Riding with Charlotte's new video of the course hire is horrendous.
Starting off when they're just warming up, the sitting trot in particular was awful, Vossi is trying to open his mouth to release pressure but is unable to do so because of the grackle, he also lifts his head to try and brace against the contact regularly and as seen at 8.45 and other moments twists his head to try and get away from the pressure. The tail swishing he does as well is another sign of discomfort.
Charlotte's position in sitting trot is awful, granted its quite difficult in a jump saddle which is why its not really a done thing, but because she is unable to sit the trot properly her body is completely out of alignment and she's ended up in a chair position with her upper body leaning even further back. All the sitting trot achieved with Vossi was to actually make him more hollow as he is uncomfortable and doesn't relax and work over his back properly.
The actual jumping is painful to watch. Charlotte gives so many mixed signals with her body and aids. Maybe this worked with previous horses she's had like Amber (?) who were more your point and kick horse but its definitely not working for a sensitive horse like Vossi.
First of all there is no rhythm at all. Charlotte rides in a hold and push style which doesn't suit Vossi. He needs to be able to be in a relaxed rhythm and its just not. Where are the placing poles, ground lines, etc... all the sort of things that would slow him down? Whilst I recognise that you don't have canter poles when you're out competing I think based on their last show they are a long way off from worrying about that. I honestly don't think they work as a partnership and don't trust each other and this shows in their jumping.
Further onto Charlotte. Her hands. Moments like 10.01 are horrendous. There was no reason for him to be sawed in the mouth like that. Funnily enough it ruined his rhythm, then she tried to fire him at the jump, and having just been socked in the mouth by her he refuses it. She often doesn't give very much over jumps either and I think on a horse so sensitive it is not helping.
However, whilst her hands are saying stop, her seat is pushing him forwards all the time with a sort of scooting motion instead of actually sitting in her seat properly. You can see a few strides out her literally firing him at the fences.
Also her legs are pushed forwards and braced against the stirrups. This is not a relaxed leg. Vossi will feel this tension and combined with the hands saying stop and the seat saying zoom must make for a very confused horse.
If her goal is to get round a British Novice BSJA, then I think she needs to go completely back to basics. There is no point trying to jump courses of height when the basics aren't there. Short, fun sessions is all he needs and completely back to something as simple as scatter poles. She needs lots of lunge lessons, probably not even on Vossi but to pay to go somewhere for that, to work on her position so she is as balanced and settled as she can be.
But of course lets post on our story about how the BSJA legal jumping baton is your best friend because that's going to create a horse who trusts you enough that you're going to work up to jumping anything of a good height out showjumping.
