Pontoon effect Pontoon effect The pontoon effect refers to the tendency of a vessel whose flotation depends on lateral pontoons to capsize without warning when a lateral force is applied. The effect can be sudden and dramatic because pontoon boats usually cannot rely on the righting effect of a keel (which contains ballast). The vessel is stable and self-righting up to the point that the centre of gravity shifts past the centre of buoyancy of the ship and the vessel rapidly capsizes. The pontoon effect is theoretically possible whenever the vessel's entire weight exceeds the buoyancy of the pontoon(s) on either side.
Junk (ship) After their successful journey this junk was anchored as a tourist attraction at one end of Barcelona harbor, close to where La Rambla meets the sea. Permanently moored along with it was a reproduction of Columbus' caravel "Santa Maria" during the 1960s and part of the 1970s. In 1981, Christoph Swoboda had a 65 feet (LoA) "Bedar" built by the boatyard of Che Ali bin Ngah on Duyong island in the estuary of the Terengganu river on the East coast of Malaysia. The Bedar is one of the two types of Malay junk schooners traditionally built there. He sailed this
