This invention relates to boats and has for its principal object to provide a boat having a hull design that permits of high speed operation of the boat in rough water or high seas without danger ofbeing capsized.
Still. other objects of this invention reside in specific details of construction and combination of parts, as will hereinafter be fully described' In accomplishing these and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein- Fig. l is a top, or plan view of a boat embodied by the presentinvention.

, Explanatory to the present invention, it will here be stated that it is my intention that this boat be of a kind that may be equipped with steering and propulsion means capable of various means of remote control; that is, to be equipped with known devices that adapt it to be operated as above explained, under control of apparatus, also known in the art, that maybe located on the ship, aircraft or land station from which the present boats are to be controlled, so that the boat, after being loaded with explosives or other materials, may be directed to the object to be destroyed. I
Furthermore, it is anticipated that these boats be of a character to be equipped with sound sensitive devices, capable of being tuned to receive certain sound vibrations whereby to effect the steering control devices in such manner as to cause the boat to seek the particular object to be destroyed. For example, such, an object might be a submarine, or battleship. As alternative means for this purposadevices based on the thermocouple principle may be used, these to be set to pick up and follow heat rays as from the smoke stack of a vessel, or infra-red rays with the object of finding the vessel or other object through fog or smoke screen.
It is also the intent thatthe presentboat be designed to be equipped with devices, also capable of remote control, for causing its cargo of explosive materials to be set off, or exploded at any predetermined instant, or to be reset against explosion in the event that it should bev desired to cause the boat to return to its-launching station. Especially, it is desired to so design the present type of boat that it can be caused to safely ride the waves at high speed, without capsizing and without being thrown ofi course.
Furthermore, his the intent that boats of the character above outlined shall be of a kind adapted to be made from non-strategic materials which are readily available, such as plywood panels, and that they may be powered by engines of various kinds or types; for example, automobile engines, motor boat engines, or by engines of special design for this particular purpose.
Referring more'in detail to the drawings- The hull of the boat, as observed best in Figs. 1 and 2, is of substantial beam and relatively shallow. The opposite sidewalls Ill-l0 of the hull are substantially vertical throughout the length of the boat, being gradually curved inwardly toward each other to form the bow end, as noted at II in Fig. 1. From the curve of the bow section, the side walls Iii-40 extend substantially parallel. to each other to somewhat beyond amidships and :then, beginning at the point I z in Fig. 1, a slight inclination toward each other to the stern.
The stem panel [3 is substantially square cut, having but slight rearward curve, and is inclined rearwardly to slight extent from the bottom.
An important feature of the design of the present' boat resides in the novel bottom construction. It is to be observed, in Figs. 2 to 5, that slightly forward of amidship, the bottom is stepped, thus providing a vertical, transverse and rearwardlyfacing shoulder l5. Forward of this shoulder, the bottom has a longitudinal keel ridge it from which the opposite side sections l1 and ll of the bottomslope upwardly in a lateral direc tion, as shown best in Fig. 4, and merge into the bow at about the load water line. It is noted in Fi 2 that the water line, or base line is desi nated at W and that the stepped portion of the bottom is somewhat below this line, while the bottom, where it meetsthe stem, is just above the Water line. The bottom sections iI-il meet the "thus-prevented I horizontal line, as shown at in Figs. 3 and 4.-
and then .as itron-tinues rear weirdly, lie transverselyicurved, as notediin Figs. :3 and 6; so that in effect the boat will have three concentrated areas or points of support when traveling at high speed in the water; one area being along the forward end portion of the keel, of the bow section, and the other twotareas .beingalong the rear end portions of the oppositep-side areas at the bottom of the stern section. This stem end;
support of the boat is augmented by pontoons 'o'r wings 26 and 26 that are built onto the opposite side walls along the stem end portion of the hull,
' as=shown in Fig.1. These poiitoons'haveaoutside1 Walls '21 Which are "subStal'itiaMy I upright, and
have bottoms 28 "that s'lo'pe invwardly and downwardly at an angle of'about-45to meet the edge off the bottom 1 section 22 'thus forml-n *kejel 1 ridges -'[t is shown inFig. 6 "that these pontoons or wings 1 extend laterally of the bull -to substantial distances, and "are closed, thus "to give additional buoyancy and' g'r'eater insurance against capsiz= 7 ing the boat in high speed-operation.

