If I put the kite near 11-12 my foil starts to raise from water..
Sheet out to maintain ride height as the kite comes overhead, then when you feel yourself slow suitably, sheet back in to repower the kite and ride slowly with the kite high. The bar is now your ride-height control, out=down/in=up.
If I keep it down it keeps running forward.
Yeah, any time your pull vector is in a forward direction the foil wants to go fast in order to keep your ride height stable. As the kite comes overhead and begins carrying your weight, it unloads the weight off the foil and allows the foil to carry you at a consistent height but lower speed because the kite is sharing the work.
I find that when I'm doing a max speed run, it's usually downwind with the kite barely above the water, when I need to slow down I begin by steering the kite upwards and riding towards the kite, i.e. underneath the kite in order to reduce the line tension. In order to keep the kite from crashing as I slack the lines by riding towards it, I gently start steering the kite up to 11 or 12.
So again, here's the acceleration-through-deceleration sequence:
Cross-wind, begin diving the kite.
As the foil speeds up and you begin rising out of the water, head towards the kite to slow down by releasing some line tension.
Carefully balance line tension with speed by heading towards/away from the kite at your desired speed and angle. The bar does less here to manage ride height than controlling line tension with your course and speed.
As you begin to slow down, head gently towards the kite to release line tension and reduce apparent wind.
At the same time, begin gradually steering the kite up overhead.
As the kite comes overhead and begins pulling upwards, sheet out on the bar to prevent yourself getting yanked off the board.
Maintain line tension during this deceleration by gradually heading back upwind as the kite comes overhead.
Once stable on your new course, "give-away" your kite pull in the upwards direction through the harness and transform that into forward speed (and therefore lift) by bringing the kite back down towards the water to accelerate and gain line tension...repeat.
