Re: From Ground to Trailer with a 20' Boat?
if the boat is sitting completely on the ground, like the trailer up straight with the boat, and start winching. you will need a couple of guys to help. if it is on blocks, again line it up and start working the trailer under it.
this would be the preferred way.
Getting Boat Off Trailer
you don't need stands.
1/you can lower the tongue to the ground. i would get some 6x6 or old railroad crossties cut the +- 12 inches, now block up the transom. 2/
Raise the tongue of the trailer the back of trailer will drop away from trailer. this is the tricky part. between the cross braces of the trailer block the keel lower trailer, boat will be suspended on the blocks.
3/ pull forward, lift bow again, and reblock i a different place. repeat until trailer is out from under the boat.
4/ to reload, just reverse the procedure.
if you were just working on the bunks, or painting the bottom. you could just do the first 2 steps.
