How to Build Hanging Dock Hammocks

If you have an existing dock, adding a cantilevered hammock can be a quick and easy way to increase the relaxation areas without taking up deck space.

Start with a layout. Existing posts on a 6-8' center are ideal for this setup. In our case, we chose an L-shaped layout with two 4'x8' hammock areas. We also chose to install the hammocks 18" above the deck to make it easier to get in while not creating a fall hazard.

Next cut two 2x8's per hammock panel to 4' and angle cut the outer ends to 5.5". Drill two 5/8" holes 4" apart on the inner end and mount to the posts with 5/8" carriage bolts, washers, and nuts. Using the post and the horizontal 2x8's as a guide, mark and cut 22" gussets from another 2x8. Mount the gusset to the post with a 5/8" carriage bolt.

Using a wood clamp, secure the gusset to the horizontal 2x8 and drill two 5/16" holes approximately 8" apart using a long drill bit. Next, pass the 1/4" threaded rod through each hole, install a washer and cap nut on one end, and trim the other end to 1/4" long with the reciprocating saw. Finally, install a washer and cap nut on this end, making sure it tightens the horizontal and gusset 2x8's together.

Using a bit driver install a 2x6 across the 2x8 horizontals with (2) 3" coated wood screws at each.

Because we were also framing a new roof, we extended a hip beam out to help support the corner of the hammock framing. A 1/4" coated cable and clamps were used between the two. If you don't have a similar condition, install a diagonal gusset from the far corner back to the deck posts.

Install screw eye hooks around the perimeters of the frames to support the hammock panels.

Install the hammock panels by clipping the outside rope through a spring loaded carabiner the clip that to the screw eye hooks. Be sure to pull the panels tight as they will stretch slightly over time.

Now lay back, relax, and enjoy your new custom hammocks with some outdoor pillows.
