Wanting to do some work on my trailer, just wondering if anyone has any experience or ideas for getting he boat off the trailer? Like putting it up on blocks? How do you get the trailer out from underneath? Thanks in advance!!!
For smaller boats only. Please use extreme caution. Use tools, not your hands. Choose a safe area to work. chock the trailer wheels.
Use hydraulic jacks, heavy-duty jack stands to back up the jacks, plywood pads, shims and stacked, 4X4 criss-cross blocking with 2X4 cross ties (nailed).

1) Jack the transom at the keel, clear of the trailer bunks or rollers. Support it with stands and block with 4X4 timbers at both corners and the keel.
2) Now place jacks and second set of stands inside trailer framing, well ahead of the axle(s). Jack at the keel, just high enough to get the hull clear of the trailer. Block it up at the keel, then remove the forward stands. Pull the trailer forward until the axle reaches the blocking.
3) Now block behind the axle(s) at the keel and at the chines for balance. Remove the temporary forward blocking. Repeat the process (2) until the trailer is clear.
4) Reverse the process to get the trailer back under the boat. The winch may help.
This is always done on level ground. When completed, the keel and corners at the transom and the keel and chines around midships is blocked and also the keel toward the bow. Always try to keep the most weight on the blocking at the keel and the weight evenly distributed. Blocking and/or stands at the chines and transom corners is for balance.
