THis gadget is so useful for stepping the mast I lost mine and now hate putting my mast up. The EZ step should consist of a small stainless peice and two pins ( partially threaded bolts that fit can be used when you loose the pins-they tend to dissapear). There should be marking on it (14,16 and an up arrow). The smaller side of the peice (part tappered in more) goes in between the gap at the mast step on the fron cross bar with one pin through it to hold it in place. The larger tappered out bit should be sticking out, and be able to rotate to some degree. It's tappered out to stop rotating when it comes against the step as you rotate it upwards. The mast base (which also has a small hole) slides in between the larger tappered out bit, and slot a pin through the correct hole. This is a bit of effort, and someone would generally hold the mast extended out the back of the boat while you get the pin in. Once booth pins are in, you can hop onto the tramp and hoist the mast as the other person walks around to secure the forestay. To get it out, you'll have to push the mast up as far as you can and let the other person take it out. Don't forget it in. If its too tight, it will be easier to get out once the jib is tightned. Hope this makes sense..
