DESIGN, MAST AND BOOM

The 35ft QFX lake racer is a project that pushed design and safety factors to the absolute limit where the quest for weight savings was extreme. C-Tech worked closely with Hugh Welbourne, Thomas Jundt, Chris Mitchell and Doyle Sails on this project.

“Working with C-Tech was a pleasure, they were consistently helpful, professional, and went the extra mile to make sure the project was a success."

CHALLENGE #001

Design - weight vs safety

A no-compromise brief from our customer (and engineer) Thomas Jundt who wanted to work to a safety factor of less than 1 as proof that everything is over-engineered in todays world - on a foiling boat!

S O L U T I O N

Close work with designers, engineers and sail makers to understand and study all loads on the boat and optimise the sections. C-Tech used FEA modelling on components and historical rig data to work within known limits. There were a number of design iterations between Doyle Sails, Chris Mitchell at Applied Engineering Services and Thomas to get the balance right.

CHALLENGE #002

Production - complete custom solution

Because the design optimisation process was not constrained by a mould or mandrel geometry (as most projects are) it meant the final design was a new custom shape. The varying section along its length was critical to the get the best aerodynamic and inertia properties. C-Tech uses a male mandrel wrapped autoclave process for the sections so autoclave capable tooling was required.

S O LU T I O N

C-Tech precision-built the custom shaped mould completely in-house. It utilised the 5-axis CNC machine, plotter, autoclave and design experience. Full control of the process ensured quality and integration of all parts.
