HOW OUR SYSTEMS WORKS
Our large-scale pontoon barge systems are for folks that need to float very heavy loads. These systems work great for work barges, houseboat systems, floating equipment platforms, floating research platforms, and floating service platforms. Our large barge systems use our super durable, foam-filled, 36" wide HDPE round pontoon floats or our massive Mammoth Dock Floats, and we have multiple framing concepts to choose from. If you are building a non-powered, or at least slow-moving barge, check out Frame Option C at the very bottom of this page. For those who are powering their barges, you'll want to check out Frame Option A and B below. These are not one-size-fits-all systems, and to be frank, we NEED to have a conversation to talk through what would work best for your scenario. If we've learned anything about building large barge systems, it's that every customer has their own needs, and this is the reason for multiple frame system. If you are interested in building one of these barge systems, please call us if at all possible. Pricing is a moving target when it comes to systems this large, and we're doing our best to have current price sheets available for anyone to view. We currently have a full price sheets listed for our common size full-aluminum frame systems (Option A) and our hybrid-frame barge systems (Option B below) that use our 36" wide round floats. Option C is a concept that we will not be pricing out completely (see our description). If you want to discuss anything about these big systems, PLEASE CALL US. |

FRAME OPTION A: FULL ALUMINUM FRAME
AS OF 11/11/25 WE ARE MAKING MINOR UPDATES TO FRAME OPTION A AND OUR PRICING CHART FOR SMALL TRANSOM BARGES WILL HAVE MINOR INCONSISTANCIES. PLEASE CALL US IF YOU ARE INTERESTED IN ONE OF THESE KITS.
Framing option A is our full aluminum frame system. This system uses our proprietary HD Main Beam extrusion for the backbone of the pontoon assemblies and our 4" tall HD Hat Channel crossmembers. This system bolts together just like our smaller boats, but is MUCH beefier. The aluminum extrusions we use for this system are shown below.
This system has its pros, cons, and limitations. Here's a simpe run-down: PRO: Easy to assemble, fully adjustable cross-member placement, all frame members are aluminum, includes all required stainless assembly hardware. CON: Shipping for frame system can be costly if not in the New England area and going with a larger system due to the length of the Main Beams. DIMENSIONAL LIMITATIONS: Max frame length (Main Beams): 30'
With this system, you can build boats with 2, 3, or 4 rows of floats, fully dependant on your needs. We also offer 60 and 150 HP capacity transoms for this sytem, which can be configured with or without nose cones. How you need your barge to be is how we'll configure your kit. Below and to the right we have provided full CAD files and current pricing for common configurations.

FRAME OPTION B: HYBRID FRAME SYSTEM
AS OF 11/11/25 WE ARE IN THE PROCESS OF REPLACING AND UPDATING THE INFORMATION FOR OUR HYBRID FRAME SYSTEMS. PLEASE CALL US IF YOU ARE INTERESTED IN ONE OF THESE KITS.
Framing option B is our hybrid stainless (or steel by spcial request) tube backbone and aluminum crossmember frame system. This system allows for longer barges than our full aluminum frame system (up to 36' with our standard configurations), but will require some expert-level welding for barges longer than 20'. This system uses laser cut 2"x6", 3/16" wall 304 stainless steel main tubes (fit into the top of the floats) and our heavy-duty 4" tall, 1/4" thick 6000 series aluminum hat channel. There are no brackets to weld in, but you do have to drill the bolt holes into the main tubes (holes come molded into the floats), and if you are building a boat longer than 20', you will have to splice the main tubes. Please be aware that the tube splicing is an expect level task, so novice welders should not attempt this work. With this system, bolt holes and lock nut access widows come cut into the stainless main tubes. This allows for very simple assembly. Also, no local materials have to be purchased for the primary frame construction of the barge. If you've been watching our page for a bit, the prior version of our hybrid frame system required a fair amount of welding (crossmember mounting brackets had to be welded in). This system eliminates all that fussy welding and only our longer kits require a little bit of fussy welding now!
This system has its pros, cons, and limitations. Here's a simpe run-down: PRO: Less shipping cost when building longer barges, frame is more resilient to extreme and abusive use CON: Longer systems require experienced welder to splice main tubes of frame, frames are slightly heavier than full aluminum system DIMENSIONAL LIMITATIONS: Max frame length (Main Beams): 36'
With this system, you can build boats with 2, 3, or 4 rows of floats, and we offer 60 and 150 HP capacity transoms. For specific applications, this system can be configured with or without nose cones as well. How you need your barge set up is how we'll configure your kit. We have provided specifications, full CAD files, and current pricing (with full 304 SS/aluminum HD Hat Channel frame) for common configurations of this system below. If you need to shave further cost out of this system, a steel system can eliminate as much as 1/3 from the total cost before rust-proofing frame components.

FRAME OPTION C: GIGANTIC FRAME SYSTEMS
FOR STATIONARY BARGES
If you need to build a gigantic floating platform, this concept is the way to go as it makes use of our Mammoth Dock Floats, which each take over 6800 pounds to sink! This framing system is unique as it's a departure from any of our other framing concepts. These systems can be up to 48' long (per barge module), 18' wide, and use both custom formed galvanized steel channels and our HD hat channel aluminum crossmembers. Also, these barge systems can easily be made to join multiple modules together, so if you need a 100' long barge, that's easy to accomplish. This is a completely bolt-together, all-inclusive system and is made specifically to fit the needs of each project.
As an example, we'd like to show you our 39'x16' floating barge platform. Why 39' and not 40'? At 39', the frame system can fit into a 40' shipping container and ship just about anywhere in the world. If you want to build a system like this, please check out the full CAD file listed below and contact us to talk about what it'd take to make it happen. As of 9/19/25, the current price for our example system comes to $88,404 (before freight) and the capacity of the assembled system (before any decking or accessories) at 75% submersion of the floats is approximately 35,258 pounds.
