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. Our 36" wide round floats use a large-scale bolt-together aluminum frame system and the frame systems for our Mammoth floats use hefty galvalized steel components.

These are not one-size-fits-all systems, and to be frank, we NEED to have a phone 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 actually speaking with you! 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 sheet listed for our large barge systems with 36" wide round floats. Our Mammoth Dock Float barges are very time consuming to price out and we will not be pricing out every option on our page (see our description). If you want to discuss anything about these big systems, PLEASE CALL US.

ALUMINUM FRAMED BARGE SYSTEMS
WITH 36" WIDE ROUND FLOATS

This system uses our proprietary HD Main Beam extrusion for the backbone of the pontoon assemblies and our 4" tall HD Hat Channel crossmembers to build your frame. 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'
Max frame width (Crossmembers): 12'

With this system, you can build boats with 2 or 3 rows of floats, dependant on your needs. We also offer 60 and 150 HP capacity transoms for this sytem. 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 typical configurations.

OUTBOARD MOTOR SHAFT LENGTH REQUIREMENTS:

Our large barge systems require XL shaft length outboard engines (25" or longer shaft length) when using our 60 or 150 HP capacity transoms. Also, the overall weight of your engine needs to be taken into consideration when selecting your outboard. Our 150 HP capacity transoms are rated for motors up to 400 pounds, and some 150 HP outboard motors are over this threshold. Please SPEAK with us before purchasing the outboard for your barge.

MAMMOTH FLOAT 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 16'x39' 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.
