First time boat owner
 

Pretty easy. Simple version. Lower trailer jack, put jacks or blocks on the back. Raise trailer jack. Then raise the front of boat off of the trailer with a jack.

I'm lucky, I have a tree growing behind my side driveway, So I put landscape timbers (6 x 6) under the keel with some 2 x 4's on the ends in the back, tie a rope to the tree and the transom eyebolts and slowly pull the trailer out until I can put more timbers under the front after the trailer has passed that spot, then I just pull the trailer out the rest of the way. I like using the timbers cause they are big, massive things that will not shift on me. This way I can work on the trailer without the boat being in the way. As a safety rule, (and I know that some here will probably disagree with me) I NEVER go under a boat that is on blocks. It only takes one mistake to have the thing fall on you and crush you to death. If I'm painting a hull I use a roller on a ceiling stick to reach under the hull. For all other things I wait till it's back on the trailer, then I'll crawl under. If a crossmember is in the way I just shift the boat forward or backward as necessary on the trailer.
