Referring tothe drawings and to the preinvention selected I. have shown in hull 11 of the inferred embodiments of my for illustrative purposes, Fig. 1 a boat having verted V-bottom type, resents inverted V roadening' aft and preferably in a substantially straight stern transom,.
2 and 3 and showing the rudders when steering the bottom of which sections gradually terminating as illustrated in .Fig. 4, the construction being generally v United States .November 7, 1916.
similar to that shown in my Patent No. 1,204,355, issued A portion of the boat amidships is broken away. Forward" of amidships of the boat, I have shown rudder posts 12, 13 carrying vertically disposed rudders 14, 15, as, best shown in rudder posts passing the boat at points substantially from the keel 16 and v tance from the chines 17, 18.
I i as suitable flexible driving arrang fied by thecable 22 passing over unison by a ement typithe sheaves turn on the water, and
- is travelling at great speed.
by the 23 and 2 1 and wound around a drum 25= on the steeringpost of the boat.
The before-described rudder mechanism constitutes a preferred type of how steering means. Bow steering means cooperating with a boat having a hull of the inverted V-bottom type is particularly etiicient, because, as the rudders are turned to guide the boat in the desired direction, the rudder on the inside of the turn will always tend to pull down that side of the boat on the inside of the turn, while the rudder on that side of they boat adjacent the outside of the turn will bank the water against the bottom.
of the boat and tend to raise the adjacent side of the boat, thus efl'ectively banking the boat for the turn, precluding the tripping of the side of the boat on the outside of the banking that portion of the bottom of the boatadjacent the inside of the turn so that it presents an oblique surface to the water, which tends to oppose skidding without producing any tendency to trip. At the same time, when the boat is turning at great speed, an opportunity is afforded whereby the boat may swing or pivot on that portion of its keel adjacent the bow steering means, thus promoting quick turning without danger evenwhen the boat In Fig. 3, I have shown a modification of how steering means wherein the rudders 30, 31 are inclined inwardly, being shown substantially perpendicular tothe adjacent hottoms of the boat, this inclination of the rudders increasing the banking action of the boat when "turning arising from pulling down that side thereof at the inside of the turn and elevating the side of .the boat ad-- jacent the outsideof the turn; the rudder on theinside of the turn will undercut the water and the opposite side of the boat will overcut or tend to plane on the water. Where the rudders are thus angled relative to one another, I may provide rudder controlling means typified by the rack 32 en-' gaged by the pinion 33, which is connected to the steering wheel of the boat, the move ment of the rack 32- being communicated to the-rudders through connecting links. 34, 35 providing suitable ball or other universal connections so that there will be no binding arising from the absence. of alignment between the rudder pivots.
- While the bow steering means is of advani 7 ing or semi-planing type regardless of the a type of propulsion used therewith, such steering means is particularly useful in connection with surface propulsion systems wherein the propeller, hubs are at or slight,
1y above the level of the water presentedfrom beneath the adjacent bottom of the boat. 'I have shown in the present application surface propulsionmeans including a single propeller 40 having its hub 41 slightly abovethe-bottom of the stern of the boat 42. To oppose lateral movement of the stern of the boat,-tending to move the stern of the boat in the direction opposite to that f in which the propeller blades move through the water, I have provided adjacent-the propeller immersed plates 43 and 44. herein shownas extending forwardly and rearof the propeller and opposing latera movement of the stern actuated by 'paddling'operation of the propeller: Thus,
if the propeller illustrated is turning in clockwise direction, as viewed in Fig.- 4, the pressure on the inside of the plate 44 will be reduced while the pressure on the inside of the plate 43 will be increased, thereby causing pressure of the water on the outside of 'the plate 44 and on the inside of the plate 43 to overbalance the opposed pressure on the opposite sides of said plates and urging the stern of the boat to port, as viewed in Fig.-
dercut the side of the boat, while cut the water, tending to raise the starboard precluding tripping of 4, counteracting the paddling-tendency of the wheel 40 to urge the stern to starboard.
Where, as in the preferred form of my in-. vention illustrated,'the plates 43 and 44 are angled relative to one another so that their general planes will meet below the bottom of t e boat, not onl5 is lateral paddling action minimized by reason of the inclination cut ting off the flow'of water from below the plates, but steering action when turning at speed is facilitated because, when the stern of the boat starts to swing in turning atspeed, the plates 43 and 0 44 will assist in banking the boat toward the inside of the curve. Thus if theboat, as viewed in Fig. I
4, is turning to port, the plate 43 will unwater, dragging down the port the p side of the boat, thus the starboard side of the boat in the. water and contributing to the anti-skidding action of that side of the inverted .V-bottom of the boat toward the inside of the turn.
While I have shown and described preferred embodiments of my-invention, it will "side of the turn.

A ,boat of the inverted V-bottom type having bow rudder means projecting through the bottom thereof and comprising two ruders substantially equidistant from the keel and on opposite sides thereof,- said rudders connected for conjoint operation and, when turning the boat, inclined relative to the direction of movement of, the
