the wetted planing surface may be automati- 1o cally varied as the speed of the boat or the load carried is varied.
Other objects and advantages of the invention will appear hereinafter.
A preferred embodiment of the invention is shown in the accompanying drawings, in
which,
Figure 1 is a side elevation showing the boat at rest.
Figure 2 is a similar view showing the boat- 2e getting under way.
Figure 3 is a similar View showing the boat at planing speed.

Figure 6 is a rear elevation with the plan so ing members turned to one side to illustrate ban-king effect.
Referring to the illustration maybe of the scow type adapted to be propelled by an outboard motor 2.
- Secured to the hull 1 in a manner hereinafter described are a plurality of planing or gliding members 3. In the embodiment illus trated, three such members have been provided in order to secure the desired lateral and longitudinal stability, although a greater or fewer number may be used if desired for special purposes.
bers are provided they may be conveniently arranged to provide three point suspension, asillustrated, one being located at the bow in the median longitudinal plane of the boat, while the other two are located at the stern at sufficient distances from the median longi- 0 tudinal plane to give the desired lateral stadrawings, the boat com'- prises a buoyant hull 1 which forpurposes of- When three planing membility. With this arrangement each of the planin members may travel on water which is undisturbed by the action of any of the other members, and, in view of the distance between the forward planing member and 65 the propeller, the propeller may work in .relatlvely undisturbed water.
Each of the planing members is provided with a flat or slightly curved under surface terminating preferably at its forward end in a slight upcurve to cause the forward ends of the members to lift when entering waves. The total areas of the under surfaces of the planing members must be sufiicient, of course, to support the total weight of the boat on the surface of the water at normal speed. If desired, the under surfaces of the planing members may be provided with longitudinal or transverse steps, or both, in the usual manner.
Each of the planing members is preferably pivotally connected to the hull 1 on a horizontal axis transverse to the line of movement of the member with respect to the water. Thus, in the embodiment illustrated, the members 3 are pivotally connected at 4 to the rods 5 which extend through the sleeves 6 which are rigidly mounted in the boat. The sleeves preferably lie in vertical planes parallel to the longitudinal axis of so the boat,'but are inclined with respect to transverse vertical planes, the forward sleeve being tilted rearwardly, while the after sleeves are tilted forwardly. By reason of this arrangement of the sleeves, when the rods 5 and the planing members are rotated for steering purposes, the planing members are caused to bank or change their angle with respect to the surface of the water'as illustrated in Figure 6. As a result, steering control is improved because skidding is considerably lessened in making a turn.
Steering control may also be improved, if desired, by the provision of longitudinal vertical fins 7. These fins are also useful to prevent leeway as they perform the same function as the keel of a sailing vessel.
The position of the pivotal connection between each of the planing members and the rods 5 depends on the characteristics of the no sition when at member and the kind of performance desired, and may be predetermined by calculation, or adjusted by test and experiment. In general, it is necessary that the center of lift of the entire planing surface be forward of the point of pivotal connection. Thus, so long as the entire planing surface is submerged and the boat is under way there is a constant tendency for the forward end of the paning member to tilt upwardly. But, as explained hereinafter, Whenever the forward end of the planing member lifts out of the water, due to the decrease in wetted surface, the center of lift may shift rearwardly temporarily even to a point slightly aft of the point of pivotal connection, thus causing the planing member to tilt downwardly until sufiicient surface is wetted to return the center of lift to a point forward of or substantially at the point of pivotal connection.
Preferably the position of the pivoted connection is so located with respect to the center of lift that when the boat is running at normal speed with normal 'load the planing surface will assume the most eflicient angle to the surface of the water.
When the boat is at rest, it is desirable that the planing members tilt upwardly as illustrated in Figure l, in order that when the boat gets under way the planing surfaces may be in proper position to exert alift. For this purpose the center of gravity of each planing member when immersed in water may perferably be located aft of the point of pivotal connection. If the planing member does not naturally assume the proper porest and immersed in water, the rear end may be weighted, or additional means such as a spring may be provided to depress the rear end of the member.
