What size beams are those? 6x6 or 8x8's ?

6x6 if anyone in Fla. needs to use the steel holders they are just sitting in the shop but you will have to get new 6x6 as I used them on a landscape project.

I have two more screwjacks and if I can't get the Yardarms from the boatyard I have to raise the boat with the screwjacks, back the trailer under the boat until it's against the forward jacks, place the two spares, remove the ones against the trailer, back up a foot and repeat the process until the boat is under the trailer. After you've done it a few times it's not a bad job. Yardarms make it a ten-minute job though.

FloridianSon,
How much does your boat weigh?

Crazyhorse,
I like the jacks, have seen them for aircraft but not boats. Were is a good place online to order them?

prater, check with greg at offshore extreme, in moore was okc but moved to moore, I know he was getting set up in his shop again to do this, you can also check with Robin at superior fibergl*** in okc as well if he would rent you some or lift it there since it is winter time now.

They're around $100 apiece and you can probably find them at boater's world or West Marine, places like that.

Anyone doing what Florida son made I would suggest a notch in the upright beam to carry the load. You are relying on the beam not to crack were you bolt it the way it is done in the pictures. If you make a shoulder it would be much stronger.

Crazy I paid a guy to come over with a tow truck to lift up my bow and then drove under

Yeah, the guys at the storage facility have heavy equipment and offered to do that. I have easy access to a set of Yardarms so it's not a big deal. I like to be sure I'm lifting the boat at the bulkheads rather than from the eyehook.

I've pulled a boat off a trailer before like CrazyHorse said. (29 Sundancer) Used jackstands like those pictured and went to Home Depot and bought cheap beat up 6 x 6's that I cut up into 18 inch pieces for the keel blocks. I've also had a BIG tow truck lift and entire 29 Chapparral and back a trailer under it. (It had been on blocks)
You can order the stands from Brownell (sp) direct. They were less than $100.00 with freight.
