In the 1950s, driven by a desire to power around the shallows of the Mackenzie Country's braided rivers, inventor and "South Island sheep man" Bill Hamilton developed an improved method of jet boat propulsion. This NFU film explains the concept and Hamilton demonstrates the 'turbo craft': cruising Lake Manapouri, waterskiing Lyttelton Harbour, and heading up the Whanganui. Then it's spin outs and shooting rapids (and deer) with Commander Philip Porter from the icebreaker USS Glacier...who clearly loves the smell of the Waimakariri in the morning.
Someone always has to do that turn-in-your-length trick.– From the narration
