Please guys can you help me in this dilemma. Would like to clean, scrub and paint under the 4 roller arms( 6 rollers each arm) while boat sits on the trailer. Could you please explain me how i should do it? Was trying today to put blocks under portside chine to remove one roller arm at a time. As soon as i disengaged roller arm, boat tilted a bit to the side where i removed the roller arm and luckily was supported with stands, but lost the height in order to put back the roller arm and had to jack the boat slowly in order to gain the roller height again to reinstall, fearing for my safety or doing damage to boat and make a catastrophe. Honestly i was afraid. As im new to boating would like your views explained in detail on a possible way to remove arm , do the job, reinstall arm and moving for the other arm or an easier way to do the job.
Your help is greatly appreciated.
 
Why don't you leave the rollers, and just edge the boat back a bit on them to allow you to paint the bits normally covered by the rollers?

How should i do it exactly? i am afraid that because all weight is at back when i move boat back will fall or tilt back . i know im asking silly questions but i cant figure it out. still under shock from todays experience. thanks mate.
 
Most trailer boats don't use antifoul, so it's not a common problem. As you say, it's tricky to move the boat far enough forward and back on the trailer. You could drive the trailer to a dry stack if there's one near you, and pay the guys to lift the boat with the forklift while you paint the bits you've missed. I'd guess they'd charge you about £50, maybe less for cash in hand.
 
Put scaffold tube/timber joist under the trailer frame perpendicular to the length then use 4 or more large ratchet straps from the boat to the braces . This should hold the boat in place while you lower one at a time . Obviously your straps must be individually attached to a strong point i.e. Cleat, and not just looped round the hull. Use the truck straps, about 50 mm wide not the Mickey Mouse halford type. They don't stretch so you don't have to be over zealeous with the tension.
Carefully carefully now!
 
Tie back of boat to tree or similar solid object with trailer hitched to car. Drive forward a few inches so you can paint the bits you want. Then winch boat back into place.
Or, use jack to prop the hull at the outermost chine adjacent to the rollers you want to drop. Do one at a time.
Both methods have worked for me!
 
I've taken my boat off the trailer 3 times whilst on land. It's not very big though only 19' with a V6 stern drive but all the weight is at the back.
Consequently I would go with rafiki's suggestion and in answer to your concern about her tipping up, there is a very simple solution and hopefully this will work for you.
You will need to be able to brace her with straps on the rear eyes to something like a post or something solid, I used the tie down straps in order to pull the trailer forward. Next measure the height from the keel at the transom to the ground and find a large block of wood or blocks strong enough to support the hull at the rear, but see if you can get something a cm or so higher, in a similar way in which a boatyard will use for storage.
The next bit is a little tricky but if you put a jack under the draw bar, lift and then lift the jockey wheel and lower the jack to the ground, if you have the right amount of weight set for the hitch, it will lower. The stern will then lift enough for you to push in the block or blocks. When you lift the draw bar and set the jockey wheel the stern should be braced by the block.
Attach the stern braces and attach the winch strap to a post. Then gently wind the trailer forward just enough to reveal the areas you wish to paint.
Good luck.
ps whilst I was writing war and peace I see DPB posted a more simplistic version. Lol!
But it does work.
