this construction and arrangement the propellers may function as shown in Figure 2, or may beswung upwardly to the dotted position shown in the same figure, and still function. In addition the propellers may be swung over to rest on the rear support 40 and still permit the parts to function and power to be transmitted from motor 2 to the respective propellers so as to cause a reverse pulling action. When it is desired to move the boat a short distance to'the rear or-in a rearward direction, the clutch 9 is disconnected and the propellers swung over either when functioning or non-functioning, said movement continuing until the parts rest on, the rear support 40. When the propellers functionin this position the boat will be pulled rearwardly. Sometimes this is done when it is desired to check the forward speed of the boat as the,

propellers may be quickly swung out without disconnecting them from the motor.

;' Asshown in Figure Zthereis provided a plane 44- which is sometimes known as a fantaiLsaid plane or .fantail mounted at 45 to an enlargement 46at the bottom of the boat. A'controlling plate 49 is secured thereto. A screw member; 5|]

having a pair of stops 5! and 52 extends throughthis aperture andinto the threaded-extension 53 whereby when rotating wheel 54 the fantail 44 may be raised or lowered as desired; When the front of the boat begins toelevate as the speed increases the fantail is lowered and consequently brings the boat ona more even keel, thus securing better results in view of the fact that the boat is lifted slightly so as not to extend into the water quite as far as it did heretofore. This reduces the resistance of the water and permits, in a limited sense, a better planing action.

As shown more particularly in Figures 3 to 5, V

inclusive, there is, provided a sail structure 6 which may be used if desired, or maybe taken down and stored. away on the boat when not in use. The sail structure 6 includes a hollow mast 55 which. slips over the threaded base 41,; as shown in Figured, andv extends upwardly inthe usual manner of masts. If desired bracing guy wires or other bracing members56 and. 51 may be used to reinforce the mastwhen in use. The top of themast is providedwitha pulley wheel 58-over..which a cable 59 extends, said cable being adapted to be secure'duat any time to the post. 60 and alsoito extend over ,the pulley 6|. From post v6!! the cable extends through or over pulley 5|, pulley 58 and then'downwardly until it is connected at BZ'to the saidsheet 63. As shown in Figures 4 and 5, the sail sheet is wrapped when'not in use and is supported by the cable 59. Spars or bracing "arms B5:and 66 are pivotally mounted'on the mast 55 and may be positioned at right angles .to the mastwhen the sail is in use, as shown in Figure- 5, or may be swung to a parallel positionwhen the mast is removed and stored inthe boat. The sail at the lower end is'secured to a boom 61 which is adapted to be rotated by hand wheels 68 and S9 whenever desired, or by some special mechanism as shown in Figures 6 and -7. This mechanism consists of a'corrugatedroller 10 having a'pinion 'H secured thereto, which pinion continually meshes with the idler 12, which in turn meshes with the pinion 13.

'When the pinion 13 is rotated by the hand member 14 the train of gears just mentioned will be caused to-function and roller l0 will retate through the action of friction to lower the sail and wrap it at the same time. It will be understood that'the cable 59 is released gradually during this rolling operation. After the sail sheet has been rolled into place the sliding plate 15 is moved over to the position shown in Figure 4, unless it has previously been left in this place. After the sail has been rolled as. shown in Figure 5 and it is desired to remove the mast, the same is merely lifted upwardly until it is disconnected from the base 4|. The rolled sail 63 is then removed, plate 15 being slid out of the way during this operation. After the sail has been removed it is swung parallel to the mast and preferably lashed thereto, after which the mast, sail and associated parts are stored away. It will be understoodthat the members 65 and 66 are also swungto a parallel position with the mast before the mast is removed.

When the mast is in use the propellers 4 and 5 areswung to-the rear as shown in Figure 3 and.

in which it "is placed. It will, therefore, be seen that when the sail is not in'use it may be used either with or without the motor for propelling the'boat, and when not in use either set of propellers may be used or both propellers may be used simultaneously to propel the boat forward or rearward. When propelling the boatrear wardly it will be necessary to reverse the propeller 3 which is done usually by reversingthe engine 2.'. When the engine 2 is reversed and it is 'desird'to use both of the air propellers as well as the water propeller, the air propellers are left in the position shown in Figure 2. V

-Iclaim:- I q- 1. A boat of the character described, comprising a boatbody, a water propeller exterior of the rear of the boat body, a pair of air propellers mounted substantially centrally. of the boat body, said air propellers being mounted to swing around a horizontal axis, each of said air propellers having a driving shaft adapted to extend forwardly when in one position and rearwardly when in another position, a motor carried-by the boat body, and a plurality of means for connecting said motor with the air propollers and the water propeller,; said means being adapted to be adjusted to connect the air propellers and the water propeller at the same time to the engine and at anothertime to connect either the air propellers or the water propeller to the engine. 2. A boat of the character described, including a boat body, a pair of air propellers, a shaft for propellers may point towards the front, point upwardly and towards the rear and receive power in all these positions from said power means.

3. A boat of the character described, comprising a boat body, a water propeller carried by the boat body, an engine for driving said propeller, a pair of swingably mounted air propellers, means for transmitting power from said engine to the air propellers for causing the air propellers to rotate, a mast arranged adjacent the front of the boat body, a boom extending tansversely of the mast an equal distance on each side thereof, means for normally supporting said boom, a sail having one end secured to said boom, the upper end adapted to be moved upwardly to the top of the mast, a cable connected tothe upper end of said sail, means for guiding the cable over the top of the mast and downwardly to a point at the front of the boat body whereby said cable may be used for raising the sail at any time, and a plurality of manually actuated means for rotat- 3 ing' said boom and that partof the sail wound thereon to wind up the sail completely.

4. A boat of the character described, including a boat body, a removable mast arranged normally at the front of the boat body, a plurality of arms pivotally connected to said mast and when in one position arranged to extend transversely of the mast, a triangular shaped sail, a boom connected to the lower end of said sail, a. cable connected to the upper end of said sail, means for actuating said cable over the top of the mast and downwardly towards the front of the boat body so that when the cable is pulled to the upper part said sail is pulled upwardly and in front of said arms, said mast being rotatable, and cables connected with the ends of said boom for manual actuation whereby the mast and sail my be shifted from one position to another for facing in the right direction with respect to he wind.
