Filed Sept. 25, 1929 Shoots- 5210 2 yaw/217' BY my WITNESS: ATTORNEY T WW i t -1,776-,3 1 9 "oAsIMIn- AeDrTs, or 'En'mc NEW you]! if This.inventionrelates toimprovementsin boats and hasespecial relation to hulls, an

object being to provide .a boat hull which WlllOfi QI'fHJ minimumamount of resistance to the action of the water. so that the "hull will remain practically upon an evenkeel atall times, while thejcharacter of. the hull V will increase thespeedof the boat for a given amount of power. 1

HVVith the above and other'objectsin view,-

' the invention further includes the following novelfeatures and detailsof construction, to

a be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in; the appended claims.

In the drawings 7 Figure 1 is an elevation partly away showing the boat hull constructed in accordance with the invention. I

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, theboat, as shown at 10 I in Figure 2 of the drawings, is pointedat both ends so as to decrease water resistance at'the forward end of the boat and reduce drag at therear end.

, ,The' hull is provided witha'keel 11 which is substantially V shaped in cross section and Q hull, The sides which-extends throughout the length of the of theikeel 11 are inwardly curved as indicated at 12 and merge into outwardly curved bulbous'portions 13. By reference to Figures8, 5 and 6 of the drawings itwill be seen that ull upon opposite sides of its transverse center provides a compound curve of sections which meet at the point ofthe keel and which extend outwardly and downwardly around thebulbous portions 13; The bottom of the keel is spaced slightly below the lowest point of the bottom of the hull and the bottom provides longitudinally I disposed depresy sions or channels for the passage of water beneath the I hull while the character of the bulbous portions resists side motionflof the to the glancing effect brokenthroughout the length the bottom of the the keel, an outwardly ppposite sides of said hull curve inwardly from the bulbous portions 'as shown at 14. Outwardly curved overhanging portions 15 extend from these inwardly curved portions with the outwardly 14 and the 'latter together curvedioverhanging portions 14 act to deflect' heavy seas upwardly and outwardly so seas will be broken due that the force of the produced by the shape of the hull. curved portions 14;

of the hull so that the pointed ends 10 also provide similarly shaped portions as shown in Figure 1. The

shape of the pointed ends of the hull further acts to reduce water resistance during the forward movement of the hull and to reduce drag at the stern.

From the foregoing description and accompanying drawings it will be seen that the invention provides a boat hull used for boats of various sizes and character from the smallest boat to the largest seagoing vessel. The character of the hull is such asto decrease water resistance when and to cause heavy seas to glance off the hull so that the latter will not receive the full im pact of these seas. the hull in heavy seasso that the boat will remain upon an even keel in severest weather The inwardly and outwardly and 15 also extend a the boat is under way 1 i omen sums PATENT; omen f i This will act. to stabilize and the comfort and safety of the passengers will thus be assured.

The invention is susceptible of various changesin its form,v proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is 1. Ina boat, a hull having a substantially V-shaped keel whose side walls merge into the bottom of the hull on opposite sides of and downwardly disposed bulbous portion extending from-each side of the keel, upwardly and inwardly j g Y, 1,776,319
