There is little or no girth groove on this type of horse and when coupled with a powerful, well muscled shoulder this usually causes saddle to slip back. It is advisable to use a breast girth or a hunting martingale to anchor the saddle in place
This happens in both flat backed and high withered horses, but the horse which is competition fit and has little or no belly is the most prone to this. A powerful well muscled shoulder will incline the saddle backwards in any case and when the horse runs up light from the elbow backwards it is difficult to girth adequately to prevent this. A small shift backwards and the girth loosens causing the loss of any anchorage.
Minimising this backwards movement is essential -careful flocking, a panel with quilting stitches just in front of the points of the tree all help to free up the shoulder.
A significant advance in the stability of the saddle is a feature of many of NSC Jump and General Purpose saddles. We have created a design where the points of the tree are left on top of the panel ("floating point") so that the part of the flap where the rider's leg is in a shorter stirrup scenario can move quite easily without destabilising the rest of the saddle
Saddles with this feature are The Advanced Competitor, The Event /Hunt saddle, Mark 2 and Mark 3 The New Grandee, The Nyala, The Pony Pro
