That's a good point regarding if the water is deeper than 5 feet it can get dicey using the jack.

It's a little deeper than that at the end of the dock. My dock is heavy, its a wood dock about 6' wide and I'm guessing it's 8' or more between posts so when I get back to NH I'll look at it again and decide between using a farm jack vs a small commercial airbag and compressor.

After reading one of these recent posts I now understand why my 4"X 4" posts are tilted in different directions, its because the cross members under the dock are mostly missing.

This is all great information. I can't wait to get to it now that I don't have to pay someone who probably would charge $400+ and show up with a farm jack and an inner tube.

Thanks.
