Abstract: A personal watercraft comprising: a) a generally vertical outer hull; b) a bottom member affixed to the lower edge of said outer hull and closing the watercraft from the encroachment of surrounding water into the vessel; c) a generally concave inner hull rigidly attached at its upper edge to the upper edge of said outer hull and extending downwardly toward said bottom; and d) a generally horizontal deck fixedly attached at its edges to the lower edge of said inner hull to form an enclosed space with said outer hull, inner hull, and bottom member; said deck having a size sufficient for the support of at least one person in a standing or reclining position and of sufficient cient strength and support to avoid undue bending from the weight of the user.
