Here's what matters: Barrels were once a common DIY dock solution, but they’re prone to leaks, instability, and short lifespans. Modern dock floats are stronger, safer, and built to last—making them the better long-term investment for any dock project.
If you’ve ever walked around a lake or old marina, chances are you’ve seen a dock floating on top of old 55-gallon barrels. For years, barrels were the go-to solution for DIY dock builders. They were cheap, easy to find, and—at least in theory—got the job done. But when you compare barrels to today’s purpose-built dock floats, it’s easy to see why most builders have moved on.
The Case for Barrels (and Why People Used Them)
Barrels made sense back when options were limited. A few straps under a frame, and you had something that floated. The problem is, barrels aren’t designed for marine use. Sunlight breaks them down, punctures turn them into dead weight, and even small leaks can throw off the balance of your dock. And let’s be honest—rolling barrels into place, hoping they stay put, isn’t exactly a foolproof system.
Dock Floats: Built for the Job
Modern dock floats, like our dock float collection, are engineered specifically for this purpose. Rotationally molded shells provide even wall thickness and long-lasting strength, while the EPS foam inside ensures the float still works even if the outer shell takes a hit. They’re UV-resistant, stable in the water, and come with standard mounting points that make installation way easier than wrestling with barrels.
Stability and Safety Matter
A dock should be a place you can trust—whether you’re tying up your boat, hosting a gathering, or just relaxing on the water. Barrels shift, roll, and can cause uneven buoyancy. Dock floats, on the other hand, sit level and stay put, giving your dock a solid, stable platform you can rely on for years to come.
The Value Over Time
Sure, barrels might look like the cheaper option upfront. But a dock isn’t a weekend project—it’s an investment. Dock floats last longer, require less maintenance, and protect your dock (and everyone using it) from the headaches that come with quick fixes. In the long run, that “budget” barrel dock often ends up costing more in repairs and replacements than a dock built with real floats from the start.
Final Thoughts
When it comes to building a dock that’s going to last, the choice is clear. Dock floats are safer, sturdier, and built for the long haul. If you’re ready to get started on a dock that won’t let you down, check out our full line of dock floats here or contact us for help picking the right setup.
