View Full Version : front footstrap feet comes out,

1st April 2007, 02:53 AM
hi there ,
after 27 years of windsurfing ........i have a new 1sonic 100
today i sailed it in holland with naish stealth 6,5 and the board go's
like hell,i never expierienced this speed and control on the board and the sail,this newer material is really really a lot better ,
Although i had a perfect day there is one thing,i had to lift very hard on my front foot to keep the board in control,this resulting in a cramped foot,or adjusting the strap in to small or to bigg,
Who can give me a suggestion to look for???
Thanks a lot in advance

try lowering your boom

Not specific for the iSonic 101 (?), but you could try moving the mastfoot backward, this will lift the nose so that you don't have to lift it with your front foot. Raising the boom will also have a similar effect.

Front foot comming out is a matter of tuning (mast track position, back hand power). To reduce this effect you need to reduce the pressure at the fin. I'd say move mast to front (not like Krister says) and lower boom. Play with boom tension to get the perfect one for the day. I advise outhaul trim system.
Also the fin itself could be to big and powerful for those conditions.
all best

I agree that if the foot "accidentaly" comes out of the strap it is probably due to too much backhand pull and backfoot pressure, but the writing "i had to lift very hard on my front foot" to me sounds like the nose of the board rides to low?
And the remidy for that would be mastfoot back, boom up etc.

I have a lot of experince with that as an owner of SB HS.

-Lower the boom
-More Downhaul
-more Outhaul
-Masttrack a bit forward
-Move the front footstrap a bit backwards, more power on the frontfoot

And the most important parameter:
-A sail with stable deep forward, draft profile

With regards,

Thanks a lot for the replay's
today i sailed again in holland (grevelingen)and after adjusting some settings things are a lot better,
I placed the mastfeet backwards ,gives lift and felt a lot better,also
more downhaul was improving,less backhand power by moving the
lines backward also helped,
I think i'm on the good way ,i also changed the foot strap position ,
backstraps more front to get more weight forward....

Best regards,

That last one seems to be key... putting your backstrap a little further forward (or as far forward as poss). I was reading one of your Dutch magazines recently and Martin van Meurs (him of going fast fame) identified a ''hovering front foot' as an issue with some boards.

His advice was to put the back footstrap as far forward as possible when you are still getting to know the board. As you get more familiar it may be possible to move it back a bit.

He suggested that because manufacturers design slalom boards according to the demands of their W/C sailors (Albeau, Maynard etc) who are all pretty big guys, the standard settings for the boards reflect this, which means that if you are not 6''4' and 200 pounds your settings will likely have to be narrower and further forward.

Having your backstrap further forward also improves the feel of the board - it makes it a little more polite and less on edge. Outright speed however is improved by having them further back. But then speed is nothing without control, hence the 'get to know the board' first.

still having the same trouble on the front foot,
this weekend i sailed on the starboard and on an F2 custom speed board,both with the same rig,a naish stealth 6,5 meter.
It was very clear that the problem of the fornt foot comingg out of the front footstrap was less on the F2 board,while the trim of the rig was exactly the same,
Not that i didn't get going,, the speed was good but could be better.
I have to constantly lift my front foot on the front strap and have to pull very hard with the back hand to keep in control,
Now does anyone know what to do???is it the sail trim??or the board trim
(masttrack more foreward....)
A big thank you for any answer in advance!!!

frontfoot position is different on other boards.

Bigger sail helps out with frontfoot problem.

Lower boom
Forward mastfoot also
Distance between footstraps has to be smallest, in beginning.

But for speed you better take smaller board, or in less wind bigger sail.
