Generally the swim deck needs to be just under the water. I haven't measured how fare under the water it actually is <flow> but I can say more then a foot is too deep.
When we roll goofy we are sunk really deep on the goofy and this allows the flow to now sit as deep and it works great.
On a limb I'd say don't sink it more then 12inches under water when you measure from the top of my flow bracket. Not the arm its self.
