The permanent one will be built of 55 gallon drums filled with dirt. Any
issues to look out for?

and again build it so the barrels can fall out when they get full of
water or your dock will sink lower and lower.
those plastic barrels will eventually fill all you need them to do is
push up so it costs you nothing to make the darn thing safer

Can you expand on this? I am not sure that I follow you here.
Dan,
With three waterfront houses in the family, we have assembled more than a
few docks.
Is this tidal water ?
Does it freeze ?
Is it open water ?
Is there some kind of boat wake control ?

When I have some answers, I will write about building floating docks and
some very specific things to not do...

It is on a river that only occasionally freezes. The last time it froze all
the way across was 1985. The river's level is quite variable and the
current can be swift. It falls 6 feet in a mile. Our side of the river is
opposite the main channel. It's level in summer is not much to the point
that motors are not normally used. It is Indiana's Whitewater River just up
stream from Harrison.
