> The lifting system requires 2 12'-4x4s, 3 8'-4x4s, 2 8'-2x6s, a 20' tow 
> chain w/hooks (2-ton test), 1 chain coupler (or bolt) , 5 10"-1/2" carriage 
> bolt/nut/washer, 4 5"-1/2" carriage bolt/nut/washer, 1 2-ton and 1 1-ton 
> "come along" winches. The entire assembly can be purchased from Home Depot 
> for about $200. Basically, the 2 12' 4x4 are assembled into an "A", bolted 
> through by a 10" bolt at the top and placed around the front of the trailer, 
> over the bow pulpit. A cut length of the chain is looped around the top of 
> the "A", at the vertex, connected to the 2-T winch to the bow lift eye 
> (protect the bow and rub rail from damage.) The 8' 4x4s are assembled into 
> a "Pi shape" with cross bracing using the 2x6 materials. The ends of the 
> tow chain are hooked into the stern lift eyes and attached to the cross 
> piece of the "Pi." To lift the stern, I lower the front of the trailer to 
> the ground and shorten the stern chains to just connect. Then, when I jack 
> up the front of the trailer, the stern "lifts" off the trailer. Next, I 
> lift the bow with the come along and presto she is off the trailer. The 
> second come along is to stabilize the stern "Pi frame" so that the lifting 
> frame does not shift forward, since the frames are erected slightly tilted 
> towards the boat.
