SUBJECT: # 19668: How to paint bottom of boat while on trailer.
Submitted by Jim/Wi (4.4.9.44) from WISCONSIN on 4/5/2001 1:02:00 AM
I'm getting ready to paint my alumiun 18 ft boat but it's on a trailer. Some time ago I remember reading a post about how to do it by lifting the boat by the bow eye but can't remember the details.
Anybody have any hints for me. Thanks. Jim/Wi

Capt. Steve Moore (64.205.83.178) from MASSACHUSETTS says Did it last weekend
Here's how I did my Parker last weekend. I used a 4,000 lb floor jack and put it on the front supports of the trailer just in front of the bow. I used a small piece of soft pine that I wrapped in a towel and placed on the front of the keel and lifted the bow off the trailer. That allowed me to get the bottom except where the aft rollers were. After I was done with the front and middle of the boat, I re-connected the winch strap and chain and moved the floor jack to the stern. I needed more lumber on the lack to reach the keel at the stern because the jack was now on the floor, but I basically used the same technique to do the aft portion of the bottom.Just make sure everything is stable before you go under the boat. Hope this helps.

Ds (63.91.35.162) from MASSACHUSETTS says Roller trailer?
If you have a roller trailer you can back the boat up on the trailer 6-12", paint everything, then slide it forward and paint the holidays. I bought a very small (.5" or so diameter) roller at Home Depot to reach some of the tight spots.

Jim, I have found that it is easy to lower the trailer all the way down and then block up both sides of the boat in the rear. Then raise the jack as high as possible, and block the front. Then lower the jack and the boat should be off the trailer. Good luck.

Local Motion (172.183.229.140) from NEW YORK says I wouldn't bother....
When I trailered I always painted around the rollers, never had any growth in these hard water areas.Now I paint around the blocks that my present boat sits on. Same thing....zero growth in hard water areas.
Without the presence of growth in these areas, I feel it is a waste of time to mess around with moving the boat and/or playing with jacks, turning a 1 hour job into 2 or more.

Rageboat (152.163.204.77) from PENNSYLVANIA says easy painting
I used to lift my boat with hoists to paint, but what a pain and very time consuming. DS got the right idea with a roller type trailer. An 18 ft. alum. boat should be very lightweight. I have learned a much simpler way since.Back the boat trailer up against a tree. Tie off the stern of the boat to the tree from both stern eyes and then pull the trailer out from under the boat approx. a foot or so. Paint that area directly around the rollers and winch the boat back on. With a roller type trailer this is easily a one man job. If it is a bunk type trailer, you may have to wet the bunks or spray them with silicone to get the boat to slide back into place. Should not be a problem though.

Jim/Wi (4.4.9.1) from WISCONSIN says Taking trailer out.
Thanks guys. Although I was planning on painting the boat on the trailer,I like the idea of taking the trailer out, especial since my trailer needs painting also. So I like Seatractors idea of first lowering the front down , placing blocks under the back by transom and then raising the trailer up. Then, what would be wrong with could using the bow eye to winch the boat up off the trailer. This seems like it would be easier to get at the bottom and do the work with out the trailer in the way. I have gang planks for walking out that would really make it hard to get to one side of the hull. Any down side on blocking the transom and them using the bow eye to raise and hang the boat?jim/Wi

With two 20' boats and one trailer, I do this a lot, just like seatractor said. But instead of blocking the stern up with two sets of cribbing, I built a 2x6 framed wall with bunk carpeting on top that is just the right height to slip under the stern when the trailer tongue jack is cranked all the way down. I sheathed the wall (one side) with plywood so it wouldn't rack, and built small a-frames on each end of the wall so it couldn't tip forward or backward. For the front I got a 10' 4x6 beam and put screw-type house jacks under each end spaced so that the trailer will roll out.shoes

Thanks, guys. After considering all methods I decided to do the blocking method on transom. I have a lot of cinder blocks laying about so I used those for the transom. I attached a rope though bow eye and attached it to a winch to a beam in my garage with extra bracing. Gave it a test yeaterday and everything sould work just fine. I started striping the paint from the sides of the boat while srill on the trailer and will remove the trailer when I'm ready to do the bottom. Thanks again for the tips.
