- The Q28 was lightning fast in light winds. She was "motorized" like an Esse 850 and weighed 550kgs. Of this a meager 170kgs as ballast...
- ...and even faster in wind and incredibly stable and calm at the same time - as long as you sailed fast enough to compensate the growing heeling moment with the help of the lift on the foil - which was not always successful and also not easy.
As already described, the Quant28 inspired us to go one step further. This refers to the development of the Quant23, which we saw as a "foiling sports boat" rather than a pure foiler soon after the first strokes. It is not only the first flying keel boat, but also the only boat in the world that can handle all four known sailing modes: displacement sailing, planing, semi-foiling and full-foiling. This means that the boat practically always sails in an optimal mode, even in very different conditions (link to Quant23 brochure, pdf for download).
This is a very important prerequisite - on the one hand for psychological reasons, but on the other hand also because in areas with unsteady winds, pure foilers can only play out their great potential with difficulty. As far as I know, the Bol d'Or has never been won by a foiler - not even close.
Although the QFX can undoubtedly be called a foiler, it is effectively a hybrid. She has a rich 'toolbox' that allows her to always choose the sailing mode that will deliver the most benefit in the prevailing conditions. This freedom of choice will also enable the skipper of the QFX to choose the more direct route to the next course mark or destination more often than others, thereby also keeping the distance sailed lower.
We are very curious to see how far these theses will be confirmed. Stay tuned.
The topic "Foils" is still very new for many - we are happy to share our knowledge and experience with you.
