this is how i did mine this morning with 3 guys ( four would be better ). i could of driven 45 minutes each way to Piru with two trucks and pay 20 bucks to get in and gas but i'm to cheap!
*DISCLAIMER* THIS COULD BE HARMFUL TO YOU OR YOUR BOAT!!!!!!
MUST BE DONE ON A FLAT CONCRETE OR DRIVEWAY.NOT IN THE STREET.
(DO AS I SAY NOT AS I DO)
ok now thats out of the way.
REAR LIFT POINT - trailer picture 1
attach engine hoist to motor. ensure that when you lift the hull it is level left to right. make sure your stringers are in good shape!
FRONT HULL LIFT POINT trailer picture 2
floor jack. position a the V part of the hull. use something to protect your hull from the floor jack,( i used a rubber volley ball ) you will have to reposition the floor jack as you pull the trailer out.
trailer picture 3
the HULL is off of the trailer and steady
trailer picture 4
the jack repositioned and pulling the trailer out from under the hull as you pull the trailer out ,you can only go a foot or so because of cross members. jack the hull up pull the trailer out let the jack down and repeat. i had to reposition about four times.
once the trailer is free of the hull ( if i had a fourth guy he could of taken more pictures

) this is the most dangerous time so be careful!!
now you can support the hull with a dolly or a different trailer.( DO NOT LEAVE THE HULL SUSPENDED BY THE HOIST AND FLOOR JACK ALONE!!)
trailer picture 5 is the end result.
AGAIN BE CAREFUL!!
