Composite Design for a Foiling Optimist Dinghy

In April 2017, a foiling Optimist dingy designed entirely by students, was successfully tested under standard sailing conditions in the waters outside Gothenburg.In order to achieve take of wind speeds as low as 6 m/s, a stiff and lightweight design of the replica beach walk candle dinghy and its foiling components was necessary.There have been few successful attempts to make an Optimist foil in a stable manner, as such there were no standards or recommendations available for the design.Therefore, a simulation driven structural design methodology for hydrofoils, centreboards, centreboard-to-hull connections, and necessary hull reinforcements using sandwich structures was adopted.

The proposed click here design was then manufactured, allowing for a significantly stiffer hull and a 20% decrease in weight over a conventional Optimist.Excluding the rig and sail, the final weight came to 27 kg.
