Has anyone tried the Arneson Rocker Plates yet? Just curious how well they work. I remember seeing a post by Edward Donnelly awhile ago, he said his buddy put them on his 22' Classic. Any info would be appriciated. Thanks.

The Arnesons did not increase top end,but did improve the handling. It eliminated his porposing. Very expensive though $3,400

What I'm finding out(so far) is that for boats that have a large rocker in the hull, the ability to put a hook it in with the plates dramatically improves the handling of the boat. But I have not heard much about a hull that has a hook trying to get more rocker out of it. It seems to me that if your hull has a hook in it it will always have a hook. Granted with the plates it would be less because the plates would "stretch it out" for lack of a better word. But your boat hull would still have the original "shape". I can see a small amount of increase of speed because the boat would now be riding on the plates more giving more bow lift. But it seems to me like you would have to re-work your hull to put a rocker in it than use the plates for control if you want to see big speed increases. But that's just my thoughts, and I may not know what the hell I'm talking about(again) http://www.donzi.net/ubb/biggrin.gif

OK. Now I need to get clarification on hook and rocker. Is "HOOK" what I see in the early '70's 16's? Is that where the hull, near or at the transom starts to head back towards the water? And, is rocker, the shape in the hull that is upswept. I guess, what I am trying to say here, would these hull conditions look like a pickle on the table rolled 180 degrees between the two aspects and exist only from bow to stern and not through the beam of the boat? http://www.donzi.net/ubb/confused.gif

Hook is a concave section of the hull.
(bow) _____________------_____. (transom)

Rocker is convex section of the hull.

(bow) _____________-----------. (transom)


Some hooks are designed in the hull and are good for low speeds. These are the hooks on the outer chine. They are out of the water at high speeds and should be left in the hull to stop low speed porposing.
Hook in the wetted surface of the hull, at full throttle, will force the bow down and you will need excessive positive outdrive trim to lift the bow. Newer hulls have rocker built in to the hull to lift the bow. GEOO
