A submersible dock system with mooring pilings which folds down for storage underwater. The dock system includes a deck or mainspan normally above water, a submerged horizontal frame and, if necessary, leveling structure and a plurality of vertical support structures extending between the submerged frame and dock. The submerged frame, vertical structures and mainspan of the deck are all preferably constructed of rectangular tubing members which are pivotally joined in key places to enable the deck to be pivoted from an upright position to a substantially supine position underwater. The dock system also includes a plurality of telescoping members to hold the deck in an upright position. The height of the dock walkway is also easily adjusted to accommodate changes in water levels. Storage of the deck and vertical structures under water is achieved by pulling pins or other fasteners out of the telescoping diagonal connecting members so that they are free to collapse by shortening or lengthening, thereby allowing the vertical members to pivot about hinged points of the deck and submerged frame. The galvanized steel tubular members are made more corrosion resistant by use of sacrificial anodes and regular performations in the tubular members.
