One more thing, there are quite a few docks that fit this formula, don't get married to a single one. A lot of these docks show that some valid forethought went into their placement. The relatively minimal kit required by this approach allows one to move between docks very easily. Set up a route and move between them, until you hit the fish. If you cannot find them one place, they will be some place else; so do not overstay any spot that is not producing.