Water that may enter the hood through opening $3 will be drained off through openings sGB in theeopposite side walls of the hood. Opening-fidasinrFig. .12, is preferably equipped with a hinged valve plate 69 to permit outflow but to check'infiow of water. V
.Inzorder that any water that might for any reason enter the boat hull may be drained oil, Ihave' provided "a scupper tube 10 opening ---at its forward end through the-'bulkhead ffl into the cockpit as shown in'Fig. 5.

It will be readily understood that in -travel of the boat there will be anatural-suctionproduced that willkeep'the hull drainedof anfy water that "might leak thereihto. 7
For the propulsion of the boat, i'have provi'ded This may be any'suitable type, and it maybe located and supported as "shown in Fig. 5 or in any other suitable or desirable position. As here shown, the engine shaft extends forwardly through the bulkhead 30 and is operatively connected by 'gearingdesignated at 91 with the'propeller-shaft 9-2; 'Shaft92 "extends through the step portion of the bottomfithrough a suitable bearing 33 'andfatits "rear jend lis T031- ried by .a bracket {i l tand is "there equipped with propeller'95.-

However, the .tiller niight be operated mechanically by mechanical devices .lunder magnetic control and timed by block mechanisms of various kind. The ,prime mover .and steering controldevices, per se, are not @claimed as. parts of this invention exceptas elementsof -.a-comblnation. Y
The design of this boat provides ample space for the .loadingof explosive vor/and incenliiiary material such as used for the destruction of ships, docks .and installations. Such .materials may beplaced in thehold-of ithe Iorwardmortion .of the boat as well asinithe cockpit. :Space is;also;providedfor.the carrying ofiaztankloffuel operations and the exploding of the explosive material.
Boats of this character of construction may be operated at high speed in high seas and rough water with safety to equipment and will not capsize. Therefore, they are especially suited to the intended use as weapons of destruction. However, when modified to some extent, they are suitable for peacetime uses. Therefore, I have shown in Figs. 8 and 9, a modification of the boat structure especially for peace-time uses. In these views it is to be noted that the cockpit is open and about it a housing H0 is built, providing an open cockpit. The ventilating hood 60 of the boat previously described, is embodied in this structure which extends to the stem to house the tiller lever to which the conventional steering cables or other devices might be attached. This housing provides a streamlining effect that is especially desirable for speed boats. be understood however that this is but one of various modifications in the hull design of the boat shown in Figs. 1 and 2.
Such boats as here have been described are extremely desirable for the purposes stated and in their construction and use, the objects of the verse, vertical, rearwardly facing step, and there being lateral pontoons built onto the'hull at opposite sides along its aft portion; that part of the bottom that is forward of the said step being It is to formed with a central, longitudinal keel ridge that merges into a tapered stem, and with that part that is aft of the said step being transversely arched to the full width of the bottom and downwardly and rearwardly sloped, with the aft side edges of the bottom joining with the bottoms of the pontoons to form each with a keel ridge.
2. A boat as recited in claim 1, wherein the bottoms of the pontoons merge gradually into opposite sides of the boat hull and wherein the keel ridge of the forward portion of the bottom and keel ridges of the two pontoons are downwardly sloped in a rearward direction.
3. A boat of the character described comprising a hull having substantially vertical sides, a transom type stern panel, and a bottom that is formed at approximately amidships with a transverse, rearwardly facing step, and having that part of the bottom that is forward of the step formed with a central longitudinal keel ridge leading into a tapered stem, and with the opposite side sections thereof upwardly and laterally sloped to merge with the sides in chines that are inclined upwardly, forwardly and lead into the stem along upwardly curved lines, and having that part of the bottom that is aft of the step transversely arched to the full width of the bottom and downwardly and rearwardly sloped; lateral pontoons built onto the hull at opposite sides along its aft portion; the aft edges of the bottom joining the bottoms of the pontoons at opposite sides of the hull to form longitudinal keel ridges and the bottoms of the pontoons 85 merging gradually into the sides of the boat hull.
