Remodelling Scarlet Oyster’s Keel

Oyster Lightwave 48. The boat is owned by Ross Applebey and raced competitively with a good record of success, including a win in the Fastnet race in 2007. Ross’s design brief was to improve the boats performance to windward by remodelling the existing lead keel. The project was managed by the owner, who also carried out the construction work.
Rhinophoto provided an accurate but cost effective way to produce the working model.

Using Rhinophoto the existing keel was digitized in and a 3d model created in Rhino.

The ability to superimpose the model onto photos of existing keel assists the verification process

The model was used to inform design decisions and create output for analysis.

The model was used to create drawings for the mould construction and the internal Stainless steel frame for the new composite section.
