The short answer: cube floats win for a quick jetty you can assemble in an afternoon. Rotomoulded pods win for anything that moves, carries serious weight or needs a hull.
Pontoonz Main Boat Pods
Cube float systems (e.g. Dockpro, Pontoon Plus, OTTop)
Load
150kg per pod at half immersion, 350kg fully immersed
Dockpro: 40kg per cube, about 160kg per m² at 4 cubes per m². Other brands vary.
Assembly
Bolted into hulls, timber or steel deck on top
Pinned together, deck surface is the cubes. About an hour for a small jetty
Pontoonz sells both: rotomoulded pods made in Auckland and the imported Dockpro Float Pod. Competitor figures beyond Dockpro are not stated here; check each manufacturer's published specs.
