Cantilever spar cable-stayed bridge reaches toward the cable supported deck and is counterbalanced by a structural tail. In the Assut de l'Or Bridge (2008), the curved backward pylon is back-stayed to concrete counterweights. Cantilever spar cable-stayed bridge A cantilever spar cable-stayed bridge is a modern variation of the cable-stayed bridge. This design has been pioneered by the structural engineer Santiago Calatrava in 1992 with the Puente del Alamillo in Seville, Spain. In two of his designs the force distribution does not depend solely upon the cantilever action of the spar (pylon); the angle of the spar away from the bridge and the weight distribution
Pontoon (boat) equipped with motor mount, battery storage area, fishing rod holders, canopy, fishfinder mount, small anchor and other required fishing gear. Such boats are suitable for ponds, lakes, rivers and seas during calm weather. However, due to light weight, they are susceptible to waves and windy conditions. Nonetheless, such boats are often used even for big game fishing. Pontoon boats for pleasure boating and fishing can be low cost for their capacity, and cheaper to insure than other boats, even when equipped with substantial engines. Pontoon boats are used as small vehicle ferries to cross rivers and lakes in many parts
