One-O-One is a beautifully designed and built super yacht, which was recently relaunched at Rivergate Marina after an extensive refit. She is an impressive 36m (118ft), 30 knot plus, composite super yacht built by Technomar of Italy. One-O-One was initially brought to Rivergate from Sydney for Norman R. Wright & Sons to retrofit Humphree Active Stabilizing fins to the hull, for which NRW has specialty structural engineering knowledge and installation skills.
On commencement of the project Norman R. Wright & Sons scope of works expanded to include significant and challenging structural modifications such as the enlargement of the saloon window profile and the installation of hull windows. These structural modifications, including those for the fins, were all completed to a demanding RINA classification. The team also completed a number of deck layout and internal fit-out modifications.
4x Humphree Active Stabilizing fins were installed by Humphree fin provider Ultimate Marine Power. These fins and corresponding hull structure are designed to operate at 35 knots and maintain hull integrity in the event of a fin collision. As can be imagined, the structural loads and required factors of safety are significant. Our work involved:
Full design (with the assistance of our engineering partners ATL Composites and Humphree fin provider Ultimate Marine Power)
The stabilising fins are designed to withstand the weight of 10 Toyota Hilux utes hanging from each fin.
