    • The boat or craft disclosed includes two spaced parallel hulls that are connected together by a platform extending between the hulls. The platform and the two hulls form the top and sides of an air space beneath the boat with the hulls supporting the platform above the water. Curtains of flexible material are spaced longitudinally in the air space and extend downwardly from the platform and transversely between the hulls to close the forward and rearward ends of the air space, whereby the pressure in the air space can be maintained above ambient to provide an air cushion to support a portion of the gross weight of the boat. The hulls are designed to provide a buoyant force due to displacement that will support 100% of the design gross weight of the boat when there is no pressure in the air space and the boat is not moving or is moving at a relatively slow speed through the water. The hulls are also designed to provide hydrodynamic forces that will support the boat when the boat is moving at a relatively fast speed with no pressure in the air space and will provide hydrodynamic forces that will support between 25% and 40% of the gross design weight of the boat when the pressure in the air space is at design pressure and the boat is moving at a relatively fast speed.
    • 公开的船或船包括两个间隔开的平行船体,其通过在船体之间延伸的平台连接在一起。 平台和两个船体形成船下方空气空间的顶部和侧面,船体支撑水面上方的平台。 柔性材料的帘幕在空气空间中纵向间隔开并从平台向下延伸并且横向地在船体之间封闭空气空间的前端和后端,由此空气空间中的压力可以保持在高于环境温度以提供空气 垫子以支撑船的总重量的一部分。 船体设计用于提供由于位移而产生的浮力,当空气中没有压力并且船没有移动或以相对较慢的速度移动时,该位移将支持船的设计总重量的100% 水。 船体还设计用于提供流体动力,当艇在空气中没有压力的情况下以相对较快的速度移动时将支撑船,并且将提供将支撑总设计重量的25%至40%的流体动力 当空气中的压力处于设计压力时,船只以相对较快的速度移动。
