Jacked boat off trailer

[Solace of Freedom]

I thought I'd share w/ y'all how I lifted my C22 off the trailer. I don't have access to a com-along in a barn, friend w/ an earth mover or anything like that. And, I did not want to build an extensive structure to lift it or slide it on to. I only needed to seal and paint under the bunks so I jacked it up using cinder-blocks, 4x4s, the old bunks that I replaced on the trailer last yr, a floor jack and a bottle-jack. I positioned the floor-jack on cinder-blocks in the rear and the bottle-jack towards the front w/ the 4x4's on those, then the old bunks under the hull. Its' been up for over a week, because the weather's been too bad for me to start w/ the barrier coat. I did wedge some blocks on the trailer bunks for protection when we had the gusty winds last week. And, I've got carpet burns on the backs of my hands from sanding above the trailer bunks. I was able to access about 1/2 the length of the keel top and keel trunk w/ it lifted about 1&1/2" off of the trailer. I just need about 3 dry days in a row to wrap it up.

I think that anyone who has ever jacked their boat off the trailer has come up with different ways and techniques of doing it. There are guys who jack the trailers up and shore under the boat and then lower the trailer down. One of my friends uses his sailboat stands, blocks under the stern, and the farm backhoe to hold the bow long enough to get the trailer out from under his O'Day 25. It can be a dangerous task no matter which way you choose to do it.
I've been using my four sailboat stands under the stern of my boat, a powerboat stand under the bow, a hydraulic floor jack, and many 6x6x3.3' and 4x4 blocks to raise my O'Day 222 off my tandem bunk trailer. The hardest part of the task is getting the trailer out from under the boat. It would be a whole lot easier to have a gantry of some kind to support the bow while the the rest of the hull is suspended up over the trailer enough for the trailer to clear the hull.
I just ran across a youtube of the company in my area that manufactured my sailboat stands. They manufacture such a device that anyone with metal fabrication skill could probably build.
I've discovered a little trick that can be done in getting the trailer positioned back in the right place in order to get the keel centered on the trailer's keel board, and it's very simple. I place a short wide plank under the center of the trailer's cross member and place the jack on the board so that the trailer can be shifted to either side to get that 1 or 2 inches needed by using the jack's iron wheels for the trailer to slide sideways.
I use a block&tackle from a tree or anything stationery to pull the trailer over. I've also used a 10' iron digging bar to push it over.
The ground near my house has pea stone and it slopes off a little. Hence the need for a plank to set the jack on. Also, I had to jack up one side of the trailer and shore up under the wheels in order to get the trailer level for lowering the boat on it. Here's a youtube, compliments of Brownell's Boatyard.

I usually jack(12 ton pneumatic makes it criminally easy) the whole trailer and boat up, block the stern, temporarily strap the bow to the shop roof, pull out the trailer, block the bow, paint/cuss/drink like a sailor for mental health reasons, reverse procedure.

If I didn't have a stout roof I'd just lift the whole trailer and boat until satisfied, block bow and stern, remove the trailer wheels, lower the trailer hubs to pads, drape sheets over my trailer, work around it and then paint/cuss/drink like a sailor to dilute toxic dust/fumes and mask pain.

The beauty of our small boats is found in a fairly quick bottom paint job, usually at our house, on our schedule.

Be safe, Mike

Soling, I second your method. I did it on my H26 and SJ23. I didn't have your roof strength so I used a cross beam front and rear.
