DIY Boat Dock Air Lift Bag – How I Built It
In this video, I walk through the full build process of my DIY marine air lift bag, which I plan to use to help float my boat dock into place. This is a step-by-step breakdown of how I designed and assembled the lift bag, including the materials I used and my thought process along the way.
While this is just the build phase and I haven’t tested it in the water yet, I’ll be sharing updates once I put it to use. If you’re into DIY marine projects, engineering builds, or just enjoy creative problem-solving, this one’s for you!
Check out my video of using the lift bag to put my dock in the water:
