How to Make a Floating Dock

Building a floating dock is somewhat challenging, however, a floating dock is beneficial to any boat owner. A floating dock rises and lowers with the tide, allowing it to stay at the same water level as the boat attached to it.

Things to have on hand:



  • Drill

  • Spiral nails

  • Tape measure

  • Galvanized screws

  • Galvanized steel corner brackets

  • Plastic foam billets

  • Galvanized carriage bolts

  • Galvanized nuts and washers

  • Eight two by ten inch pressure treated boards

  • Two by four pressure treated boards

  • One by six inch pressure treated boards

  • Saw



  1. Cut the two by ten inch pressure treated boards to the size that you need for your dock using the saw. This creates the frame of your dock.

  2. Bring the corners together using the galvanized steel corner brackets. You will need to mark holes on the wood where you need to attach the brackets to the wood.

  3. Secure the corners by bolting them.

  4. Place a block of two-inch wood as a spacer and then repeat step one through three to make a double frame.

  5. Put the plastic foam billets in the frame by putting one in the middle and one on each long side of the frame.

  6. Measure every sixteen inches; this will be where you will place the crossties.

  7. Put the cross ties in place by screwing each two by four board along the sides of each foam billet. This is the retainer.

  8. Place one retainer on each side of the foam billets in the middle and one on each side of the side billets to hold the frame in place.

  9. Cut the one by six inch boards to the exact size you will need for your dock.

  10. Nail the boards onto the top of the frame using the spiral nails.

  11. Nail the boards onto the cross ties.

  12. Slide the dock into the water.
