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.

(Kansas City). It is well-established that the poor eat more junk food overall than the more affluent, but the reasons for this are not clear. Few studies have focused on variations in food perception according to socio-economic status (SES); some studies that have differentiated based on SES suggest that the economically challenged don't perceive healthy food much differently than any other segment of the population.
