Cable-stayed bridge replace older bridges all lowered the relative price of these designs. Cable-stayed bridges date back to 1595, where designs were found in "Machinae Novae", a book by Venetian inventor Fausto Veranzio. Many early suspension bridges were cable-stayed construction, including the 1817 footbridge Dryburgh Abbey Bridge, James Dredge's patented Victoria Bridge, Bath (1836), and the later Albert Bridge (1872) and Brooklyn Bridge (1883). Their designers found that the combination of technologies created a stiffer bridge. John A. Roebling took particular advantage of this to limit deformations due to railway loads in the Niagara Falls Suspension Bridge. The earliest known surviving example
Pontoon (boat) to meet unexpected demand. Weeres, later called "Mr. Pontoon", was elected to the Minnesota Marina Hall of Fame. Pontoon (boat) A pontoon boat is a flattish boat that relies on pontoons to float. These pontoons (also called "tubes") contain a lot of reserve buoyancy and allow designers to create massive deck plans fitted with all sorts of accommodations, such as expansive lounge areas, stand-up bars, and sun pads. Better tube design has also allowed builders to put ever-increasing amounts of horsepower on the stern. Pontoon boat drafts may be as shallow as eight inches, which reduces risk of running aground