Means may also be provided to limit the pivotal movement of the planing members in a vertical plane. Thus in-the embodiment illustrated, each of the planing members is provided with a chain 8 to limit pivotal movement in one direction and a chain 9 to limit pivotal movement in the other direction. As will be understood, the chains 8 are useful under conditions where, due to irregularities of the water surface or to other causes, the
center of lift of a member might shift temporarily to a point aft of the pivotal connection. The chains 9 are chiefly useful to prevent the members from' striking the bottom of the hull, and to prevent the members from assuming too steep an angle in starting.
For steering purposes the after planing members may be provided with tiller members 11, which said members may be connected by a cross bar 12, which in turn may be connected to the tiller 13 which operates the rudder 14 or other steering mechanism of the boat. Thus, as illustrated in Figure 4, when the tiller 13 is moved for steering purposes, the two after planing members turn .tended speed. As the with the tiller and rudder of the boat. The forward planin member may also be provided with a tifier member 11' to which is connected a rope or other means 15 for holding the planing member in fixed position. The ends of the rope 15 may be secured conveniently to a cleat on the bottom of the boat. As illustrated in Figure 5, however, the ends of the rope 15 may be secured to the tiller 13, if desired, in order that the forward planing member may be turned with the after planing members, although in an opposite direction for reasons which will be understood. 7
When at rest, the boat floats in the water in the position illustrated in Figure 1, the necessary buoyancy being provided b the hull 1, although as will be understood uoyancy might also be provided by ontoons or in any other desired fashion. ue to the fact that the center of gravity of the planing members is aft of the point of pivotal con nection to the rods 5, the planing members assume an upwardly tilted position as illustrated in Figure 1, the extent of the tilting being limited by the chains 9.
s soon as the motor is started to cause the boat to move through the water, the planing members begin to exert an lip-thrust, which, as the boat gathers speed, rapidly 1ncreases and eventually lifts the hull 1 completely out of the water, so that the boat is supported by planing action rather than by buoyancy.
As the hull rises as the boat gathers speed, the planing surfaces continue for a time to be tilted upwardly as far as permitted by the chains 9 due to the fact that the centerof lift is forward of the point of pivotal connection to the rods 5. As the boat gathers still more speed, however, the front ends of the planing members gradually lift out of water, causing the normal center of lift to shift rearwardly,
thus causing the planin members to flatten out somewhat. Thus, t e planing members automatically adjust themselves to a position depending upon the speed at which the boat is driven and the load members gradually approaching a position parallel to the surface of the water as illustrated in Figure 3 as the boat attains its inboat slows down, the reverse operation takes place, the planing members gradually tilting to theposition illustrated in Figure 2 and the hull settling gradually toward the surface of the water. As will be understood, with any given load and any given area of planing surface, the distance of the center of lift from the point of pivotal connection determines the speed at which the planing members assume their most efficient planing angle.
In steering the boat, the tiller 13 is moved to the right or left in the ordinary manner,
causing the after planing member 3 to also carried thereby, the
ICS
move to the right or left as illustrated in Figure 4, or as illustrated in Fi re 5 also causing the forward planing mem er to. turn to the left or right. Due to the fact that the sleeves 6 are inclined somewhat, as the planing members are turned for steering purposes, their angle of inclination with respect to the surface of the water is changed, or, in common parlance, they are caused to bank. In this manner, the tendency to skid in makin a turn is reduced, this tendency also being members separately pivoted thereon, and
re uced somewhat by the vertical fins 7 I It will be obmrved that when the boat is traveling at constant speed the area of wetted surface remains substantially constant even surface irregularities of the waterv thou h may he encountered. For this reason the ac tion of the boat in rough water is relatively smooth as compared with that of step hydroplanes. for example, in which the area of viding a planing surfacepivotally mounted,
wetted surface may var widely.
