Ok, This is the set up. Boats in the back yard, Its a wing keel, Its on the trailer,
It's a Catalina 250. I need to paint under the pads.

Now after reading all that,

"IF YOU have lowered the pads, and YOU have painted under them, Help me out.
If YOU have not done this, please PASS, I really don't need
Some one trying to get me into trouble, telling me how to do something they have never done, the boats to big and heavy to screw this up".

Now, Im now trying to be a bad guy here, I'm just looking for some good Imfo.

Dave, #411

I waited until the travelllift picked up the boat from the trailer and they waited while I threw on the paint.

John's method is probably best. I haven't painted under my pads on my 250 WK, and I'm not gonna either. It was far too harrowing soda blasting under them. I lowered the pads & jacked up the boat. You never get the pads back to the original height, I eventually had to go float the boat on a local lake to get them back on my original grease pencil marks. The keel support had started sagging from the weight and I was worried about damaging the trailer, or worse the boat.

I have no intention of ever doing it again this way. Next time it'll be done in a yard where I can call over the travel lift to do the work without worrying myself about damaging the boat, trailer, or me.

I documented a lot of this on the forum, including pictures, search for "soda blast" and my name.

If you want to give me a buzz to talk about it, my number is four two five eight nine one one nine four five.

The last time I painted our C-25, I intended to get under the pads but could not find boat stands short enough (I have a swing keel boat and a fin keel trailer) in the time I had available. So I didn't paint under the pads. I watched the guy who did my bottom job, on his 6-pad trailer, when I bought the boat. Mark the pad positions before you move anything so you'll know the settings to restore. He lowered the 2 center pads, one at a time, painted, and put it back up, telling me that the other 5 pads would support the boat sufficiently. For the 2 pads on the bow end, he placed a boat stand under the bow and on the sides as close as possible to pads to be lowered, chained them together, and lowered one pad at a time, painted under the pads, let them dry, and put plastic wrap over the pads before raising them back up. Same procedure for the stern pads, but used only 2 stands as close to the end of the trailer as possible.
If your trailer has bunks, your only option might be to build supports under the boat, inside the trailer, using blocks of wood and carpet scraps, deflate your tires to lower the trailer enough to paint the areas covered by the bunks and re-inflate the tires after the paint has dried. I have not ever done this, just my thoughts.
I would also keep handy a pair of 2-ton bottle jacks, and 4x4's to make cross beam supports, etc. for added support and to be able to restore the pad settings. With care, planning, and common sense, you should be able do this safely.

We never paint under the pads. On our lake I don't think its worth the hassle.

I have bunk boards rather than pads so the problem is compounded. Basically you need to beg, borrow, steal, or buy a jack stand to place next to each pad, brace the boat, lower the pad enough to paint under it, then reset the pad. Obviously you don't want to do this on grass unless you can keep the jack stand from sinking into the ground, causing the boat to sag. You also need to ensure the stand is secure from moving out from under the boat when weight is place upon it.

In my case, I have to brace the boat fore and aft, usually with blocks, drop both bunks, then sand and paint. My boat has been done twice in this fasion, once with ablative paint at the dealers, and once completely stripped and repainted with VC-17 by a professional. I will be renewing the VC-17 next season tho I am undecided if I will do it myself or not.

I paint under the pads and keel every year ..

i use 4 jacks , jack up the trailer , block the boat then lower the trailer .
This is a lot of weight and a big repiar bill or worse if it it falls ..

Sean, I like your approach but I'm curious. Do you paint under the pads first, then do the rest of the hull after getting the boat back on the trailer?

this year i scuffed the boat , then lifted it , scuffed under the pads ,
dusted off with a broom and painted .
so i painted under the pads first or the whole boat except where its blocked first .

i use a fan to dry under the keel so i could drop it down the next day ..

I have never painted the bottom of by boat on a trailer, but I have scrape it in the water while it stood vertical on the wing keel. I would wait for high tide and then drive the boat to shore until it stopped. Then tied the bow to a tree on shore, main halyard to the dock on the port side and jib halyard to starboard to the anchor. I then would wait for the tide to go out which left six inches of the keel under water. I then scrape the bottom and polished the sides while the boat stood vertical on the keel with no problem.
I think you could do the same using the halyard tied to a tree or solid place and lower your pad on the opposite side, paint it, let dry then reverse the process for the other. I got the idea for my scraping work from a picture Catalina use to have in their advertising which showed a 30 footer standing vertical on the wing while the tide was out. They even had some guy standing under the boat to show the relationship.
