Not a Naval Architect, but I have been reading a lot of such research and often it ends like this one, "it is up to the captain". What I am...

You are right again. There are stabilized trimtabs for fast boats already...:)
You are right Bill and this is also what I said in post nr 7. This combination has to be tested out carefully, but on small and not too fast...
