MultiThom 201 Posted September 9, 2020 Share Posted September 9, 2020 I have a pretty light boat (1000 pounds). I want to wax the bottom occasionally (sailboat-trimaran). Don't want to spend 1000 dollars on the brunnell system which I'm sure would work. I think I could do the following process pretty easily, but don't want to break the boat--so helpful tips welcome. Step chock the wheels and lower the bow all the way with trailer wheel jack-the stern lifts support the stern with stands, one on each side or a heavy duty sawhorse with a cradle built for the stern. Ensure nothing is holding the boat to the trailer except gravity using trailer wheel jack, jack the trailer up (stern should lift off the bunk) Using tall jack stands on either side (or sawhorses) and a long bar, support the bow far enough apart so trailer is removeable lower the trailer wheel jack-boat should remain supported off the trailer. I am a little concerned at step 4 that the boat may try to slide and off the stern support or the support(s) themselves might topple. If anyone has a simpler suggestion, I'd appreciate the thoughts.

Zonker 3,978 Posted September 10, 2020 Share Posted September 10, 2020 Tie boat to tree. Unstrap from trailer. Gun it. Just like removing a tablecloth with dishes on top. 1 Quote Link to post Share on other sites

See Level 948 Posted September 10, 2020 Share Posted September 10, 2020 Zonker's right, But for a novice I'd say pulling out slower and land the hulls on saw horses as its pulled off of the trailer might also work. Quote Link to post Share on other sites

knobblyoldjimbo 30 Posted September 10, 2020 Share Posted September 10, 2020 1. Park the boat on the trailer where you can pull the trailer out from under the boat. 2. Anchor the rear of the boat - tie a rope through the drain holes etc. 3. Pull the winch out and attach to back of car or tree etc. 4. Wind trailer forward, with jockey wheel low so back is high 5. Put stuff under stern. I've used tree logs and old tyres. 6. When you get to the balance point support the gunnels, I used treated pine half logs. 7. Keep winding, when you can get another log or tyres under the area just after the balance point you're done. Wind trailer out of the way. Did this several times on a 700kg Careel 18.

European Bloke 718 Posted September 10, 2020 Share Posted September 10, 2020 If you're fucking about under the boat polishing make damn sure it's well supported. A bit of polishing might be just enough to dislodge a stand. Darwin award in the making. Quote Link to post Share on other sites
seaker 32 Posted September 10, 2020 Share Posted September 10, 2020 Your idea will work fine. I have done the same with a trailer sailor so we could paint all of the bottom. And if you take the wheels off you will lower the trailer even further. Quote Link to post Share on other sites

Zonker 3,978 Posted September 10, 2020 Share Posted September 10, 2020 The barrels look sturdy but I'm not so sure about the plastic bucket supporting the rudder. Might buckle... Quote Link to post Share on other sites
Max Rockatansky 681 Posted September 10, 2020 Share Posted September 10, 2020 I wish... that bucket was fulla water I was using to polish her bottom, the orange thing is the pad I was laying on Quote Link to post Share on other sites

Dart96 38 Posted September 11, 2020 Share Posted September 11, 2020 My neighbour has a J22. To antifoul he has a wooden gantry fore and aft with a strap going under the boat. He tightens it all up then let's air out of tyres and removes the wheels. Trailer drops enough to antifoul the keel. Quote Link to post Share on other sites

Monkey Butler 104 Posted September 11, 2020 Share Posted September 11, 2020 Capri 22 hoisted off trailer solely by two $14.99 Harbor Freight ratchet straps. Easy once you find something to hang the straps from. https://www.harborfreight.com/3300-lb-capacity-2-in-x-27-ft-heavy-duty-ratcheting-tie-down-1-pk-60689.html Quote Link to post Share on other sites

That’s a pretty typical practice for bottom painting trailerable powerboats. I’ve done it probably half a dozen times. I used stacked cinder blocks ( with 2X4’s stuffed down them to hold the stack together) and then some padded 2X10’s to support the boat. Easy and safe. Edit: an appropriately sized floor jack works much better than using the trailer wheel jack. Fold that thing out of the way. Quote Link to post Share on other sites
MultiThom 201 Posted September 21, 2020 Author Share Posted September 21, 2020 Well, I decided to get screw jacks anyway....but not the boat stands from brunnell--which I've owned in the past and are very good; but overkill for this small boat. So I bought 3 motorcycle scissor stands each for lifting 1100 pounds. All three only 150 bucks on ebay. Quote Link to post Share on other sites
