A hull you can size to the load, and grow when the job does
Two or three hulls of Main Boat Pods, a steel or timber deck frame, and whatever the job needs on top: a crane, a digger, a pump, a workshop. Each Main Boat Pod carries 150kg at half immersion and up to 350kg fully immersed.
- No antifoul and no fuel in the floats
- Add pods for a heavier job, take them off for the next one
- Pods ship by container and assemble on site
Main Boat Pods in two or three hulls
Main Boat Pods carry the most per pod and bolt into hulls of any length. Bow Pods on the front of each hull if the barge is motorised. Raft Pods suit light, static platforms.
6m twin-hull barge
8 Main Boat Pods + 2 Bow Pods. Carries around 1,200kg at half immersion.
8.1m tri-hull barge
18 Main Boat Pods + 3 Bow Pods. Carries around 2,700kg at half immersion.
26-pod pump platform
Carries a 6-tonne pump. Bigger loads are sized pod by pod and checked before we quote.

Work barges built on Pontoonz pods
How much can a work barge carry?
Each Main Boat Pod carries 150kg at half immersion and up to 350kg fully immersed. A 26-pod platform carries a 6-tonne pump. Send us the load and we'll size the hulls.
Does a commercial barge need survey?
If it operates commercially it may need survey with Maritime NZ, or AMSA in Australia. We supply pod specifications and load ratings to your surveyor.
Can I make it bigger later?
Yes. Add pods to lengthen a hull or add a hull for more width and load. The same tie-off points take the extra pods.
How is it delivered?
Pods ship from Auckland to your address or nearest port anywhere in New Zealand, Australia and the Pacific. A container holds 50 Main Pods and 12 Bow Pods.
