LCAC or Air Cushion Vehicle landing gear

VERY general question and I hope someone can guilde me on this.

I am scratchbuilding a Ma.K air cushion vehicle that to my knowledge has never existed in that universe so I have no guidlines.  On modern air cushion vehicles there is no external landing gear visible so it must be inside the skirt.  Does anyone know what tpe of arrangement ACV's use when they come to rest either aboard ship or land. 

I have looked all over the internet and come up with only a couple of cutaway drawings that did not help, and literally thousands of photos of them doing what they do best.

thanks!
