The Impeller is an option for CoxOrb Platinums only and you will need either a Impeller Loom Adaptor or Platinum Connection Harness fitted for it to work. The impeller design was optimised using Computational Fluid Dynamics software and its drag matches the alternatives that are available. However all impellers create significant drag so we recommend that it is only used for training and is removed for racing. Every effort has been made to make our impeller as practical as possible: it can easily be fitted and removed using 3M Command Adhesive Strips, the spinner is supported at both ends to ensure it is robust, and it has a clip on ‘keeper’ to prevent wear while in transit.
The location of the Impeller affects the readings it gives due to the changing turbulence along the boat. If the boat is primarily used on straight courses we recommend that it is mounted near the cox, for convenience, and that it is then calibrated. If the boat is not just used on straight courses an Impeller Extension Lead should be used to position the Impeller approximately 5 metres from the bow.
All our wiring components are fully compatible with NK wiring so can be used as replacements on existing systems.
We are always looking to make improvements so welcome any further suggestions!
