f fi vENToR ATTORNEY UNITED STATES PATE JULIUS C. CHRISTIAN SEN, OF NEW YORK, N. Y.
MARIN E VESSEL.
To aZZ whom it'may concern:
Be it known that I, JULI-Us C. CHRISTIAN- smv, a citizen of Germany, and a resident of the cityof' New York, in the county of New York and State of New York, have invented certain new and useful Improvements. in Marine Vessels, of which the following is a specification.
The present invention relates to improvements in marine-vessels, and the invention resides. more particularly in the hull structure of small craft, such as motor boats, sail boats and small yachts.
One of the objects of the invention is to produce. a fiat bottomed hull, having simple means for diminishing the resistance between the water and the vessel, when mov ing through the, water, and effective in increasing the sp ed.
Another object. of the invention is to produce a normally open boat having a collapsible cabin, or top, that can be conveniently and quickly set up, when needed.
A. further object of the invention is to utilize the otherwise unused stern part of the hull by locating therein awater tank, for holding fish, etc., if the vessel is used as a fishing boat.
A further object of the invention is to provide a marine-vessel, that is capable of being used as an ice-boat or sleigh.
With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction with-in the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.
Two of the many possible embodiments of the inventionare illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a boat hull constructed in accordance with the present invention; Fig. 2 is a top plan view of the same; Fig. 3 is a front elevation thereof; Fig. 4 is a rear elevation of the same; Fig. 5 is a section taken on line 5-5 of Fig. 1; Fig. 6 is a side elevation of the vessel, partly in section, showing the cabin Specification of Letters Patent.

or top in its extended position; Fig. 7 is a side elevation of a modified hull construction; and Fig. 8 is a top plan view of the hull shown in Fig. 7.
Referring now first to Figs. 1 to 6, inclusive, of the drawings, the numeral 10 indicates the hull of a small craft, including a bottom 11 that is fiat from the sternpost 12 forward to a transverse vertical plane 13, at which the midship body of the vessel joins the bow part 14 thereof. From this plane forward the bottom rises toward the stem 15, it being slightly, curved both longitudinally and transversely. The longitudinal edges of the bottom converge from the plane 13 toward the stem 15,'and also from the said plane toward the sternpost 12. The stem 15 is inclined forward and is connected by a keel 16 with tl1e.stern post 12, the said keel projecting below the surface of the bottom from the plane 13 approximately to the stern-post. The sides 17 of the hull rise substantially vertically throughout the length of the vessel, so that transverse cross-sections of the same from the stern-post to the plane 13 are of substantially rectangular configuration. From the plane 13 forward the bases of the crosssections are slightly curved, but are otherwise substantially of rectangular configuration. The curved portion of the bottom joins the stem 15 in a plane that is substantially in the water line of the vessel.
From the foregoing it appears that the largest transverse cross-section of the vessel is disposed in the plane 13, that is to say 1n a transverse vertical plane in which the' bow part of the vessel joints the midship body thereof, the said midship body de creasing in width gradually toward the stern part of the hull, and the said'stern part terminating in a vertical post. In other words, the stern part, in horizontal cross-section, is in the form of an inverted wedge, the point of which is constituted by the post 12.
The construction of the transverse frames 18 of the vessel need not be described herein. as the same does not form part of the present invention. These frames are, in the construction shown in Figs. 1 to 6, inclusive, of the drawings, disposed in vertical planes, as usual in constructions of this type.
The vessel is of the open boat type, it being provided, if necessary, in its bow part with a deck 19 and in its stern part with a deck 20. Between these decks is disposed the cock-pit.
Immediately in rear of the deck 19, there is mounted upon one of the transverse frames 18 a partition-like board 21, the said board being rotatable on trunnions 22, that are mounted in the said frame substantially in the plane of the deck 19. This board is normally disposed within the hull, as shown in Fig. 5 of the drawings, partitioning off the bow part 1 1 from the midship body, whereby a bunkand storage-room 19 is obtained. In front of the after deck 20 is mounted, upon the adjacent frame 18, a
transverse stringer 23, upon which is adapt ed to be placed a standard 24, rising from the said stringer, as shown in Fig. 6 of the drawings, and adapted to be secured thereto in any suitable manner. The board 21 is adapted to be extended above the deck 19 vertically, and on the said board and standard 24: is placed, in the longitudinal center line of the vessel, a spar 25, for instance the mast ofthe vessel, if the latter is of the sailing vessel type. A fabric piece 25, such-as a tarpaulin or a sail is then placed over the said spar and secured to the free edges 26 of the board 21 and to the sides of the hull all along the cock-pit, whereby a top is provided for the said cock-pit, when required.
When there is no use for the top, the fabric.
p Below the deck 20 is placed a, preferably,
By reason of the fact that the largest transverse cross-section of the midship body of the hull is disposed in a vertical trans verse plane, in which it joins the bow part of the vessel, the resistance between the water and vessel, when moving through the water, is greatly decreased,with the result that its speed is increased. The slightly curved portion of the vessel bottom constian inclined plane,,which has a tendtutes to raise the boat out of the water and ency to diminish the amount of submerged surface, that would oppose resistance to speed movement through the water.
A modification of trated in Figs. 7 and 8 of the drawings,
differing from the one above described in that the stern post 12 extends at an acute angle to the keel, it being inclined forward 7 he invention is illus,
and connecting the midship body of the hull with the said keel. The stern body 28 of this hull constitutes thus a true wedge, decreasing even to a greater degree the resistance between the water and the vessel. Otherwise the construction is the same as of thecraft above described, with the exception that the after deck 20 is in this case missing.
In the hull, shown in Figs. 7 and 8 of the drawings, the transverse frames 18fare disposed in planes substantially parallel to the stern post 12. 'The purpose'of this arrangement is to increase the resistance of these frames to stresses to which theyare subjected in the line of motion by the wa-' are two auxiliary keels 16 mounted upon the flat portion of the bottom 11, one on each side of the keel 16. These auxiliary keels constitute runners, on which the boat slides when used as an ice-boat or sleigh. This construction may also be applied to the boat shown in Figs. 7 and 8.
It will be understood that the boats here in described may be propelled by sails',.m"otors or oars, and may beused as pleasure boats, fishing-boats,house-boats, etc.
Attention is also called to the fact that, While herein the boats have been described as belonging to the small craft type,-the general hull construction described may be made use of in building marine vessels of any desired size.
