Boats, Houseboats, Leisure craft
As long and wide as you want
The beauty of the Pontoonz system is that you can assemble the plastic pods to the hull configuration you need to float what you want.
Once assembled, construct a platform directly onto the pods (simply done with timber runners and joists drilled and bolted) then add your shelter and accessories. Design to your wants and needs. Keep it simple, or add all you need to live well on the water.
