I slightly prefer a fixed dock (stability), but to be honest I am running into a problem finding a professional dock builder to do it. I've spoken with two dock building companies and they both said the way they do a fixed dock is with a barge. One guy has a 37 foot barge and the other a 28 foot barge. And they don't think they can launch a barge that large into a 4 acre lake with no ramp. So I may have to go with a floating dock (like shown below), which wouldn't be the end of the world.
