What is it supposed to be achieving?
I read it, the interceptor is a lip on the back of the transom. Some IMOCAS tried these but had ones that moved. Tele's is fixed. Before the start they were removing it from pictures with photoshop.
The moving interceptor is based on the principal that you can control trim. You build in a bit more rocker in the shape, so it more easily lifts the bow in heavy downwind stuff. But, that leaves you potentially with a sailing trim in other conditions that is stern down and slower. So you induce a moment to level the boat, at the cost of a small amount of drag (induced if using trim tabs/foils, direct drag with an interceptor) This drag is worth it because the overall drag of the boat is less, wake far cleaner visibly.
If you search for E-cover on this topic you will find video comparisons of with and without.
I cannot see the way a fixed interceptor would work at first glance. I guess you may be able to trim it out of the water with stacking forward in the really light. And set it up so that is ineffective at producing a moment when heel is on. I had
thought it might not fit in the no hollows rule. In VOR v3 this states clearly transverse plane only. So they must have created a kind of edge aft, probably on CL, that can be pulled from the water with heel, therefore allowing the hull to pop the bow up a bit better.
