1 Claim.
This invention relates to new and useful improvements in boats and more particularly those especially constructed for speed.
The principal object of the present invention is to provide a boat having a special pontoon bottom construction designed to cause elevation The side pontoons 9, each has an inclined outside wall 0 and an undercut inside' wall b.
The pontoon 8 serves as a balancing factor for the pontoons 9, Hi, the boat having a-tendency to rise from the water, carrying with it the pontoon 8 as the full weight of the boat is carried of the boat proper above the surface of the water when traveling at high speed.
Another important object of the invention is to provide a special boat bottom construction which will permit the boat to bank when making turns.
Other objects and advantages of the invention will become apparent to the readerof the following description.
In the drawing:
Figure 1 is a side elevational view.
Figure 2 is a bottom plan view.
Figure 3 is a rear elevational view.
Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 denotes a hull having a raisedwall 6 at its top extending from amidship to the stern and defining the cockpit area of the boat.
Numeral I denotes the boat bottom which is flat and depending from which are pontoons 8. 9 and Ill. The pontoon 8 has a, flat bottom a and downwardly tapering side walls b, the forward portion of the pontoon tapering to a point 9 merging with the pointed bow of the hull 5. The rear end of the pontoon 8 tapers to more of a blunt point i 0.
by the two side pontoons 9, In at high speed. As speed is diminished, the boat will again come to rest on the entire contacting surfaces of all three pontoons.
The purpose of having the pontoons 9, l0 provided with undercut side walls b' i to cause the boat to bank when making turns, inasmuch as a pressure will be built up against the-pontoon at the inside of the turn which will have a tendency to pull this side of the boat down while the other pontoon will skim the surface- While the foregoing specification sets'forth the invention in specific terms, it is to be understood that numerous changes in the shape; size and materials may be resorted to withoutzdeparting from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is. claimed as new is: V
A boat comprising a hull including a bottom, side pontoons on the bottom and a forward pontoon on the bottom, the side pontoons being undercut at their inner sides to permit banking of the hull when turning.
