Obvious answer is 'Very Carefully' but it's doable. You have to be aware of the balanced boat throughout the proceedure.. many hands will make it much easier. More hands make is safer! Just make sure they are big hands!
My son went through this process with his 20' boat. move the boat and trailer to where you want it on the stands. jack up the back of the trailer and put in the first pair of stands near the stern. lower the trailer so some weight is now on the stern stands. jackup the front of the trailer and put in another pair of stands just behind the front crossbeam, lower the trailer so the weight is now on the 4 stands. (make sure the stands are secure and strapped together across beneath the boat.) now move the trailer fwd as far as possible without hitting the front stands. place the 2 middle stands astern of the front pair and take the weight on them. Now move the front pair astern of the middle pair.
Keep shifting the boat weight on the stands till the trailer is pulled from beneath. When my son did this, he was working in a space about 18" wider than the boat!
It's a good game! Do all of us a favor and take pics throughout the process
Jerry Rubin and the rest of the Chicago 7 tried to levitate the pentagon as a Viet Nam war protest, didn't work. Buy hey maybe a Catalina 25 is doable and now that he is dead, (he died j-walking), he ought to be better at it.
Sorry, pretty obtuse reference. but non-sequitors are my specialty.
Stands go even with the bulkheads 2x2 the one with a v fitting on the bow and I put the 6th on the flat part of the keel about 1 foot forward ofthe rudder. If you are on Gravel or grass, put down some 1 inch by 1'x1' square pieces of plywood under the legs of the stands. Chain each pair to its mate and to the stand forward or aft of it so that you have a box with a triangle on either end.
Getting your boat off the trailer on onto the stands is obviously the hard part. My first question would be why?
Beyond that, I doubt your forklift can handle 6000lbs. If it can you might be able to rig something up. I would suggest you get one of the boat mover flat beds with the crane on it and have them do the job.
Next question would be How are you going to get it off the stands once it is there?
One other note, especially for heavier boats with lead keels. A substantial portion of the total weight of the boat (perhaps 80 percent) SHOULD be on the keel (via one of more large blocks of wood inserted under it). On the trailer, my 250's wing keel (and most of the weight) is resting on a trailer support.
This would make the job a lot more difficult. A couple of heavy jacks could do it, but you've got to lift the boat safely. I'd be scared of punching a hole through the side of the hull, or deforming it. You could possibly build 2 curved support beams (shape like the bottom part of the hull) and then jacking them from both sides.
The stands are mostly for keeping it from falling over. If you can get this done, remember to chain them together. It's also safer to position the stands on the hull where bulkheads are located.
Duane, I may not even us the stands. My hope was to get it high enough to get the better part of the keel. If this photo works you will see I really don't need the stands. I got the boat onto 1' 4x6 sections on top of the trailer already by picking up alternate ends with the forklift. It is not big enough to lift the entire boat. Here's the photo. I apologize for the size of the photo.
I would have to fabricate some lower pads to protect the floor as you wrote and weld on a place to chain them together to prevent movement. These were in a Gulfside marina and didn't need chains in the dirt. The more I consider the chance of something going wrong versus what I now have, I think I'll finish the bottom on the trailer.
Just had a thought! How about putting small tyre innertubes between the bunk and the boat and lifting it using them as air bags! Would it work for those of us that don't keep a fork lift in our back yard?
(I did a search for small commercial lifting air bags -- wow! nearly $3,000 for a pack of 3. Ok they can lift over 20tons!)
