Help setting up trailer for 17'whaler

[cwlson]

So I just picked up this 1986 17' whaler that was flipped upside down on this trailer. I pulled the hull off the trailer now Im trying to figure out how to set the trailer up for the boat. I have never done this before(but I am fairly good at turning a wrench) at this point im not really sure what the best way to approach this is and would appreciate any guidance that I could get.

and another about Whalers http://continuouswave.com/whaler/reference/

You trailer looks like an older Calkins model
