with different types of footstraps (currently I'm running the big broad NP-Formula thingies) and the problem is the same. Tightening the straps will result in me not getting the foot into the strap at all :)

@petermac33:
Creating a more narrow stance, interesting, that might actually do the trick! I'll try it out! As for changing the footstrap box, if it comes to this I'm getting a new board! :)

Thanks y'all again for the feedback, I'm somewhat glad to see that I'm not the only one with this 'issue' :)
Keep it coming!

It sounds a bit arse about but it works for me. It took me a while to get the lines longer but it has helped with my stance, board trim and speed. With the longer lines I can keep the sail more upright. I think the more upright rig helps to pull the power down through the mast for more MFP.

Moving the track back helps me drive more power into to the fin. As the fin provides more lift it actually helps to lever the nose down. I'm not sure how the mechanics work but if you think of it as having pivot point between the fin and MF. Push up on the fin or press down on the MF and the board rocks forward.

I agree that if you just raise the boom your front foot gets light, but moving the track back reinstates that balance.

I did a GPS experiment one day bumping track back and raising boom, moved the speed from 28 knots to 31 in the the space of a few runs. That convinced me that it was working.

hehe, you can't argue with succes! :)

I'll try moving the track back and get back to a higher boom/longer lines.

And I promise, only one chance at a time ;)

Thanks again y'all, I'll let ya know how it all turns out!

apart from obvious trim issues - boom too high , mast foot too far back, knuckle in the sail above the boom(due to incorrect rigging / incompatible mast usage) , unbalanced harness lines


alot of crew actually run their straps way way way too tight.

This results in loss of board feel and control

you want alot of your foot to be in there - not just the toes.

this gives you dominance over the board and full on control especially when it gets choppy. Control is where the speed lies - not a little bit of extra leverage.

If you want to get your feet real cosy in the straps you can even look at going slightly smaller in fin size. Thats a personal thing - i like to run the smallest fin possible.

I have had the same 'front foot coming out of the strap' problem on my ISO 105, at times I have wondered how I could have ever sailed it. Although I am fairly tall I have to run my boom lower than may be expected to prevent this.
As for moving the mast foot, I find I generally have to have this a long way back to get any ability to point (I use weed fins almost exclusively) so moving the mast foot to prevent front foot from constantly being driven from the strap is not an option.
How much of my upwind problem relates to poor technique I cannot tell

I had not thought about it being a sonic/isonic issue before, I do not have the problem on my old (circa 2001?) Sonic W52, however that may because I always run the boom low
