Blocking

[Jimgodiving]

I want to block my AR240 off of trailer to clean the bottom. I bought 4 stands. I have blocked boats before but first time on a jet boat. Has anyone done this yet.

 

[Jimgodiving]

I am very surprised that no one out there has blocked there boat off there trailer.
I guess I will have to take some videos of me doing it on Sunday.

You're a first as far as i know! Is it that dirty down there?

I would think that @Julian or @Cobra Jet Steering LLC might have some experience/knowledge on this.

My only experience is on small sail boats that I could damn near lift up on my own - don't believe that information will apply here.

I just want to wax the whole bottom. I am using a machine to get the best results. Marine 31 products.
I take the cleaning process seriously. I spent over $300.00 to get great stands. Will send picks.

Can't wait! I would love a fresh coat of paint over my whole bottom and can paint but this is the part that is scary!

Another member turned me on to these. Kinda pricey, but sweet.

I literally hate you right now.

EDIT: I know, we don't hate. But come on...

Especially for @swatski !

Somebody did document how they lifted the boat off the trailer to do trailer maintenance. I believe he started by lowering the tongue down, supporting the rear of the boat (blocking) and then raising the tongue all the way, then blocking the front of the boat and then lowering the tongue of the trailer which left both ends of the boat supported on blocks and the bunks free from the hull. I'll try to search for the post.

It might've been @CrankyGypsy

Here's one post that might have the info. But I'm not 100% sure this is the one I was thinking about.

Here's another post where @CrankyGypsy gives instructions as to how he did it.

Hope this is what you're looking for @Jimgodiving

I looked it over. Thanks for sending in that direction. I will take some pictures so everyone can see it on a newer boat.
I am sure others would love to be able to clean there boat with out the trailer in the way.

i don't think i went into much detail anywhere about how i did that? i made two keel supports - one for below the drain plug and one up front. and yes, @itsdgm is correct, the way i did it was to drop the tongue of the trailer all the way to the ground. now place the rear-most cinder blocks on either side with a 2x4, plus the stack below the drain plug (not a lot of weight on this, though), then raise the tongue back up higher than level; support the front with the V-block (pics below) on a bottle jack; with everything in place, lower the tongue a little and the boat should come off the bunks; roll the trailer forward until the trailer cross members (and axles) get hung up by the front support; then you do the tilt trick again and move the support behind the cross members; keep leap-frogging like this.
edit(s): considering the wheels, it's very likely that i waited to the end to add the mid-body blocks shown in the third photo and just used the front V-block until i could place them. i never jacked the boat with the bottle jack, but rather used it to raise the support to the keel before tilting the trailer and transferring weight to the V-block. i did some front keel repairs and added a keelshield - so i left the front of the boat supported on the back of the rear bunks and removed the V-block to have full keel access.

i found several pics of our boats supported with two jack stands and a giant styrofoam cube under the front keel, so i was confident in trying this. it's a slow process, just be patient with it. i was careful not to put too much weight on the keel supports (the side blocks are holding most of the mass). i opted to keep the front of the boat slightly resting on the trailer bunks since i wasn't working there and needed it like this for a few weeks ...felt much safer over an extended period.

here are pics of the V-block support for the front. i also kept a folded towel between it and the keel.





this is where i got the basic scheme:

Pretty smart.
Thanks

@CrankyGypsy has the best method for serious hull work.

But a ghetto version of @Bill D system

,
for our light boats could be just few (4-6?) of those , mounted upside down,

When you say "paint" are you referring to anti-fouling paint?

Nope.
My boat spent over half its life down in Florida on a lift in the sun over brackish water. The owners also rubbed a good spot off the keel and then tried to hide it with a keelguard. I repaired the damage but the gelcoat wasn't tinted 100%
Not that anyone sees the bottom down there but it would be nice to touch up and was nice etc. The problem is that unless it matches 100% then i end up blending into a larger section....


Yeah, this is why i have left it alone!

So you want to re-gelcoat the bottom of your boat? You should be able to find the exact factory color so no blending would be necessary. If you're patching, then you should be able to bring back the original color with some wet sanding and buffing after you spray your patches.
