Problems solved by technology

While the diameter of the pontoons could be increased, this would also increase the overall height of the pontoon boat which would change the shipping characteristics, as well as raise the center of gravity, further reducing stability.

first embodiment

[0018]With respect to FIGS. 1-3, pontoon boat will be described. Pontoon boat 2 is generally defined by a frame 4 having a plurality of pontoons 6 attached to an underside thereof, and having a deck 8 attached to the opposite side thereof. Railing 10 surrounds the deck portion and encloses an interior area 12 which includes furniture 14 and the captain's area 16, including a seat and console. It should be understood that the pontoon boat could also include other amenities such as a changing room, for example as shown in our U.S. Pat. No. 6,681,713; or could include a bimini top as shown in our U.S. Pat. Nos. 6,820,569, or 7,107,926; all of which are incorporated herein by reference.

[0019]With respect now to FIG. 3, the pontoon assembly 6 is comprised of two outer pontoons 20 and an inner pontoon 22. The outer pontoons 20 are substantially cylindrical in cross section and are attached to frame 4 by way of brackets at 24. Center pontoon 22 is a substantially closed volume of curviline...

second embodiment

[0022]With respect now to FIG. 4, pontoon boat is shown at 32 having framing 34 and a deck 38. Rather than three pontoons, two outer pontoons 40 could be provided attached to the framing 34 by way of brackets 46, where both pontoons are elliptical in cross-section. Each of the outer pontoons 40 is of elliptical configuration where its minor axis and major axis could be of any dimension. Elliptical pontoons 40 could also include fins 48 to also assist in turning of the pontoon boat.

[0023]With reference now to FIG. 5-7, alternate cross sections of pontoons are depicted which could also be used with the present disclosure. FIG. 5 shows an oblong or obround configuration 50 have straight sections 52 and arcuate sections 54, having radii 56. FIG. 6 shows an oval shape 60 having multiple radii, such as 62 and 64. Finally, tube 70 could include a flat or low profile triangular portion 72 connected by arcuate sections 74 having radii 76. These and other curvilinear configurations are contem...

Abstract

A pontoon boat is shown which includes a frame, and a plurality of pontoons attached to the frame. The plurality of pontoons comprises two outer pontoons of substantially cylindrical configuration and a center pontoon comprising a substantially curvilinear configuration, wherein a height of the center pontoon is substantially equal to the diameter of the outer pontoons. One embodiment of the pontoon is elliptical in cross section.

Description

FIELD OF THE INVENTION[0001]This application relates to watercraft, and in particular to watercraft having pontoons for flotation.BACKGROUND OF THE INVENTION[0002]It is common in the watercraft industry to provide a plurality of pontoons on watercraft for flotation. This type of watercraft is typically referred to as a pontoon boat and the pontoons are generally comprised of longitudinal tubular members having a closed cylindrical cross-section. A frame is constructed above the pontoons and the pontoons may have brackets which connect the pontoons to the frame. Above the frame is a deck to which furniture and seating is arranged for the pontoon boat passengers. These types of pontoons may include outboard engines, as depicted in our U.S. Pat. No. 6,939,184, the entirety of which is incorporated herein by reference; or may have an inboard engine as depicted in our U.S. Pat. No. 6,681,713.[0003]It may also be desirable to have a third pontoon, which is typically centrally mounted in a...
