As early as 1971, hull shapes are designed by Jean-Marie Finot on one of the first Hewlett-Packard computers, using a proprietary software developed in-house. This ground-breaking piece of software enabled him to evaluate heeled hulls, using criteria aimed at minimizing the transfer of energy to the waterflow.

It evolved along the years and is still used by Jean-Marie Finot. New hull shapes developed by finot-conq are designed directly within our 3D CAD tool, but evaluated with the same criteria.

Our boats are entierly modeled in 3D. This gives better inputs for the weight schedule, and allows to identify interferences between parts earlier and easily. Parametric and associative modeling enables us to automatically propagate any modification to the entire model. This saves weight and make testing a larger number of configurations possible. This time-tested method has been in use at finot-conq since 2002.
