Wakeboard Tantrum

[AJ]

My name is Andrew and I'm 16 years old.  I've been trying to land a Tantrum on a wakeboard for 3 weeks but can't seem to land it.

I think I'm landing either goofy or in a butterslide everytime.  Would you have any idea why?

I'm wakeboarding behind a 1984 2001 Nautique without any tower.  Might this be my problem?  Is it even possible to land it without a tower?

I must have tried like 130 times but can't seem to get it.  If you could help me that be really awsome because summer is almost over and I want to land it so bad.

I'll post a picture that might help.  I'd be grateful for any help you can give me.
 
Thanks, Andrew

A video would help a lot more, but from the picture the thing that I can see is that you are holding on with both hands.  You should let go with your back hand to get the correct rotation.  The flip you are doing right now is probably closer to a heelside frontflip (and likely to a "Frantrum" [frontroll tantrum]).  Let go with your back hand just before you throw the trick.

You should be fine on your Nautique, it is definitely possible to do inverts on a boat without a tower.  A tower would help, but it's not necessary.

Hope that helps!

Cheers,
Brad
