I have a '82 wk/tr #3002 sitting on a Performance brand trailer with regular carpet covered wooden bunks. When trying to paint the bottom this covers a lot of area that can't be properly prepared and painted. Soooo, I was thinking of alternatives to the bunks. Has anyone here converted a bunk type trailer to using rollers or screw pads? The more I see of the screwpad design, the better I like it. It seems you could screw one pad at a time down to scrape and paint and then pit it back in place until all the hull is painted. Any thoughts on this?

If I had a choice I go with rollers as they allow you to winch the boat forward on the trailer after it is on level ground (when conditions don't allow you to winch the bow into the v-block when retrieving.)
I don't know how much mositure is retained by the pads which could, I suppose, be absorbed into the gelcoat possibly contributing blisters.

Having replaced all of my rollers recently I am intimately familiar with the costs. If you were to change to rollers it will cost $500-$600 and that is a conservative estimate. I have 64 rollers and the replacements from TrailRite were $13.50 each, Champion trailers had the yellow jellys for $12 each and I found some black ones that are .5" larger in diameter at Eastern Marine for $4.75 each. The mounting rails will coast a lot as well. Go to Champion and Western and see. If boats can live years on boat yard stands then they must be ok. 4 house jacks from Home Depot and some 3/4, heck do they make 1", plywood and you are done. My boat yard doesn't even put carpet on theirs. If you have not come accross my trailer project thread then here is the site from the thread.

The trailer for my C-22 had bunks, and when I painted the bottom, I jacked up the entire boat and trailer, putting concrete blocks under the four corners of the frame. Then I built a simple wooden cradle under it, situating the supports in a different place than where the bunks touched the boat's bottom. Then I lowered the trailer out from under the boat, painted the area covered by the trailer bunks, and then jacked up the trailer under the boat, dismantled the wooden cradle, and lowered the boat and trailer to the ground. It sounds like a lot of effort, but it only took about an hour each way, to jack it up and lower it, and a little over an hour to construct the cradle.

Steve, I have the bunks on my trailer too. They are adjustable vertically so, when painting is needed, I support the bow and stern with jacks, lower the bunk boards, paint, and reset the bunks.This can be done completely supporting the boat and lowering both bunks at the smae time, or supporting one side at a time. The only problem I have is getting the bottom of my wing sanded and painted.

Here is the system I use for my C-25 sk. I made a set of auxilary screw pad supports that I bolt to the trailer to do bottom/keel work. One set forward and the other under the center of the cockpit. I then support the trailer frame with four auto axle stands to stabilize it, and then start jacking the boat off of the trailer little by little, following it up by unscrewing the supports. I can get the boat about 9" off of the trailer. It works pretty good, and takes me about 1 hour to get things assembled and the boat fully up. Allows dropping the keel out, which I have done several times to work on it.

Great idea, I am going to do that.

With my EZ-Loader roller trailer I can lift (it tilts forward) the forward set of aft rollers with a bottle jack positioned on each side under the roller support tubing.

Coupled with a padded (nad makeshift) wooden 'cradle' that goes just forward of the keel and a bottle jack to lift it, the boat is very easy to raise for painting. Took about half an hour. Once lifted, it was easy to remove the rollers not involved in the lift to get easy access to the keel pivot area & etc.

After I set it down, I used the jacks under the aft end of the aft roller tube to raise the stern so I could finish the patches occupied by the other stern rollers.

I can PM some pictures if anyone is interested.
