The yard arms have jacks built into them, and like said above...they are very expensive.

And I doubt most marina's well let you just borrow one. Liability issues.

Funny chit but, on a serious note; if you're going to do this in your backyard as you mentioned, think about settleage. If you do it on ground/grass, there is a definite danger of settling and falling on your face!!! You should use very large bases to distribute the weight as much as possible.

You've probably considered this but if not, I'd hate to be reading about you in some thread on OSO. Good luck and check everything twice.

Not to appear overly simplistic, but what if you put the jacks in place then deflated the trailer tires?

Maybe overinflate them first for even more drop when deflated? Seems like that would give you an easy 5-6 inches.

Why,,,don't u just go to a local maina ,,,and pay them 200 bucks to lift your boat of and use there yard to clean the hull and have it set back on the trailer ??????

1 saturday and u be done !!!

I think 200 bucks is well worth it !?

That's good advice. I blocked my old 242 off the trailer once using a backhoe. It worked but I was frickin' nervous the whole time. Knowing what I know now (older and more conservative) I'd go with the marina idea.

Thing is, I want to re-do my bunks. I need to trace the hull so I can cut notches into the bunks for the steps, etc. I didnt want to feel rushed at a marina. So it's not just cleaning the boat.

Leave the trailer under the baot and jack the boat up one section at a time. Clean the spot,set the boat down and move on to the next section.

If all you want to do is wash it,get some Dawn ultra concentrated dishwashing liquid have some one lay on the front of the boat [life jacket on,safety first] running about 25 and pour the detergente in the water,the props will make big suds just like your sink.Turn around and drive through it fast. that will clean the whole bottom! Dawn is biodegradable! problem sloved!

The only reasons a boat needs to be clean between the bunks:

You keep on davits and hoist very high, or

You plan to get drunk at beach and let tide go way out and want a shiny hull to reduce your embarrassment, or

you plan to roll the boat, swim to safety and watch the rescue crew slip and slide while trying to rescue you.

If you really want to go through with it, take the easy route. Hire a bulemic, crack-addicted Hooter's whore and pay her to shimmy between the bunk and rub it down.

Jeesh, i gotta spell it out for you.
