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 
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.
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!
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.
