Re: getting the boat off the trailer
how do you get a 5000lb boat off a bunk trailer???
The easy answer is to put the boat in the water.
On land, here's a suggestion:
Lower the trailer tongue as far as possible. This will raise the stern of the boat. While the stern is raised, block up the transom with suitable support. After blocking up the transom, raise the trailer tongu as far as possible; this will lower the stern end of the trailer leaving the transom on the blocks (off the trailer). Now block up the bow. After the bow is blocked, lower the trailer and the boat is off the trailer.
Of course your trailer is still trapped under the boat. You can pull the trailer as far forward as possible, until a trailer crossbeam hits the blocks supporting the bow. Then raise the trailer to lift the bow enough to unweight the bow blocks and replace them behind the trailer crossbeam. You may need to do this a few times to completely free the trailer. Once you get to the axle, raising and lowering won't help since you're at the pivot point. The bow is relatively light (compared to the stern) so you should be able to use an automotive jack or similar to lift the bow.
Be absolutely sure the boat is safely supported. Use this advice at your own risk.
