Because you have deep V shaped hulls, these hulls itself have a considerably lateral resistance. So together with the rudders the total centre of lateral resistance is somewhere halfway the hulls.
You wrote that the centre of effort of your sail is just above the rudders (I couldn't check this on the video).

But that should give your cat a very heavy weatherhelm (wants to go all the time in the wind).

By the way, ther's nothing wrong with Deep V hulls. Almost every aged sailor in this forum has begun his sailingcareer on a small hobie or prindle. And they all had deep V hulls.

On waves there's nothing better
