Re: Need advice on trailer repair
If it is a roller trailer it would be very easy. If it is a bunk trailer, it could be a more difficult.
If it is a roller trailer, Back up to a tree, loosen the bow strap so you have about a foot of slack pust the boat back, if it does not go, back the trailer up and lightly tap the brakes, you want to get the end of the boat hang free. keep doing this until the boat is balanced on the back of the trailer. Have someone stand on the tounge of the trailer to raise the back end of the boat, then block the back of the trailer. Cinder blocks, and 2x6 work well. Run a strap around the tree, to the boat. Block the keel and slowly pull the trailer forward and add blocking to the keel as you move forward.
To get the boat back on the trailer, you will have to winch the trailer under the boat, just like pulling the boat at the ramp, but this time you back the trailer under the boat lift the tounge high, and get the trailer back as far as you can, attach the trailer winch and crank it the trailer should slide under the boat.
