1. A boat hull, comprising: a boat hull having an exterior surface, with at least one step surface portion defined therein which changes the configuration of a lower surface of the hull;a support system comprising a channel or flange support assembly which are fixed and extend substantially parallel longitudinally of the hull a selected distance from a start point which is located toward the bow of the boat; anda member positionable in the support system, wherein the member is movable along the support system wherein the channel or flange support system are open at an aft end thereof, wherein the member is supported to be movable along the support assembly approximately parallel to the hull of the boat and wherein a stern end of the member forms a step surface portion and can be fixed at selected locations along the hull, including beyond the aft end of the open support system or flange support assembly, thereby changing the position of a stern end of the movable member and hence the position of a step surface in the hull surface. 2. The boat hull of claim 1, wherein the flange members support the movable member below the hull surface. 3. The boat hull of claim 1, wherein the channel is closed except for the ends thereof, and extends all the way to the bow of the boat, with openings at the bow to the atmosphere, thereby venting the channel along the length thereof, permitting air to flow through the channel to the step surface. 4. The boat hull of claim 1, wherein the channel is closed except for the ends thereof, the channel opening to the sides of the boat and the atmosphere rearward of the bow, thereby venting the channel along the length thereof. 5. The boat hull of claim 1, wherein the boat hull has at least one fixed step surface therein at a selected position along the hull, wherein the channel extends from the fixed step surface. 6. The boat hull of claim 5, wherein the boat hull includes more than one fixed step and a channel associated with each fixed step, and further including a movable member positioned within each of said channels. 7. The boat hull of claim 1, wherein the movable member has a curved lower surface. 8. The boat hull of claim 7, wherein the lower surface is concave. 9. The boat hull of claim 1, wherein the movable member comprises two separate portions, movable together or independently within the channel. 10. The boat hull of claim 1, wherein the movable member has a lower surface defined by a series of steps. 11. The boat hull of claim 1, wherein the movable member has an angled lower surface. 12. The boat hull of claim 1, wherein the movable member is positioned outside of the boat hull, adjacent the hull surface. 13. The boat hull of claim 1, wherein a portion of the movable member is positioned within the hull and the remaining portion outside of the hull. 14. The boat hull of claim 1, wherein the boat hull is a hydroplane, having two spaced-apart hull portions, and wherein each hull portion has a fixed step surface, a channel extending from the fixed step surface to the bow of the hull portion or to a selected point to the rear of the bow, and a movable member positioned in the channel, arranged to be supported at selected locations longitudinally of the hull, thereby defining an adjustable step for the boat hull. 15. The boat hull of claim 1, wherein the boat hull has a tunnel configuration, with two spaced outer depending portions and an intermediate portion, and wherein each of the two depending portions includes a fixed step surface and a channel which extends from the step surface to a bow end of the hull portion or to a point to the rear of the bow end, permitting air to flow therethrough, and further includes a movable member positionable therein, having an adjustable position defining an adjustable additional step for the hull. 16. The boat hull of claim 1, wherein the boat hull includes two side hull portions and a center portion, thereby defining a tunnel-type hull, and wherein each of the side and center portions include a step surface therein and a channel which extends from the fixed step surface forwardly of the boat and a movable member positioned therein, a stern end of which defines an adjustable additional step for the hulls. 17. The boat hull of claim 1, wherein the channel extends across a portion of the hull. 18. The boat hull of claim 5, wherein the channel extends across the entire hull.
