ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to watercraft. More specifically, the invention relates to powered surfboards.
2. Description of the Related Art
Personal watercraft have given much pleasure to people who enjoy recreation and sports on navigable bodies of water. It has only been recent in the history of personal watercraft that motorized personal watercraft have made great strides in providing pleasure at a reasonable cost. These motorized personal watercrafts, the most common of which are wave runners and jet skis, have several disadvantages to their design. First, wave runners and jet skis are operated in a fashion such that they do not assimilate surfing, either wave surfing or wind surfing. This prevents the user of either of these watercrafts from working or using body balance as a primary source of direction. Essentially, the users of these craft steer the water jet propelling stream of water to move in a desired direction. Second, the weight of these watercraft are extreme. Typically, such watercraft require at least two people to move the watercraft when out of the water and require trailers for transport and/or launch. This restricts the use of these watercraft to only being used when two people are present to put the watercraft into and out of the water. U.S. Pat. No. 5,582,529, issued to Montgomery on Dec. 10, 1996, discloses a personal watercraft. This watercraft is singular in construction in that there are no secondary structures extending out from a primary structure. A deck is used by the operator to lay on or stand on as is desired by the operator. An internal combustion engine is housed in the center of this watercraft fore of the deck upon which the operator is positioned. Output and exhaust fumes are transmitted out of the internal combustion engine toward the stern of the watercraft. While this design more approximates surfing, it is not an optimal design. First, the internal combustion engine is housed in front of the deck for the operator and prevents the operator from guiding the watercraft with agility due to the displaced center of gravity of the watercraft and the operator to a position in front of the operator. While sharp edges protruding from the bottom of the hull (183A, 183B) were introduced into this watercraft to overcome this displaced center of gravity, these edges do little to overcome the displaced center of gravity to the position in front of the operator. Second, the watercraft is of a weight which requires at least two people to move the watercraft to and from the water. As stated above, this is a disadvantage especially in light of the fact that this watercraft is designed only to have a single operator on the deck thereof.
SUMMARY OF THE INVENTION AND ADVANTAGES
A watercraft for movement in water includes a board having a stem and a stern. An interior compartment is defined therebetween. A longitudinal axis extends through the board between the stem and the stern. The watercraft includes an internal combustion engine. The internal combustion engine is housed within the interior compartment of the board. The internal combustion engine generates an output force and exhaust fumes as a result of its consumption of fuel. The watercraft includes a pump which is connected to the internal combustion engine. The pump receives the force from the internal combustion engine to force a portion of the water therethrough. The watercraft includes an exhaust assembly which extends out from the internal combustion engine fore of the internal combustion engine toward the stem of the board.
One advantage associated with the invention includes the ability to operate a watercraft similar to that of a wave surfing watercraft or a wind surfing watercraft. Another advantage associated with the invention is the ability to generate a force to move the watercraft absent waves and/or wind. Still another advantage associated with the invention is a watercraft of reduced weight such that a single person may move the watercraft into and out of water. Yet another advantage associated with the invention is a watercraft having a center of gravity substantially in line with the center of gravity of the operator of the watercraft as the operator operates the watercraft.
