Bottom Painting on the trailer

[mjsiega]

So how do you bottom paint your C-Dory when it's on trailer, more specifically how do you get to the spots where the boat is resting on the bunks? I imagine if you have rollers, you can simply pull the boat back off the trailer a foot or so, but how do you do it with bunks? Thanks.

There are some threads here about that. HERE is one of them.

Lower the tongue, block the back of the boat. Raise the tongue as high as you can, then block the bow. If you are living right, you might have just enough room to get in there when you lower the tongue a bit... if not, then you can lower the bunks on the trailer.

The monohulls are slightly easier to paint than the cats. I always used a set of jacks, with a steel plate between the jack and at least a 2" x 6" x 1 foot block--one on each side aft, and one in the center foreward. Then you can either walk the boat off the trailer, or just raise it enough to put 4 x 4 blocks between the bunks and the trailer. I personally prefer to use cribbing of blocks, rather than concrete blocks or jack stands, once working on the boat. if you are under the boat, double the supports! Don't take chances.

I would use the jack stands that you see in the boat yards. I did try to sand a Bayliner 2855 while it was on the trailer. It is very hard to get into the the areas that are blocked by the trailer parts. I had to have it lifted off and placed on blocks. While it was on blocks I had it soda blasted. That was a Big Mistake. The Person didnot know how to do the job. I was left With A 28 ft boat bottom full of blisters. He took all the barrier paint off and opened all the blisters. I had to fill all the blisters after work in 40 degrees, Then sand and put two barier coats on by truck head lights. I had the yard put bottom paint back on. I was very greatfull to the yard manager for not charging me for the space and electricty I used .
