I did not get my post in to support my floating dock last year so I only have a couple of weeks before the water starts back up.

I plan to use 6" PVC with a Steel pipe in the middle, all filled with concrete.

They will be in 8 feet of water at Full Pool.   Does anyone know ( or at least have an oppinion on) how deep I should bury the pipe?

Thanks

I drove my pipe in about 8' and that seems to be working well.

In my experience there is no one set answer.  Many factors must be considered i.e.; type of bottom (sand, mud, chirt, bedrock), the number and sizes of boats to me moored, and last but not least is location. If you are on big water with constant trafic you may need to go deeper than if you are in the back of a creek or long slough.  I also think that if McGill has had good results then 8 feet ought to cover it about anywhere on the lake, but may be overkill in many areas.  I know where some are that only went 4 feet and have gotten great performance also, but those are in low traffic areas.  I would seek advice from someone that has actual knowledge of your unique situation.

For our floater, I sunk the posts 18-24 inches deep with a a concrete footings.   The pier is about 8x16, and stands up to waves pretty well.... however, I distributed the load on 4 seperate posts.  

Wave action is getting more problematic in our area, especially with so many boats designed to create large wakes for wakeboarding....  better to over-engineer it rather than build it twice!
