RE: Q - Isonics & Jibes
Speed is your best friend here.
Are you going scary fast on your reaches?
If so, jibing will be easy if you figure out how to keep your board trimmed (fore and aft) at the same angle or attitude into and through your jibe.
If you move too far forward, the nose drops and your speed drops.
If you stay too far back, the nose pops up and your speed drops.
So, anything you can do to maintain speed will help alot in yoiur jibes.
The Isonics are quite sensitive to pitch (fore and aft) angle of attack (AOA) so yo must find the sweet spot to place youir foot on the lee side as you change the boards "roll angle" to initiate your jibe.
Again, get the foot a little too far forward, the nose drops because your weight is too far forward and you've changed the pitch AOA.
Get that foot in the right place, steadily and progressively add weight to it so the board changes roll angle smoothly and you won't loose much speed.
Also, if you are not really powered up and going scary fast, forget about "over sheeting" on the entry to your jibe.
Yes, oversheeting kinda "draws you in" to your jibe, but it also slows you down. Unless you have "speed to burn" anything that slows your board tends to spoil your jibe.
If you keep a little power on as you enter your jibe, and unsheet your sail in a manner that keeps a little power on (to keep feeding mast foot pressure to keep the nose from popping up suddenly), your board will roll into the jibe and you will have a little "pull" from the rig all the way until you are ready to flip the sail.
Keep carving with the board at the same pitch AOA, flip your sail without upsetting the the AOA or the roll trim that's taking you around the jibe, and you will power up on the new tack.
Flipping the sail as early as possible is good.
Hope this helps,
