Great, your daughters board has enough lift for her size - there is air under it however her feet are way off.

First thing she needs to move her toes closer to the wave (toe side) of the board, this helps the board grip the wave and turn lift into forward movement.

Second she needs to bring her front foot further towards the front of the pad.

Third if she holds here back arm out over the wave, this will put even more pressure over her toes converting more wave energy into forward momentum.

Finally if she puts her other arm pointing towards the boat that will also help.

Good news is between your current wave and the board she is on, there is plenty fo lift for her to go rope less.

Three small changes that make a massive difference and will almost certainly get her dropping the rope next time out.
