Boat support stands / trailer transfer

[abl1111]

I want to be able to transfer my 23' Tsunami w/ an i/o to and from boat stands and my trailer.

I despise the bottle jack process; set/pump/lift/move trailer back/jack down/move jack/pump/move trailer back/lift...

It's a deterent for me from doing it.

What I want to do:

I want to be able to have my boat on a trailer, place two boat stands under either side of the stern, a bottle jack in the middle - all ready to lift the stern.

then, and here's the part I want a definitive answer for ( if there is one ), I want to put a 10' or so 6x6, or something that can take the weight, in the front part of the boat, w/ each end of the 6x6 on bottle jacks that are sitting on top of cinder blocks, and lift the bow of the boat up and off the trailer.

Then, like a gentleman - roll the damn trailer out from under the boat...

My trailer tires are 8' apart...

What say you ?
