  • Device for attaching pontoon forms of watercraft to rigid keel forms
    Patent number: 5875730
    Abstract: A device for attaching pontoon forms of watercraft to rigid keels. The invention utilizes an elongate member attached to the keel. The elongate member includes an arcuate form having a surface that substantially conforms a portion of the surface of the pontoon. The elongate member also includes a channel which receives a lip extending radially from the pontoon. The interference between the channel and the lip prevent the pontoon from being radially removed from the elongate member. The surface of the arcuate form may include ridges.
