Default RE: Q - Isonics & Jibes

Hi Daniel,
Where to place your foot is very much an individual thing.
Some of the variables that make it so "individual: are:
Your weight.
Mast foot positon you prefer.
Your stance.
The size and weight of your rig.
It's not a bad idea, when you get a few fully planing carve jibes on your board, to put a piece of tape or something on the rail of your board so you have a "visual" on where the lee rail pressure needs to be applied. This will be approximately at your individual "sweet spot".
If your jibe works well, take a quick look and see where your foot is relative to the tape marker.
If you don't plane through your jibe, take a quick look (when you're sure it's hopless) at where your foot is relaive to the mark. Then you can move your foot a little forward or aft to compensate on your next jibe.
After a bunch of jibes, you will develop a "muscle memory" and no longer need the marker.
If you have jibed smaller boards with softer rails successfully before, you probably are going a little too far forward.
Smaller boards with softer rails require you to "engage" alot of rail to complete your jibe. On the Isonic and other short. planing flat at the back, boards, this normally results in your applying your weight forward of the sweet spot, and your nose drops, which effectively
flattens oout your AOA to the point the board "trips" over the rocker transition at the front of the planing surface.
I'm pretty sure I go just slightly ahead of 1/2 way between the front and rear footstraps, but I'll need to take the Is 122 out this weekend and double check on where the "sweet spot" is for me on that board.
Your "sweet spot" may be slightly different.
If you "release" your sail, without getting the mast upwind so the rig balances pretty well on the mast foot, you will most likely be filipping a bit late.
I think it''s better to bring the rig up a little past vertical (where it balances on the mast foot and will "spin" to the other tack very easily)
and the pull with the front hand and push a little with the back so the rig rotates quickly. Then catch the mast or the front of the boom on the new tack, and drop down a little as you begin to power up on the other tack.
Lot's of ways to do this..... none of them is all that much better than the others, it's (again) an individual thing that you need to figure out for yourself on your board with your rig. It can vary a bit with boards and different size rigs, but you'll get the hang of it pretty soon.
Try to get your board carving around the jibe first, then work on timing the sail flip, then work on footwork. Break your jibe up into a few "stages" so you can work on getting each of them right, then getting the timing right so that your jibe just "flows".
Hope this helps,
