Expect tall stories, old engines, and the kind of river craft that make you pause for a closer look.
The little boat that changed everything
The story of Saucy Jane begins in 1954 on the banks of a Canterbury river, when Sir William Hamilton set out to solve a problem that had frustrated generations of river explorers. Shallow, fast water stopped propeller boats in their tracks. Hamilton wanted something that could run where nothing else could. His answer was a small thirteen foot hull fitted with a modest 30 horsepower E93A Ford side valve engine and an experimental water jet known as the Quinnett unit.
That boat became Saucy Jane. She looked simple, even spare, but she delivered something remarkable. With no propeller hanging below the keel, she skimmed across gravel shallows and pushed upstream through rough white water that would have halted any conventional design. Hamilton’s early success with Saucy Jane led directly to the jet units we know today, and the Canterbury farmer engineer became recognised as the father of modern jet boating.
A careful rebuild of a Kiwi icon
The original Saucy Jane now sits safely preserved as an icon of Kiwi ingenuity. She is a reminder of how quickly a good idea can reshape an entire industry. In early 2024, boatbuilder Jim Lapsley completed a faithful replica to ensure that the boat’s history could still be shown on the water rather than only behind ropes. His recreation keeps the same compact lines and light weight that made the first trials so promising, and it stands as one of the most important heritage builds in recent years.
A weekend to honour the past
That legacy will take centre stage at the Saucy Jane Historic Weekend, held from 6 to 8 February 2026 on the lower Waimakariri River. Jet Boating New Zealand and the JBNZ Heritage Trust will bring together classic boats, early jet units, and the people who shaped the sport. The weekend will include river runs, displays, a car boot sale, and a Saturday night gathering at the Racecourse Hotel.
Expect tall stories, old engines, and the kind of river craft that make you pause for a closer look. Above all, expect to see Saucy Jane’s spirit alive on the water more than seventy years after she first proved that a small Kiwi boat could rewrite the rules.
