Abstract: A boat pontoon has a V-shaped keel region and a frame on deck connected to points along the keel region by rods of adjustable effective length. Any limited part of the keel region can be deflected in one direction by increasing the length of the rod connecting the frame to that part of the keel region and in the opposite direction by reducing the length of that rod.

Abstract: A method is provided of avoiding or minimizing inflammation at a painful freshly burned epidermal skin site, which comprises applying on the skin site promptly before the appearance of overt inflammation, an anti-inflammatory composition in homogeneous non-alcoholic aqueous solution form consisting essentially of distilled hamamelis water, magnesium sulfate, and copper sulfate to allow for transdermal absorption of the composition at the skin site for a period sufficient to achieve local relief of inflammatory symptoms.
