On my new 9’6 I put quite a bit of rolled vee in, starting forward of center and becoming gradually more so through the up rails in the tail. The rails are downish in the nose and neutral middle. I may have put a little more than I wanted, and started wondering what made this different, or similiar to, a displacement hull. Can anyone help out with this, and also I’d be interested to see how you think it will work. Thanks- gill
Generally speaking, if it doesn’t have concave, it’s a displacement hull. I suppose you could say a truly flat bottom is a planing hull, but essentially, if it’s got roll at all, it’s a displacement hull…unless you’ve got concave under the nose. As you may know, concave creates lift using the air between the water’s surface and the board. Thie board slides or “planes” on this. This process is called planing. Just about anything else, particularly a bottom with any amount of roll, pushes the water out of the way or “displaces” it, thus creating a smooth platform of water on which to slide. It shapes the water to its ouwn curves. This is called a displacement hull. Sounds to me like that’s what you’ve got. A 9’6" displacement hull is the classic noserider. It should be stable and forgiving. Rolled bottoms may turn a little slower, but this gives a nice smooth feeling to the ride. My advice in riding this board: Don’t push it. Relax. Feel the glide. Also, here’s a cool thing to try if you haven’t already: Depending on the width, maybe play around with riding parallel stance, meaning, toes facing foward, instead of a fore/aft stance. It’s a really cool alternative and gives a great feeling of glide…deeb…
