Push the limits & reach your targets!

Dedicated to racing yacht optimization. 
From the design board to the race track.


VPP, CFD & Design coordination


Remote and on-site performance analysis.


From Dinghy to Grand Prix sailing

Design services: CFD & VPP

CFD Services: 
We have developed methods that allow us to apply the best tool to a specific design problem. From simpler panel code methods to the most advanced RANS models with multiple degrees of freedom in waves, we offer sensible solutions to make sure budgets are spent in the most effective way, maximizing the benefits for your project. 
We perform our simulations relying on the Das Boot panel code and STAR-CCM+  RANS solver. Numerical models are run on KND parallel server as well as a remote cluster featuring several hundred cores. Most hydro matrixes are computed within 24 hours.

VPP Services: 
KND has 15 years of experience developping racing yacht VPPs.  We work with the North Sails VPP, enjoying a very close relationship with its developers. Our VPP modeling capabilities range from the 'standard' fixed keel monohulls configuration to mutihulls and fully foiling yachts using 6 dof. 
Our proprietary aero coefficient libraries can be scaled to fit most yacht design programs. In additions, we regularly work with sail designers to develop custom libraries for the most advanced projects. 
KND will provide an efficient evaluation of the performance of any given yacht. 

Feedback loop:
Last but not least, we have developed a link between our VPP and sailing data analysis allowing us to constantly validate our numerical against real data and refine the accuracy level of our predictions for new yachts.

Performance analysis

KND vision relies on an in depth understanding of sailing yacht performance. Along the years, we have built a wide knowledge database and developped methods to deliver more effective analysis and reduce turnaround time. 

We gathered through the years a group of expert engineers, working collectively to develop our tools and methods. Each team member has a wide experience of inshore and offshore  performance analysis, from fixed keel to fully flying yachts. 

From electronics calibration, to performance reports (starts, strategic, maneuvers, performance, fleet...) our support yields better debriefs, checking sailor's feelings against valid & relevant data. 
You will be able to quantify performance gains and develop your polars and sailing targets.  

Custom data analysis and reporting can be provided as a remote service or on site (and even on board) depending on the specificities of each program. 

Performance software

Building on KND's expertise in performance analysis, we constantly develop software to make our work more efficient. We believe that these tools can help all sailors who want to look into logged data progress toward squeezing the last % of performance from their boat.

ReXY Gold is meant to provide single and multi-boat analysis for sailors relying on a gps tracker only. 
ReXY Team will provide detailed insight for the most advanced programs. It works jointly with RaceReplay and PerfQuery performance analysis programs.
