ACT provides the design service for racing yacht superior in performance optimized for the clients' requirements and specified conditions/rules to be competitive in races and to have good balance in operation by use of the advanced scientific methods.

​

We also design racing dinghies for which a hull form is the key point in a limited design space by each rule. Every corner of a hull form should have hydrodynamic meanings and need detailed considerations to decide the shape.

​

We offer the best solution to improve your sailing boat performance by looking at the current sailing performance with our original data analysis system, checking the boat balance, considering the possibility of changing keel, rudder and/or sail plan, and comparing the performance with the rating system.
